How to make your own Sourdough Starter, using simple ingredients with no special equipment, in just 6 days, that can be used in sourdough bread.  Sourdough Starter is a “wild” yeast, made from flour, water and the wild yeast in the air around us- used to replace store-bought yeast. (Step-by-step VIDEO.)

How to make your own Sourdough Starter, using simple ingredients with no special equipment, in 5-8 days, that can be used in crusty bread, pizza dough, waffles, pancakes, and rolls- instead of using yeast. Sourdough Starter is "wild" yeast, made from flour and water and the wild yeast in the air around us. When you understand one thing through and through, you understand everything.~ Shunryu Suzuki

Hey friends, I’ve wanted to share this recipe for  Sourdough Starter for years now, and with most of us being homebound, and without yeast available at the grocery stores, I thought this might be the perfect time to post it.   As you know, we are in Santa Barbara for the winter, and one thing I didn’t even think to bring with me was my sourdough starter.

I made a fresh batch of starter last week, and baked a loaf of  Sourdough Bread yesterday- and felt so much joy from this simple pleasure. The whole process honestly fills me with such wonder. How gloriously alive the world is! Plus there really is nothing like the smell of fresh bread to lift the spirits.

If you find yourself with a little more time on your hands, this might be the perfect opportunity to discover the joy of baking sourdough bread from your very own sourdough starter.  You can also make baguettes, pizza dough, waffles, banana bread, pancakes,crackers, sourdough buns,  sourdough tortillas and biscuits.

It’s truly incredible! The basic instructions were taught to me by a friend, who adapted it from Breadtopia and King Arthur Flour. I’ve taken liberties and further adapted, but both are great resources.

What you’ll need

What is a Sourdough Starter?

  • Think of sourdough starter as yeast. Only in this case, instead of buying a packet of yeast from the store, you are making your own living “wild yeast” by fermenting flour and water.  That is it! ONLY 2 ingredients!  Once it’s alive, it is like a very low-maintenance pet.
  • You must feed it (stir in a mixture of flour and water) once a week to keep it healthy and happy. You know it’s happy when it bubbles. 😉 And YES, you can even name it.
  • Some people believe that bread made with sourdough starter is actually better for you than bread made with yeast. Here and Here are a few articles to get you started on your own research. While I’m not sure if this is scientifically proven, I do know that bread made with sourdough starter, tastes infinitely better, feels easier to digest,  and has more complexity and better texture, than bread made with commercial yeast. So if you are a bread lover- this is absolutely the way to go, as far as the quality of your finished bread.

What is Feeding?

  • Feeding your sourdough starter is basically adding a mixture of flour and water to your existing starter, to keep it alive, happy, and nourished. Starter is full of wild yeasts that get hungry, just like we do. These yeasts need “food” -in this case, more flour, to stay healthy and active.
  • How often you feed depends greatly on the temperature of your home. The starter will metabolize the flour more quickly in warm environments, and more slowly in cold environments (like the fridge).  If you keep your starter in the fridge, you should only need to feed it once a week. If you keep it on the counter you may need to feed it 1-2 times daily, and sometimes more if you live in warmer climates.

 Sourdough Starter (step-by-step instructions)

This recipe for Sourdough Starter takes 6 days (or up to 12 days if cold) and is very easy. This was the way I was taught and it always works for me.  There are plenty of more complicated recipes out there, and I get it, if that is more your style – or you feel like completely nerding -out (a good thing, and this is the time!) dive in. Feed your fancy! Or watch the 20-minute Sourdough Video above!

Day 1: Staring in the morning or at night, using a wide-mouth quart jar, tulip jar, or Crock or Glass Measuring Cup , mix 1 cup whole grain flour  (fluffed, spooned and leveled) -or 120 grams-  with 1/2 cup (120 grams) filtered water using a fork (or chopstick) making sure you’ve incorporated all the dry flour.

Place the lid lightly on top (using the Weck jar is really handy here) or a wet towel to keep moisture in, or plastic wrap- and let sit at room temperature ( 70-ish degrees) on the kitchen counter for 24-48 hours. If you are not sure how warm it is, use a kitchen thermometer and check it a few hours later. See notes for TEMPERATURE.

TIP: For your first measuring – it is a good idea to weigh the flour using a kitchen scale so you get an idea of how it should feel. Do not weigh the cup. It should be like a thick paste. Thick like peanut butter. If you need to add a little more water to incorporate the flour, that is OK.

Day 2: After the first 24 hours, there may or may not be a bit of bubbling. Let the mixture rest until you see activity (bubbles or rising) sometimes this takes 36 hours or even 48 hours if very cold. When you see active bubbling, discard all but 1/2 cup of the starter (4 ounces).  

To the remaining ½ cup of starter,  stir in 1/2 cup water (120 grams), mixing well with a fork and 1 cup of organic bread flour (120 grams) spooned and leveled. Stir until combined. Again, it should feel like a thick paste. If overly dry, feel free to add a bit more water.

Cover again and allow the mixture to sit at room temperature for another 24 hours.

Day 3: After 24 hours, hopefully, you will see some bubbling or rising and if not, let it go a bit longer until you see activity. Be patient.

Depending on how warm your house is and how active your starter, you may need to begin feeding more often or move to two feedings a day,  in the morning and at night.

In a nutshell, you want to feed the starter only after it has peaked (metabolized all the flour from the last feeding) and has started sinking down or gets liquidy- this is when it is hungry!

This might be 12 hours, it might be 14, it might be 18, or 24, depending on the temp in your house. In very warm climates it may only be 6-8 hours.  In winter, this may take 36 hours. It is better to underfeed rather than overfeed here. For each feeding, like before, discard all but 1/2 cup of the STARTER (keeping roughly  ½-cup of starter in the jar) Add 1 cup Bread Flour  (spooned and leveled) and 1/2 cup water to the 1/2 cup starter and let this rest at room temperature for 12-24 hours or until the starter looks “hungry” again before repeating.

Day 4: Feed 1-2 times,  discarding all but 1/2 cup of starter EACH TIME. Feed 1 cup bread flour, 1/2 cup water.  Day four is typical for the starter slow down and stall a bit. This is OK. Just keep going, and look for the hunger signs, and only feed when clearly hungry.  This may look like liquid on the top, or very runny starter (to the point where it can easily pour out of the jar). But hopefully, you’ll begin to see some rising and falling. It’s helpful to put the starter in a clean jar each day and mark the beginning level (with a sharpie, string or rubber band) so you can easily see this.

***If for some reason your starter looks like it is still rising at the time of second feeding (at night) and there is no evidence it has fallen or no slide marks,  skip this feeding and feed first thing in the morning.

AGAIN, feeding it when it is  “not hungry” will basically dilute all the growing yeast and make it lethargic. Better to starve than overfeed. 

 

sourdough starter with slight bubbling

Above you’ll see it peaking, below you’ll see it deflating and getting “hungry”. Feed when the starter only when it’s hungry. This will can vary in time greatly – so even though there is a loose schedule laid out for you here, understand that your starter has a schedule of its own, it is a living thing- so watch it and pay attention!  

I repeat: The key here is to watch it. Don’t feed the starter until it looks hungry. Overfeeding a starter makes it lethargic. 

Look for the signs of “hunger”: You’ll see watery bubbles at the top or even a layer of liquid. See how below on the jar, how the starter slides down the side of the jar? Look for the “slide” marks just under the Weck logo.

If your starter is not rising and falling, look at consistency. As it metabolizes the flour and gets hungry, it will get runny and liquidy, like to the point where you can pour it right out of the jar. If it is still thick like paste, it’s not done metabolizing (eating)the flour.

Day 5: Feed again, 1-2 times, roughly 12 hours apart, discarding all but a 1/2 cup the starter EACH TIME. 1 cup bread flour, 1/2 cup lukewarm water. The starter should look visibly active, bubbling, rising, hopefully, close to doubling in size.

You may need to repeat day 5 until the starter is rising and falling predictably and is close to doubling in size within 6-8 hours.

TIP: If your starter is not rising but there is evidence of hunger (liquid at the top) try 3 things: substitute 1/4 cup whole grain flour (add to ¾ cup white bread flour) on your next feeding. Try using mineral water like San Pellegrino instead of water.  Stir the starter a couple hours after feeding to allow wild yeast from the room to get in there. 

DAY 6:  Baking day!  Give it one last feeding in the morning. Discard all but a 1/3 cup. ( The reason we are changing this to 1/3 cup is to feed it a little bit more.) Add 1 cup flour (120 grams) and 1/2 cup water, and place it in a clean jar so you can see the action clearly.  You can use a sharpie or place a rubber band around the jar to mark the beginning level. The starter should hopefully double in volume within 6 hours of feeding.

Then DO THE FLOAT TEST: To test the starter, place a teaspoon of starter (just from the top, don’t stir it down) in a glass full of water, it should hopefully float. If it does, you can make bread. Tonight! If it doubles in size but does not float, you can still give baking a try. Let the starter rest at room temperature for at least 8 hours allowing it to fully metabolize the flour, perhaps sinking a little before making your dough.

At this point, if your starter does not double in size within 6 hours of feeding, don’t give up! Often, it just takes longer, especially during the winter months. Continue feeding one to two times a day until you see a consistent, predictable rise and fall.

Read the troubleshooting section. If you need to take a break, put it in the fridge and try it again up to a week later. Don’t toss it.

Day 6 EVENING: Use 1/3 cup to make this sourdough bread (if you want)and place the remaining starter (or if not making bread, place all of it)  in the refrigerator, and feed it at least once a week, mixing in any liquid at the top, reserving ½ cup starter, before feeding it the usual 1 cup bread flour, 1/2 cup water.show the slide marks on the sourdough starter jar

In the photo above, on the 6th day, the starter was fed at 8 am, it doubled at noon, but went even higher until around 2 pm where it peaked. Then as you can see, it started deflating and by 8 pm, it was lower, and “hungry” again. See those downward “slide” marks on the jar?  

Look for these! That’s why it’s nice to put the starter in a clean jar so you can see these clearly.  They tell you how high your starter went and that it peaked, and now is going down. Even at 8 pm, it passed the “float” test, so I started a loaf of my sourdough bread at this time.

TIP: When making bread, you want to use starter that has already peaked.

Signs of hunger:

  • Slide marks (be sure to use a clean jar so you can see these clearly).
  • A layer of liquid at the top of the starter
  • The starter is thin and liquidy enough to pour out of the jar (when at room temp).

TROUBLESHOOTING:  

  • SMELL: Starter should smell sweet, tangy, earthy, like a wet horse – not “bad”.  If it really smells foul or unpleasant, you may have used an unclean jar, unclean utensil,  or somehow introduced other bad bacteria. I would start over.
  • NO ACTION: On day 4-5 it is typically for it to slow down. If your starter is not rising at all but there is evidence of hunger (liquid at the top, or bubbles) try 3 things. First substitute 1/4 cup whole grain flour (add to ¾ cup white bread flour) on your next feeding. If no rise, then try using mineral water, specifically San Pellegrino instead of water.  San Pelligrino specifically has the right mineral ratio, I have great luck with it. Others not so much! Also try stirring the starter a couple of hours after feeding, a couple of times throughout the day to allow wild yeast from the room to get in there. Lastly, you could try pineapple juice instead of water.
  • FLOUR: Try to use fresh milled whole grain flour to start, then organic BREAD FLOUR. The more wild yeast in the flour, the better your starter will do- so smaller brands like Bob’s Red Mill seem to do better than bigger conventional brands that have been overly processed.  It is totally OK to mix flours and to switch them up- this adds different kinds of wild yeast- a good thing!
  • DO NOT overfeed. For example, maybe feeding 2 x day at 12-hour intervals is too often. You want to feed after the starter has peaked, then deflated (see photo above- you’ll see some slide marks on the jar) and this tells you that it is hungry. If you feed the starter before it has had a chance to metabolize (or eat) all the flour (before peaking) and then you discard part of it, and feed it again, you are actually diluting all that amazing bacteria, weakening your starter.  So it’s all about watching your starter in your home. If you are not seeing rising and falling, but notice the starter just gets liquidy, this too is a sign of “hunger”.  Or if it gets runny enough to pour out of the jar, another sign it is hungry. There are lots of variables here. Just be patient, pay attention and watch. This is a living thing- it doesn’t care about time schedules and recipes or what it “should” do. It will “eat” when it is “hungry” and sometimes it likes to eat slowly. 😉
  • TIME: It may take longer than 6 days in colder environments. Use a kitchen thermometer and take its temp. Is it over 65F? Find a place where it can be warm. In the oven with the light on, or in an upper cupboard ( heat rises).  Sometimes it takes 12-14 days! Be patient, keep going. If it is doing absolutely nothing, leave it out on the counter for 24-48 hours and see what happens. If you run out of flour or need a break, don’t just toss it, put it in the fridge and see if you can get it going a few days later.
  • ACIDITY: If you still can’t get that starter going, some people recommend subbing pineapple juice for the water for one feeding- raising the acidity level. My good friend just tried this and it got hers going.
  • LIQUID: If you see any liquid at the top of your starter, it means your starter is hungry. So, yes it’s still alive which is a good thing! You can stir the liquid in, or pour the liquid out, either way, but feed it. This is a sign that you may need to feed it more often.
  • MOLD: if you see any discoloring or mold on the surface, starter was probably contaminated. If it is only on the surface, it is probably ok to save. Scrape it off, save 1/2 cup of the underneath starter, and keep going, using a clean jar. Feed, smell, use your best judgment.
  • FLOAT TEST:  Try testing when your starter is peaking. Take a spoonful from the top without stirring it down. If your starter is rising and falling consistently, but not passing the float test and it has been over 8-10 days- just try baking a loaf. People are having luck with good loaves without passing the float test. It may be the flour…

How to Maintain Your starter:

  1. REFRIGERATE & FEED AT LEAST ONCE A WEEK: Pick a scheduled day and try to stick with it, always reserving 1/2 cup and feeding it 1 cup flour and 1/2 cup water. Discard the remaining, give it away, or keep the discard in a separate container for waffles, pancakes, sourdough buns, banana bread, biscuits, etc. I usually don’t feed the discard unless I give it away.
  2. If you forget to feed it one week, it is most likely OK; feed it 1-2 times a day for 1-3 days in a row to revive it (keeping it out on the counter) until bubbly and active and doubles within 6 hours.  I’ve left my starter for a month on vacation (in the fridge) without feeding and simply revived it by feeding it 3 days in a row, 1-2 x day. It’s surprisingly hard to kill. You can also freeze it for more extended storage.
  3. This batch will allow you to bake 2 loaves of bread per week with enough left to feed for the next week. If you find yourself wanting to bake more often, you can keep it out and feed it 1-2 x daily. Or if baking every few days, you can pull it out of the fridge, feed it 10 hours before using, leaving it out, use what you need while it is peaking (or slightly after), then put it back in the fridge that evening. Do the same thing a few days later when ready to use again. So this would be feeding 2-3 times a week, best if baking 4-5 times a week.

Tips on Sourdough Starter:

    1. TEMPERATURE: The colder your home, the longer it will take for the starter to grow and become active (bubbles). Find a warm spot (70-80 degrees) for the best results. On the stovetop, with the light turned on, or on top of the fridge. Or in the oven with the light on. On top of a heating pad (set to low) with a towel in between). You can still make the starter in a colder home, it will just take longer- even up to 2 weeks! Test the temp of your starter using a thermometer.
    2. FLOUR: Always try to start the batch by using organic whole-grain flour (wheat or rye) because it has more wild bacteria in it than white flour and will get it active and growing sooner. Freshly milled works exceptionally well. You can, of course, continue to use whole grain, but I just use organic white “bread” flour for days 2 through 6, less costly.  You can also feed with organic all-purpose flour, but I’ve had much better luck with getting the starter stronger, faster, starting off with the wholegrain the first day, and using bread flour for the remaining. UP to YOU. You can always mix in a little whole grain with the white as well if your starter looks like it needs a boost. 
    3. WATER: Sometimes chlorine in tap water can inhibit the growth of your starter. Some people leave tap water out, in an open container overnight to allow some of the chlorine to evaporate.  Using lukewarm water helps fermentation to start faster. Try Mineral water, like Perrier, it seems to work wonders too! Sometimes bottled water can be overly sterile- so using mineral water (carbonated is OK) is a good option.
    4. HYDRATION: Hydration refers to the ratio of water to flour in terms of weight. It is a ratio. For starter, this is typically at 100% hydration.  Meaning if you use 120 grams of water, use 120 grams of flour. This roughly translates to 1 heaping cup of flour and 1/2 cup water.  Feel free to weigh instead of measure if you want to be more precise or want to familiarize yourself with the consistency. It’s nice to do this the first time to get a feel for it.
    5. STORING AND FEEDING: When your starter is kept cold, like in the fridge, you don’t need to feed it as often- only once a week. If you keep it out on the counter, you’ll need to feed it 2 x daily. Cold slows down the fermentation, and heat speeds it up.
    6. USING: When you need to use your starter for baking bread, feed it 4-8 hours before making bread dough, using it right at peak height or slightly after (even better).
    7. Do I REALLY have to discard my starter? YES. I know it seems wasteful- but while you are building your starter, during the first week, it is the simplest easiest, fastest and most economical way to create healthy a starter. This is because you always have to feed it 2 times its volume!!! If you keep the 1 1/2 cups starter, you would have to feed it 3 cups (instead of keeping just a 1/2 cup and only feeding it ONE cup). Get it? 😉 Doing this will shorten the fermentation process, require less flour in the long run, and create a stronger starter. Once the starter is “established” after the first week- then you don’t need to discard it but can use it in bread baking, pizza dough, scones, biscuits, waffles, sourdough buns, etc.,- or give it to a friend.  

Signs of Hunger:

The photo above was taken after the starter was fed,  peaked 4 hours later (reached its highest), and now is” hungry” again. The perfect time to use it in bread! See the downward slide marks on the jar. Again, pay attention to these- your starter is telling you what it needs. You just have to learn how to see it.

Ingredients

Scale

Instructions

    1. Day 1: Starting in the morning or at night, using a wide-mouth quart jar or Crock or Glass Measuring Cup mix 1 cup whole grain flour (120 grams) with 1/2 cup (120 grams) filtered water using a fork making sure you’ve incorporated all the dry flour.  For your first measuring – it is a good idea to weigh the flour, using a kitchen scale so you get an idea of how thick it should feel. It should be like a thick paste. Thick like peanut butter. If you need to add a little more water to incorporate the flour, that is OK, but be precise with the flour. Place the lid on top (using the Weck jar is really handy here) or a damp towel to keep moisture in, or plastic wrap- and let sit at room temperature (70-80 degrees) on the kitchen counter for 24-48 hours, or until you see some bubbling. If you are not sure how warm it is, use a kitchen thermometer and check it a few hours later. See notes for TEMPERATURE.
    2. Day 2: After the first 24 hours, you may or may not see a bit of bubbling. I prefer to let this rest until I see a tiny bit of activity (bubbles) and sometimes this takes 36 or up to 48 hours.  So start “day 2”, when you see a little bit of bubbing. Discard all but 1/2 cup (136 grams) of the starter. (See notes for discard).  Add to the remainder, 1 cup of white bread flour, (120 grams), spooned and leveled,  and 1/2 cup filtered water (120 grams), mixing well with a fork. Place the lid on loosely again and allow the mixture to sit at room temperature (70-80F)  for another 24 hours.
    3. Day 3: By the third day, you should definitely see some bubbling- and if not, let it go a bit longer. Depending on how warm your house is and how active your starter, you may need to begin feeding more often, or even move to two feedings a day roughly 12 hours apart, like in the morning and at night. In a nutshell, you want to feed the starter only after it has peaked (metabolized all the flour from the last feeding) and has started sinking down or gets liquidy- this is when it is hungry! This might be 12 hours, it might be 14, it might be 18, or 24, depending on the temp in your house. In very warm climates it may only be 8 hours.  It is better to underfeed rather than overfeed here. For each feeding, like before, discard all but 1/2 cup of the STARTER (keeping roughly  ½-cup of starter in the jar -4 ounces or 136 grams) Add 1 cup Bread Flour  (spooned and leveled) and 1/2 cup water to the 1/2 cup starter and let this rest at room temperature for 12-24 hours or until the starter looks “hungry” again before repeating.
    4. Day 4: Feed 1-2 times,  discarding all but 1/2 cup of starter EACH TIME. Feed 1 cup bread flour, 1/2 cup water.  Look for the hunger signs. Hopefully, you’ll begin to see some rising and falling. It’s helpful to put the starter in a clean jar and mark the beginning level (with sharpie, string or rubber band) so you can easily see this. ***If for some reason your starter looks like it is still rising at the time of second feeding (at night) and there is no evidence it has fallen or no slide marks, it is still “eating” so  skip this feeding and feed first thing in the morning. AGAIN, Feeding it when it is  “not hungry” will basically dilute all the growing yeast and make it lethargic. Better to starve than overfeed.  
    5. Day 5: Feed again, 1-2 times, roughly 12 hours apart, or when hungry,  discarding all but a 1/2 cup the starter EACH TIME. 1 cup bread flour, 1/2 cup lukewarm water. The starter should look active, bubbling, rising, sliding down, hopefully, close to doubling in size. (If not, repeat this day until starter doubles in size within 8-12 hours of feeding- and read the troubleshooting section.) 
    6. DAY 6:  Give it one last feeding. Discard all but a 1/3 cup. Add 1 cup flour ( 120 grams) and 1/2 cup water, and place it in a clean jar so you can see the action clearly.  You can use a sharpie or place a rubber band around the jar to mark the beginning level. The starter should hopefully double in volume within 6 hours of feeding.  When it peaks, DO THE FLOAT TEST: To test the starter, place a teaspoon of starter (just from the top, while it is peaking, don’t stir it down) in a glass full of water, it should hopefully float. If it does, you can make sourdough bread. Tonight! Let the starter keep resting at room temperature or a few more hours allowing it to fully metabolize the flour, perhaps sinking a little before making your dough. You want to make dough with slightly hungry starter. Place the remaining starter in the fridge and feed it in a week. You’ll have enough stater to make one more sourdough loaf during the week, and still have enough to feed.  If you want to wait to make bread until later in the week place starter in the fridge. Be sure to feed it in 7 days. Read maintenance section.
    7. At this point, if your starter does not double in size don’t give up! Often it just takes longer, sometimes up to two weeks, especially if it’s cold.  Continue feeding one-two times a day (only when hungry) for a few more days, until you see a visible rise and fall. Read the troubleshooting section. If you need to take a break, just put it in the fridge and try it again up to a week later. Don’t toss it- if there are bubbles, it is still alive.
    8. This batch of starter will make two loaves of bread with enough left over to feed for the following week.

TROUBLESHOOTING:  

  • STALLING:  It is typical to see a “stall” on day 4 or 5. If your starter is not rising but there is evidence of hunger (liquid at the top) try 3 things: substitute 1/4 cup whole grain flour (add to ¾ cup white bread flour) on your next feeding. Try using mineral water like San Pellegrino instead of water.  Stir the starter a couple hours after feeding to allow wild yeast from the room to get in there.
  • SMELL: Starter should smell slightly sweet and tangy, and not off or “bad”.  To me, it smells like a wet horse;)  If it smells VERY unpleasant, you may have used an unclean jar, or an unclean utensil, or somehow introduced another foreign bacteria. I would start over.
  • TOO MUCH ACTION: if your starter overflows from the jar, this is a good sign,(not bad) it is alive and active. This often happens in warm climates. You’ll need to feed it more often or find a cooler spot. Even if it floats on day 2-3, please keep feeding it the full 6 days before using it to make bread. It will add more flavor and complexity.
  • CONSISTENCY: Thick or Thin? If you have been careful about measuring feedings, but are not seeing rising or falling, another way to tell what stage of your starter is in is to look at the consistency. If the starter seems really thick, it is still “digesting”. If it seems loose or runny or liquidy, (to the point where you can pour it out of the jar) it has digested all the flour and is now “hungry”. It loosens up as it metabolizes the flour. So even if you don’t see rising or falling, look for consistency to give you clues.
  • DO NOT overfeed. For example, maybe, feeding 2 x day at 12-hour intervals is too often. You want to feed after the starter has peaked, then deflated a little or is runny (see photo above- you’ll see some slide marks on the jar) and this tells you that it is hungry. If you feed the starter before it has had a chance to metabolize (or eat) all the flour and then you discard part, and feed it again, you are actually diluting all that amazing yeast. Get it? So it’s all about watching your starter in your home. There are lots of variables here. Just be patient, pay attention and watch. This is a living thing- it doesn’t care about time schedules and recipes or what it “should” do. It will “eat” when it is “hungry” and sometimes it likes to eat slowly.
  • It may take longer than 6 days in colder environments. Use a kitchen thermometer and take its temp. Is it under 65F? Find a place where it can be warm.  Or use lukewarm water when mixing. Place it  in the oven with the light on overnight. (Not in direct sunlight) or above the fridge, or on the stovetop. Sometimes if cold,  it takes 10-12 days. Be patient, keep going. If it is doing absolutely nothing, leave it out on the counter for 24-48 hours and see what happens. If you see bubbles, it is alive and can be coaxed. If you run out of flour or need a break, don’t just toss it, put it in the fridge and see if you can get it going a few days or up to a week or two later.
  • ACIDITY: If you still can’t get that starter going, some people recommend subbing pineapple juice for the water for one feeding- raising the acidity level. My good friend just tried this and it got hers going.
  • LIQUID: If you see any liquid at the top of your starter, it means your starter is hungry. So, yes it’s still alive which is a good thing! You can stir the liquid in, or pour the liquid out, either way, but feed it! This may be a sign that you may need to feed it more often than you are.
  • MOLD: if you see any discoloring or mold on the surface, the starter was probably contaminated. If it is only on the surface, you could salvage it. Scrape it off, save 1/2 cup of the underneath starter, and keep going. Feed, smell, use your best judgment.
  • FLOAT TEST: If your starter is consistently rising and falling and it is has been over 8 days, but still doesn’t pass the float test, try baking a loaf of bread anyway.  Remember, use hungry starter when mixing up the dough.

MAINTENANCE:

  1. REFRIGERATE & FEED AT LEAST ONCE A WEEK: Pick a scheduled day and try to stick with it, always reserving 1/2 cup starter (130 grams) and feeding it 1 cup flour  (120 grams) and 1/2 cup water (120 grams). Discard the remaining, or give it away, or keep the discard in a separate container to use in waffles, pancakes, sourdough buns, banana bread, biscuits, etc. I usually don’t feed the discard unless giving away.
  2. If you forget to feed it one or two weeks in a row, it is most likely OK, just feed it 1-2 x day for 1-2 days in a row to revive it (keeping it out on the counter) until bubbly and active.  I’ve left my starter for a month on vacation (in the fridge) without feeding and simply revived it by feeding it 3 days in a row, 2 x day. It’s actually kind of hard to kill. You can also freeze it for longer storage.
  3. If you find yourself wanting to bake more often than once a week, you can keep it out and feed it 1-2 times daily. Or if baking every few days, you can pull it out of the fridge, feed it 8-10 hours before using, leaving it out, use what you need while it is peaking, then put it back in the fridge that evening. Do the same thing a few days later when ready to use it again. So this would be feeding 2-3 times a week, best if baking 2-3 times a week.


Notes

  1. TEMPERATURE: The colder your home, the longer it will take for the starter to grow and become active (bubbles). Find a warm spot (70-80 degrees) for the best results. On the stovetop, with the light turned on, or on top of the fridge. Or in the oven with the light on. On top of a heating pad (set to low) with a towel in between). You can still make the starter in a colder home, it will just take longer- even up to 2 weeks.
  2. FLOUR: Always try to start the batch by using organic, freshly milled whole-grain flour (wheat or rye) because it has more wild yeast in it than All-Purpose or white flour and will get it active and growing sooner. You can, of course, continue to use whole grain, but I’ve had the best luck using organic “bread” flour for days 2 through 6. People have made a sourdough starter with All-Purpose flour- but personally, this has never worked for me– there are fewer nutrients and wild yeasts in the flour and results in a very lethargic starter. If it is your only option, try mixing in 2+ tablespoons of whole-grain (wheat or rye) with the AP flour per feeding. Feel free to use different flours or mix different flours together. It is OK to use all-purpose flour if in a pinch, but using it repeatedly will result in sad starter.
  3. WATER: I usually use tap water -but sometimes the chlorine in tap water can inhibit the growth of your starter. Lukewarm water helps fermentation to start faster. Sterilized bottled water is often overly sterile, and can also inhibit. Mineral water, like Perrier (carbonated is OK) can sometimes work miracles.
  4. HYDRATION: Hydration refers to the ratio of water to flour in terms of weight. It is a ratio. The starter is typically at 100% hydration- meaning equal parts flour and water, in terms of weight. So if you use 120 grams of water, use 120 grams of flour. This roughly translates to 1 cup of flour and 1/2 cup water.  Feel free to weigh instead of measure if you want to be more precise, or want to familiarize yourself with the consistency you are aiming for. If using whole grain flours (which tend to be “thirstier”) and your starter seems very thick, it is totally OK to add more water to thin it a bit. I intentionally keep the hydration a little lower here (a thicker starter) so you can more clearly see the rise and fall “action” in the jar.
  5. STORING AND FEEDING: When your starter is kept cold, in the fridge, you don’t need to feed it as often- only once a week. Feel free to feed it “cold”, and put it right back in the fridge if you like. If you keep it out on the counter, you’ll likely need to feed it 1-2 x daily (or just watch and feed only when hungry).   Cold slows down the fermentation, heat speeds it up.
  6. USING: When you need to use your starter for baking bread, feed it 10-12 hours before making bread dough, using it after its peak height. For a more “sour” flavored bread, use the starter straight from the fridge, 3-6 days after feeding. The starter gets more sour tasting the longer it goes without feeding. Feeding the starter the same day as making bread will produce a milder sourdough flavor.
  7. Do I REALLY have to discard my starter? BASICALLY YES. I know it seems wasteful- but while you are building your starter, during the first week, it is the simplest, easiest, fastest, and most economical way to create healthy a starter. (Or save it separately -in the fridge- and use it in Pancakes, Waffles, Buns, or Biscuits. )  This is because you always have to feed it 2 times its volume in flour.   For example-if you kept all the 1 1/2 cups of starter, you would have to feed it 3 cups of flour (instead of keeping just a 1/2 cup and only feeding it ONE cup).  Doing this will shorten the fermentation process, require less flour in the long run, and create a stronger starter. Once your starter is “established” after the first week- then you can give it away to friends, use it in pizza dough, banana bread, waffles, pancakes, buns, etc) or give it to a friend.   If you would like to save your “discard” during the first week – use it as you would flour and water, not expecting any rise. 
  8. HOW TO USE YOUR SOURDOUGH STARTER/Discard : 
    1. No-Knead Overnight Sourdough Bread (only if it passes the two “tests”)
    2. Overnight Sourdough Waffles 
    3. Sourdough Pancakes
    4. Sourdough Scones 
    5. Sourdough Biscuits
    6. No-Knead Sourdough Bread – only after day 6
    7. Vegan Banana Bread 
    8. Sourdough buns

    Save the sourdough “discard” in a separate container in the fridge.

  1. Help! After the first 3 days of doing well, my starter seems to have just… stopped. I’m on day 5, probably 4 hours since feeding and it hasn’t risen, just a couple of bubbles on the top. It didn’t rise yesterday either. Should I start over?

    1. If it is bubbling, just be patient, it is still alive. Look at troubleshooting section for clues.

  2. Hi!
    I am currently on day 11 and my starter does not quite double in size. However it passes the float test. Can I still make bread? I have been using King Arthur All purpose flour mixing in whole wheat flower every now and then. What should I do to get the growth needed?

    1. I think you should just give it a try and bake. Or if you want, let the starter get really hungry, then try feeding with mostly whole wheat. But I bet it is fine now. Using AP flour doesnt give it the same rise but it sounds like it is fine!

  3. So I started this about 5 days ago and on the 2nd and 3rd day it looked good and smelled good – sweet and tangy. It still looks right but the smell has gotten really strong and not sure if there is something wrong with it. I have had a starter before and don’t remember this strong smell. How can I tell if there is something wrong with it? It is growing and everything like it should be ?

    1. When you say strong- do mean bad? The smell is likely from fermentation. Which yes, can smell strong, especially when hungry. Was your jar clean?

      1. It does smell like strong fermentation. It was clean before I started the whole process. I understood that I shouldn’t switch jars until the starter was completed – after like 6 days. Should I have been washing every time i fed it?

        1. You can switch jars and clean jars. The video may help clarify. Maybe your starter is just very active and happy?

  4. HELP!

    Hi! I was feeding one of my starters last night and wasn’t paying attention. I forgot to discard half of it out before I added flour and water. I only realized after I started mixing and questioned why it was so thick… Suggestions on how to proceed?

    This morning it appears to be really bubbly 1-2 inches from the top but the further down the jar goes, it’s less bubbly. They had been in my fridge for almost a week since the last feeding, so I’m sure they are just slower to eat and I was planning on feeding the, again later today, but I’m not sure what to do with the starter that I forgot to discard.






    1. So just wait until it looks hungry- discard all but 1/2 cup and feed like normal. Basically, at your last feeding, you only fed it a snack. 🙂

  5. Hi, I am on day 17. Starter won’t float. Since day 10, starter gets bubbly/foamy after about 8-10 hours1, then sinks very slightly. I don’t see skid marks. I wait (marking jar with post-it flags) another 1-2 to make sure it’s finished growing and then re-feed. I’m using most white whole wheat and whole wheat flour. I also tried bread flour and got less activity. Thermometer on counter says 70-76 degrees. I’m weighing and measuring flour. Per advise to another reader about starter not floating, I did risk using it for bread but the dough would not rise. I’m stumped. Any ideas?

    1. Hummm, interesting! Why don’t you skip a feeding- like let it go 24-36 hours, let it very hungry before feeding the next time and see what happens.

      1. Well, I finally succeeded, on Day 27. It never did float but it was consistently doubling in about 4 hours. I’m wondering if the problem I had at the proofing stage a few weeks ago was due to the room being too warm? Thanks for your help! (I also made your vegan banana bread recipe!)

  6. I started with whole wheat flour on day one and then started using organic type 80 wheat flour. It is not rising but bubbling and seems quite thin. Smells good but should I change flours? I’m also using distilled water

    1. As long as you are weighing the flour it should be ok. You can use a little less water if you want? But keep flour weight the same.

    2. It’s going crazy after I decreased the water to 1/3 cup!! Now I’ll let this continue for a few days and do a float test. But my question is how much water should I use when I actually start baking?

      1. Just use what you are using. 🙂 1/3 cup is fine if the consistency looks similar to video. Or if you want to increase it that is fine too.

  7. I finally decided to go ahead and do my own starter. Today is day 2, I fed it in the morning, and less than 12 hours later it doubled its size, what do I do? It’s about to reach my containers capacity and I still have to leave it overnight and I am getting anxious it will overflow or get ruined. What do I do? I wasn’t expecting this much activity and I did discarded the leftover following the right amounts.






    1. This is not a problem- this is a GREAT sign. Just put a plate under it. It is OK, it just means your starter is happy and alive!

      1. Perfect! Now I have a second issue 🤣 I am not sure ig in the feed from the morning I put 1 cup or 1/2 of flour. It looks mlre liquidy than normal and It didn’t rise much. I see it deflated just a bit. Should I go ahead with the second feed?

  8. I am trying to make this starter but only have access to all purpose flour and bread flour (stores are sold out of the other). Day 1 I used All Purpose flour and Day 2 Bread Flour. It’s been 9 hours since taking the 1/2 cup starter and adding the water and bread flour and the starter is rising and rising. It is about to overflow the jar. Do you know what is going on?

    1. Have you watched the video- it may help clarify. It is doing exactly what it needs to do. All is well. 🙂

      1. All is good with the starter, yeah! It passed the float test. Now my question is when I feed it once a week, removing it from the refrigerator, do I leave it on the counter for the day to see it rise and sink before putting it back in the refrigerator or do you feed it and put it right into the refrigerator?

  9. Hi! I’m on Day 2 (just made the starter yesterday), and a little bit of liquid has separated out. There are bubbles, but only in the liquid. Is this normal, or did I do something wrong? Should I feed it tonight and continue the recipe?

    Thank you!

  10. Hello, I live in Paris. I have made the sourdough starter , it worked perfectly. I have made the bread. Could not beleive my eyes when I saw the bread rising and being perfectly cooked , not at all dense, but just right. Your explanations are generous, clear, to the point . You take your time to go at length taking us step by step through the recipe. Thank you so much. Would you by any chance have a recipe for sourdough “Brioche”?






      1. Thank you so much. Meanwhile will try the banana cake.
        Have a lovely week end
        Cheers from Paris
        Nadine






  11. We used the recipe and it worked perfect the first time , we were able to make bread. We store it in the fridge for a couple of days, then we took it out fed it, and it is doubling its size beautifully every 4 hours, but when we try to do the float test it sinks…
    What could be happening?
    Thank you for your help






    1. Adriana- I don’t think it needs to continue to float to make bread- at least that is what I keep hearing from readers. Just go ahead and bake with it.

  12. I’ll on day 3 and truly appreciate your direct instructions. Looking forward to bread made at home. Thank you






  13. Sylvia I just started my starter today. i did not have a kitchen scale so I use the cup measurements. I used Bobs Mill Rye Flour as a first time only starter flour. I did shifted the flour prior to filling the cup measurement. Somehow my mixer was too thick and lumpy(such that it stick to the spatula) so i added more water a little at a time to match the consistency of what i saw in your video and other videos. Now i am not sure if the measurements worked or not. Should i start again or give it a try until 24 hours to see. Is it because i used all rye flour? i read somewhere that rye flour starter combined with bread flour works good plus i had very little leftover to use up.

      1. Sylvia I am on day 3 today. On day 2 it was great with a lot of bubbles and doubled. I fed it bread flour and now 24 hours later it is not showing a lot of activity but some bubbles only it is not rising. Do i skip a feeding today and see what happens in the morning? yesterday was a unusual hot day and today it is normal so that could be it too

        1. If it seems liquidy, go ahead and feed it- like, will it pour out from the jar? If so feed. If it is stil kind of thick maybe give it overnight.

          1. Everything went well. Thanks for this detailed recipe. Made pancakes from the discard, made one bread using bread machine recipe and another one using oven recipe. Obviously the oven made was very good and given everyone liked it a lot I may be baking it often 🙂
            My question is on the starter that I have saved in the refrigerator. I am a little confused so need help. Let’s say i want to bulk rise the bread at night so when should I remove that starter and feed? Please help as I am not sure of this part.






          2. Either feed it that morning, or use unfed starter that has been in your fridge for up to 6 days.

          3. I am actually having the same problem as the person above me. Day 2 my starter doubled in size and then slid down. I fed it day 3, but I couldn’t feed it a second time since it didn’t rise and fall down. Now day 4 I fed it again in the morning even though it didn’t rise and fall down. There were bubbles though, but not liquify. It’s already been 12 hrs on day 4 and the started hasn’t risen at all. I’m not sure what to do 🙁 . I have yet to even start feeding it twice.

          4. Hi Sandra, it is ok if you don’t feed it twice a day. If it doesn’t look hungry, do not feed it. It might be your flour or the temp. Just keep watching your starter, feeding only after it looks hungry (look for the signs). As long as there are bubbles, it is alive. 🙂 Don’t worry too much about the schedule.

  14. I have 2 different brands of whole wheat flour and both measure less than 1 cup for 120 grams. Should I stick with 120 grams or the heaping cup?

  15. Sylvia, thank you for the wonderful site. I began a starter using a cup of Grand Traverse Hard Red Spring Wheat on Sunday. Following your instructions, I substituted bread flour in on the second day, and on the third day, my starter blew up! Using the recommended glass container you recommended, my starter was oozing out of the top like a yeast volcano! I dialed the feedings down to 1/2 cup flour & 1/4 cup water, and it still exceeds the volume of the jar,…this is now my third day,…weather has been a bit warm here in Michigan of late, and I’ve taken to putting “Doug” in the refrigerator to ‘chill.’ My question is this…do I keep feeding the starter for the next 3-4 days, twice daily? Will Doug proceed normally in the fridge? How will I know my starter is ready to use? It’s certainly very active!






    1. Hi Kevin- you are lucky to have such active starter! I would still feed for the full 6 days, just to make sure it is strong. After day 6 see if it floats.

  16. i love the videos and exact directions in this recipe. I am on day 7 and i just passed the float test!!! My question is i don’t want to make the sourdough bread until this evening because i don’t want it to over proof over night. Should i put my starter in the fridge for a few hours and start the bread in a few hours or just leave it out until i make the bread? it has already peaked and started to slide down.
    THANK YOU AND WISH ME LUCK!






  17. This is the best guide for beginners I’ve found. The combo of the video and detailed directions are incredibly helpful. I’m now ready to start tomorrow morning. One question I’m struggling with is regarding the refrigerator maintenance stage- Do I really discard ALL but 1/2 cup of the starter then feed it OR can I simply take out what I plan to use and replace it with equal parts water and flour without discarding so much of it?

    If the latter is possible, then what are some of the pros and cons over doing it that way vs discarding/using all but 1/2 cup of the starter?






    1. When it is time to feed- always Use or Discard all but 1/2 cup (feel free to use the discard) but in the jar, you only want to keep a 1/2 cup of starter before feeding it. Does that make sense?

      1. Yes and Ty- I’m on day 2 now. I am using King Arthur’s white whole flour. It doubled overnight in size on day 1. Today it almost tripled Size in less than 8 hours and is starting to go down. My kitchen is in the 70-80 range. I’m about to give it a 2nd feeding because it seems to be taking rather quickly. Is this okay? how does its progression alter when I can use it for bread?

        I plan to switch to bread flour as soon as it comes. It’s been hard to find locally and I just ordered some last night.

        TY for being so responsive and helpful!






        1. Yes, just feed it when it looks hungry. I would still wait till day 6 to bake though. 🙂

  18. I am following your recipe, so far everything is working great! But today I forgot to discard half of the starter before feeding it.. Did I kill it now? 🙁

    1. No Tess, you didn’t kill it. It will probably get hungry faster, since overall it had less food. Just watch it.

  19. My (first) starter passed the float test and I have just added the water / starter to the flour. Followed the directions to incorporate the liquid with the dry ingredients, but
    the mixture seems dry., not a shaggy ball as directions describe. I’ve not altered it this time, don’t want to change any variables until I see how it goes. But does this seem too dry? Would adding more water be a mistake?or is that what I should have done? Directions call for it to sit loosely covered with plastic wrap for 10-14 hours, so will see how it looks in the morning.

    1. Hi Nancy- are you referring to the bread dough recipe? It will seem dry at night and loosen up in the morning.

  20. I’m on day four and though my starter seems happy I’m realizing I may have made a mistake.. I’ve been using a jar with a lid instead of a towel, Saran Wrap, etc.. is this a bad thing? Or is it ok? Should I just use a towel, or Saran Wrap? Do I need to start over? TIA!






  21. Just made my first loaf following your instructions. I have impressed my family. Thank you for your brilliant video, I have been following it for 8 days.






  22. I am in the midst of working on my starter, and it rises BEAUTIFULLY, is bubbling, and actually overflowing! I have never gotten the deflation, and slide down marks. What should I do??






    1. I just tried a spoonful in a bowl of water and it is totally floating!! I am wondering, if even though I never saw large slide marks (small amount in the beginning), am I still ready to make bread!?

    2. Maybe just give it a little more time to fully peak. You want it hungry before you feed it again. 🙂

      1. Thank you for the info and fast reply. I really appreciate your feedback!!!
        It is half way below the original level. If it does not rise in a week, shall I throw it out?
        Thanks!

        1. Maybe- just watch for any activity. Even just bubbles. Bubbles means it is alive and you can coax it.

  23. Hi!
    My crust was chewy. Did I under cook it? The bread was fine!
    I am doing the feed 1x week with it in refrig. The starter actually dropped after the first 48 hrs. Do I need to feed already?
    Thanks!






    1. I would feed it if it looks hungry. I wonder if your fridge is warmer than mine. Mine is at 41F and starter doesn’t drop until day 5-6. Chewy crust: as in it is soft, or too crusty? Sorry, not sure what you mean. You can play with leaving the lid on longer.
