How To Revive Sourdough Starter

Don’t throw away that neglected starter sitting in your fridge, revive your sourdough starter and bring it back to bubbly, active life with this simple feeding schedule and troubleshooting guide. Even starters forgotten for months can be brought back from the brink.

Craving The Details?

What it is: Reviving sourdough starter means feeding a mature starter that has been dormant in the refrigerator until the yeast and bacteria become active again.

Why you’ll love it: You don’t need to start over just because your starter has been sitting in the fridge for weeks or months.

How to do it: Remove the starter from the fridge, inspect it carefully, then feed a small amount equal weights of flour and water, let it ferment, repeating the process until it reliably rises.

Raise your hand if this sounds familiar…

You’re cleaning the fridge mid-September and you come across the sourdough starter you haven’t seen since May when the sunshine was calling and the shorts came out.

“Oh my god. FRED!”

Don’t worry, you can revive a sourdough starter that’s been long neglected in the fridge! Even if you neglected it as long as I did…

May 12, 2021 and September 15, 2021:

  • 126 days
  • … or 18 weeks
  • … or 4 months & 3 days

So don’t throw out that old sourdough starter just yet!

This guide to reviving sourdough starter is dedicated to shorts season.

Note: You may hear this called reviving, reactivating, refreshing, restarting, or waking up sourdough starter. In this guide, I’m talking about the same basic process: taking a mature starter that has been dormant in the refrigerator and feeding it until it becomes reliably active again. Amount of feedings and recovery time depend on how long it was unfed.

How Long Has Your Starter Been In The Fridge?

The length of time your starter has been in your fridge unfed will absolutely impact how long the reactivation process takes. Here’s a rough guideline on what to expect.

Time in fridgeWhat to do
A few days to a few weeksBring it to room temp and feed it once, it should show normal activity within 6-12 hours but may need more than one feeding
Several weeks to a couple monthsGive it 1-2 room temperature feedings 12 hours apart, and 1 feed at 24 hours before baking
Several months or longer Follow the full revival process below. Expect it to take 3-5 days
Not sure how long it’s beenFollow the full revival process. Expect it to take 3-5 days
Mold or pink/orange/red streaksDon’t try to revive it, toss your starter and start fresh

Moldy Or Contaminated Sourdough Starter

While almost any starter can be revived, I don’t play with mold or bad bacteria. Fermenting foods takes a little bit of intuition and a little bit of ruthlessness. If something looks, smells, feels, or just could be bad – it finds the garbage quickly!

Look:

If your old starter has any kind of mold, toss that bad boy. Start fresh with my 24-hour starter recipe, and you’ll be just fine.

Once you determine your starter has no mold, look at the hooch – if it has grey or black-ish looking hooch, we’re in business. If the starter or hooch is pink-tinged, it’s straight to the trash bin, do not pass go, do not collect $200.

Smell:

If the starter smells tangy, like vinegar, alcohol or even nail polish remover, that can happen when a starter has gone a long time without feeding. If it has a musty or moldy smell, smells like rotting meat or anything repulsive, toss your starter and start over.

Feel:

Texture alone isn’t a reason to throw out your starter, but it can help to identify contamination. A neglected starter should be thin and liquid, will likely have separation of the starter and hooch, and may have crusted, dried starter around the edges of your container.

Reviving Sourdough Starter

Unfed starter with grey hooch on top and bubble holes in the surface.
  1. Step 1: Remove the unfed sourdough starter from the fridge and allow it to rest at room temperature for 3-4 hours.
Stirring hooch into neglected starter.
  1. Step 2: Look closely at the starter, discard immediately if your starter has mold, a pink/orange/red tinge, or smells musty, as these can be signs of contamination, so I don’t recommend trying to revive it.
    If the starter passes the test, stir in the hooch, or pour it off.
Should I pour off the hooch or stir it in?

There are advocates on both sides of this debate. I prefer to stir it in, because I find (through very unscientific trials) that starters wake up better with the hooch stirred back in. I also believe that it helps keep my hydration percentage correct.

Measuring sourdough starter and adding to a clean jar.
  1. Step 3: In a clean jar or container, mix 50g of the unfed starter with 50g warm water, stir until combined, then add in 50g flour.
Adding water to the sourdough starter before stirring in flour for the first feed.
  1. Step 4: Set aside the fed starter for 12 hours, then feed it again using a fresh clean jar, combine 50g starter, 50g water and 50g flour. Mark the side of your jar with the height of the starter. Watch the starter for signs of activity. It may be a little bit sluggish, but you should start to see a few bubbles here and there.
Adding flour to sourdough starter and water, then mixing until fully combined.
  1. Step 5: If the starter is close to doubling within 12 hours, wait 24 hours before feeding again. If the starter is not close to doubling by 12 hours later, feed it again – and repeat until the starter doubles within 12 hours, then reduce to a once every 24 hour feeding period.
Revived starter in fresh jar after feeding.
  1. Step 6: Once the starter is revived and doubling regularly, it should be maintained on the counter and fed every 24 hours for 4-5 days. This will help get your starter healthy again before it’s placed back in the fridge.
  2. Step 7: Feed your starter weekly or bi-weekly once it’s in the fridge to keep it healthy and active.
How Do I Know If My Starter Is Ready To Bake With?
  • It rises predictably after feeding
  • It at least doubles within the expected timeframe for your feeding ratio and temperature
  • It has bubbles throughout, not just on the surface
  • It develops a domed top
  • It smells pleasantly fermented
  • It can repeat that same performance after consecutive feedings.

It’s Not Just You!

Expert Tips

  • Don’t panic, feed it. A neglected starter can look rough after a long fridge nap, but ugly doesn’t mean dead. If there’s no mold or obvious contamination, give that fermenty baby some fresh flour, water, and a little time. There’s a very good chance you’ll be back to baking before you know it.
  • Give it the once over. Before you start feeding, take a critical look at your starter. Hooch, separation, a strong fermented smell and generally sad appearance can all happen when a starter has been neglected. Mold or obvious spoilage is a different story. If something looks genuinely off, check my guide to figure out if your sourdough starter has gone bad and know when it’s time to let go.
  • Stick with the usual. Try to feed your starter with the flour it was raised on. I like to keep it familiar when waking up sourdough starter. If you’ve always fed it bread flour, keep feeding it bread flour. The same goes for whole wheat, whole grain, all purpose, rye flour, or gluten-free. No need for a surprise party when your starter is already having a rough day.
  • Mark the jar. Don’t always trust your eyes to tell you if your starter rose 25, 50 or 100%. A rubber band, a piece of tape, a hair tie, or a dry erase marker can make the rise much easier to track.

Why This Process Works

Yeast and bacteria slow way down. In a cold fridge, with no fresh food, there’s nothing to trigger the yeast and bacteria to feed and multiply, so they “hibernate”. Once the starter is refreshed with water and flour and moved to a warmer location, the microbes get the signal, loud and clear!

1:1:1 ratio lets microbes thrive. An unfed starter is basically starving, over time the bacteria and yeast consume the proteins and starches, leaving behind a sour, acidic environment. By using a 1:1:1 feeding ratio, you’re adding extra food and diluting the acidic environment. Over the first few re-fresh feedings you’re establishing a healthy balance.

Time is required. A 3-5 day window is pretty standard for reactivating sourdough starter. It takes time to wake up dormant starters, multiply enough to be noticeable and produce the bubbles and rise that tell you that it’s re-activated.

Reactivating Sourdough Starter FAQs

My starter doubled after just one feeding, can I bake with it now?

It depends on how neglected your starter was. If it doubled after a single feeding, it was probably in reasonably good shape. However, I do find that after a prolonged time without feeding, starters can double in the jar easily but lack the leavening power to raise bread.
I’ve done this in the past, and have been disappointed each time because my loaf was dense, flat, and bland.
My recommendation: Give it at least a second feed before baking, based on my experience.

Do I really need to discard, or can I just keep adding to the starter?

You’ll need to discard all but 50g of the starter. The discarding portion is very important, as it allows you to feed the starter with the correct ratio without growing your starter exponentially, and it helps to quickly reduce the acidity in the starter environment.

What if my starter has hooch on top – is it ruined?

Hooch (that grey liquid on top) is a sign that your starter is hungry, not that its bad. If it’s grey or smells like vinegar, that’s totally normal. Just keep feeding it on your regular schedule and it will bounce back.

What happens if you leave a sourdough starter in the fridge for too long?

The starter will eventually consume most of the proteins and starch in the starter then settle into a dormancy. The starter will likely generate a layer of hooch (grey liquid on top of the starter) and the environment will become more acidic. As long as the starter is not contaminated with mold or bacteria, it should be able to be reactivated.

How long can a sourdough starter actually stay dormant and be revived?

You found your starter in the back of the fridge and have no idea when it was last fed. Could it be too old to save? Probably not!
Here’s what real readers have experienced:
* 1 year neglect: Michele left her starter in the fridge for almost a year without feeding it. She followed my revival process and it came back to life!
*5 year neglect: Lise had a COVID lockdown starter that sat untouched in her fridge for 5 years. She was skeptical, but followed the revival steps anyways. It took about a week, but her starter came back to life, happy and bubbly!
*3+ years frozen: Gary pulled a sourdough starter out of his freezer that had been there more than 3 years. His first few feedings were slow, but stuck with it and the starter came back.
What these experiences show: Starters can sometimes recover after surprisingly long periods of cold storage. Recovery time and success will vary depending on the condition of the starter, storage environment and how it responds to feeding.

Sourdough Starter Feeding + Maintenance

There’s a lot to sourdough, but there’s also not a lot to sourdough! One of the things you’ll have to decide is how often you’ll be baking. For me, in the fall and winter months, I bake much much more frequently. So I actually use different sourdough feeding and maintenance methods depending on the time of year.

Daily to Bi-weekly Baker

  • you’ll want to keep your starter at room temperature and feed it daily. This will keep it warm and active whenever you’re ready for it!
  • feed it around every 24 hours. You can play with the feeding schedule a bit, once you get to know your starter and how hungry it is. The starter should be fed after the culture doubles in size and deflates.

Weekly or Less Frequent

  • keep your sourdough in the fridge! This slows down the fermentation time considerably and allows you to feed your sourdough only once a week.
  • simply remove it from the fridge, then stir and feed, and rest for 12-24 hours at room temperature before starting with your recipe. Once the fed starter doubles, it is ready to use!

Want To Take A Longer Break?

Instead of leaving your starter unfed in the fridge indefinitely, you can freeze your starter or dehydrate sourdough starter for a long-term backup. These starter storage methods give you a safer “insurance policy” than relying on the jar in the back of the fridge.

Instructions
 

  1. Remove the unfed sourdough starter from the fridge and allow it to rest at room temperature for 3-4 hours.
  2. Look closely at the starter, discard immediately if your starter has mold, a pink/orange/red tinge, or smells musty, as these can be signs of contamination, so I don't recommend trying to revive it.
  3. If the starter passes the test, stir in the hooch, or pour it off. I prefer to stir it back in, but it can be poured off too.
  4. In a clean jar or container, mix 50g of the unfed starter with 50g warm water, stir until combined, then add in 50g flour.
  5. Set aside the fed starter for 12 hours, then feed it again using a fresh clean jar, combine 50g starter, 50g water and 50g flour. Mark the side of your jar with the height of the starter.
  6. Watch the starter for signs of activity. It may be a little bit sluggish, but you should start to see a few bubbles here and there.
  7. If the starter is close to doubling within 12 hours, wait 24 hours before feeding again. If the starter is not close to doubling within 12 hours, feed it again 12 hours after the initial feed- and repeat until the starter doubles within 12 hours, then reduce to a once every 24 hour feeding period.
  8. Once the starter is revived and doubling regularly, it should be maintained on the counter and fed every 24 hours for 4-5 days. This will help get your starter healthy again before it's placed back in the fridge.
  9. Feed your starter weekly or bi-weekly once it's in the fridge to keep it healthy and active.

    Nice article Ally. I bake once a week, about every 5 or 6 days, one loaf. so I have two starters in the refridgerator which gets rotated every two weeks. take it out the night before feed it a well rounded teaspoon of rye flour, next morning give it the 1:1:1 ratio three to four hours later more than doubled and ready to make bread dough. I use an old English sourdough recipe. 500 grams of flour / 290 grams of water / 200 grams of starter / 10 grams of sea salt …usually bake the same day, always makes a good loaf of bread.

  2. Hi Ally!
    I just finished reading all the directions and the comments below. I have a refrigerated starter that has been in the back for probably six months. I came across your post and thought I would try to revive mine. It had some gray hooch and was still pretty thin. I took out the 50g of starter (my teacher calls it the mother) and using a clean jar, added the 50g of water and then 50g of flour. I also left my mother out on the counter for a few hours and took a look at it. Still looked then and somewhat bubbly, so I added the same ingredients to it and put it back in the fridge to feed every two weeks. Is this wrong? Is my mother supposed to be thrown out? I have always kept her in the fridge until the next bake and always added some to it before refrigeration. I have done only two feedings so far and no luck but will just keep adding to a new jar with each feeding.

    1. Hey Nancy, there are lots of ways of keeping a starter and many bakers use the same process as you, where you take portions off the mother and feed it to bake (this is known as a levain), and many people do like I do – keep small quantities of one starter and feed it sufficiently to use some to bake and keep some to continue the process. You’ve been using your method for a while and if it works, I’d suggest keeping it the same!

      When reviving it can take a few days before you see a lot of activity, depending on the strength of the starter when it went into the fridge and the length of time it was in the fridge. Please let me know how you make out!

  3. Hi, how long should my starter stay liquidy? It’s been at least a couple days and it’s not doubling and is liquidy…is it no good? Should I just start over?

    1. How long was the starter in the fridge? How strong was it when it went into the fridge? Are you following the feeding routine? If the answers are not too long, strong, and yes, I’d consider a big feed – take 50g of your liquidy starter, feed it 75g water and 100g flour. That should make it thick like peanut butter – then rest overnight before feeding it again.

  4. 5 stars
    My discard was pretty thick in the fridge (not runny like you said it should be). It’s been in there a LONG time, like I don’t remember how long but at least 8 months. Just for science, I left the jar out overnight to let it come to room temperature, then I did your starter feeding method since it didn’t have signs or smells or going bad. It has doubled within 24 hours and has the tiny bubbles. So my question is, since I started it from discard that had gotten really thick, is there any reason I can’t keep feeding it and use it again? Like is there a safety issue?
    Thank you for all of your insights! This has been so helpful!

    1. Hey Deanna, it could have been thick because it was cold!

      Either way, whether you revived discard or starter, they’re the same thing with the same microbiome. The only difference is our perception because one has been fed more recently, long story short, you’re totally safe as long as you didn’t notice any signs of it going bad 🙂

  5. I had some sourdough in my freezer for more than 3 years. Thought I might bring it back to life, so I fed and after 3 feedings now it still hasn’t done much but sit there. Very little action. Then I read somewhere else that chlorine kills starter. I plum forgot about the practice of putting out an open jar of water overnight to let the chlorine dissipate/evaporate before adding it to the starter. It’s been on the counter since I’ve removed it and it’s on the cooler side in the kitchen (65-70 degrees low/high). Do you suppose I should start over or continue to feed this with chlorine free water from now on and see what happens?

    1. Hey Gary, worst case, you’re already 3 days into a new starter if the yeast completely died off in the freezer over that length of time. I wouldn’t start over, I would just continue with what you’ve got going 🙂

    2. @Ally, Hey thanks for the really quick reply. I will continue. So…, is it true that water out of the tap (chlorinated) will kill a starter?

  6. So frustrated and I don’t have all day to search for accurate conversions from grams to cups, etc. Wondering how hard it would be to just put the conversion in parenthesis in the recipe. I am old and the older I get the more I truly understand the old saying, “Old people don’t like change.” It’s frustrating and we don’t have a lot of time left on this earth at this point anyway. I know I sound crabby (I get that way sometimes) but I have lots to do today and “research” wasn’t part of it. I am hoping that it may be correct what I found that 50GM in the starter would be somewhere in the equivalent of 1/4 cup? Going to try and just see how it goes. Please consider revising the recipe! Or just put in a side note. Now I will crawl back in my hole from which I came and try not to “fuss” anymore. Thanks!

    1. Hey Susie, sorry to hear that you find weighing in grams frustrating, and to be honest, until I really gave it a shot, I thought it was annoying too. Now that I am used to it, I actually prefer to bake with weights versus volume, I find it cleaner, easier, and quicker. But the best part is that my results are more consistent.

      I use grams when baking with sourdough because I know that 50g of flour today is the same as 50g of flour tomorrow, and next week, and next year. While using a measuring cup and spoon means I can inadvertently have more or less flour than I want. I do have a youtube video I recorded for my homestead channel that shares how I feed my sourdough starter, along with using my scale and a few tips and tricks along the way. It may inspire you to try it! Here’s the link.

  7. Hi! My neglected starter had some hooch on top and no mold or anything so I started working on feeding it. It’s been three days of feeding with no rising but there have been some bubbles. It wasn’t until after this I read your article and saw that the neglected starter should be thin/liquidy. Mine was definitely not that – it was thick almost like play dough before I added water to it. Can you explain why the thick consistency out of the fridge means that I should toss it?

    1. Hey Emily, the consistency of the starter really depends on how much of the flour the microbes have consumed. So when you first feed it, based on feeding 1:1:1, it’s gonna be really thick like peanut butter and as the microbes eat the starches and good stuff in the flour, the consistency changes as the flour is broken down. This is why hungry starter is runny, and activated starter is kind of snotty, it’s in between thick and pasty and thin and runny.

      Without knowing more about your starter that was in the fridge or your feeding habits, I can’t tell you either way, unfortunately. If you still have the starter, you can allow it to come to room temperature, feed it 50g starter, 50g flour, and 50 g water and rest overnight. An important step in this process is going to be transferring it to a clean new container and marking the sides of the starter jar so you know exactly where it was at the beginning of the feed and will be able to clearly see slide marks on the jar in case it rises when you’re sleeping or at work.

      I’d at least give it 4-5 days of daily 1:1:1 feeding before you write it off. If it’s kind of coming around but not really activating super fast, you can try feeding it 50g starter, 50g water, and 50g whole wheat flour. Sometimes that will give my starter the boost it needs to really get going after a little rest.

  8. Hi,
    Thanks for your great website!
    I started reviving a neglected starter of my own, and also converting a neglected one that was a gift and got lost at the back of the fridge to be a rye starter. However, I’ve just realised I didn’t read the recipe properly – I took 50g of the original starter(s), added 50g flour, 50g water; 12 hours later, added 50g flour, 50g water to the mix not realising I was supposed to discard some, did the same again this morning, and have now realised I should have been doing 50/50/50/discard, not mix+50/50. So, now I’ve done it properly, and have a bowl of 50/50/50 white plus a bowl of discard, and 50/50/50 rye plus discard. It’s all bubbling very nicely! But I’d appreciate your advice – do I need to do anything to rebalance my two starters or just from now on read the recipe properly?! And I have two bowls of fairly runny discard – do I just use this as normal in discard recipes?

    Sorry for the long post and thank you for your thoughts!

    1. Hey Sally, I think you’re fine to be totally honest. Not discarding for the first few feeds after reviving isn’t a huge deal, the starters are great, so no worries there! They make take an extra feed to be at full strength, but it seems you caught it early, so that may not even be a factor. And don’t worry about making a simple mistake, they happen!

      The discard is usually pretty runny once the microbes have eaten all the food in it, but it should be just fine to use in recipes that specify discard. The discard is 50% water and 50% flour, regardless of the texture, if that makes sense.

  9. Thanks for your post , I appreciate the simplicity of your explanation. I have never been able to throw discard away with the high cost of flour (always use it for baking). This time I got 4 jars going and it appears to all be healthy and active so I’m thinking I could use it all in my bread recipe…

  10. Thank you for this informative post! I am trying to revive my starter because it seems too acidic, and I haven’t been able to bake bread successfully. In the past, I was leaving it on the counter and feeding it once a week without discarding. Would this method of reviving a sourdough starter also work well for my case?

    1. You bet, if there are active microbes in your starter, they’ll be happy on this diet! LOL

      Your starter is likely acidic because it’s hungry. In my opinion, (I know you didn’t ask haha) the best feeding routine is 1:1:1 starter, water, flour. I always use 50g each, and then I have about 100g active starter to play with once it’s fully activated – which is perfect for my go to small batch sourdough.

      If you’re wanting to only feed once a week, consider reviving it, then storing it in the fridge, you can slow down the fermentation considerably and reduce the feeds.

  11. Thank you Ally,

    It feels like you have been looking over my shoulder. I am reviving a months old refrigerated starter and it is on a robust doubling schedule. The question involves smell, it has almost none. I’m using King Arthur organic all purpose flour. Am I ok or does this indicate a problem?
    Thanks,
    Fred

    1. Hey Fred,

      If it’s doing it’s thing, no need to worry about the scent! When my starter is cooking along in the winter months, it smells faintly pleasant and not much else.

      I have accidentally left a jar of starter in the cupboard for 2 months, now that’s a smell you don’t want. LOL

  12. I’m a little confused by the directions for reviving. Step 4 says that I take 50g starter, add 50g water and 50g flour and let it rest for 12 hours. Then it says in a clean jar again…so do I remove 50g of starter from the batch done 12 hours prior and then add 50g of water and 50g of flour? Then it would start the hopefully 24 hour feed process?

    1. Yes, exactly. The in a clean jar sentence explains what you should do during that feeding step 🙂 I changed the wording slightly hopefully that makes it more clear!

    2. @Ally, okay. Now that that is cleared up, can I add the step 4 discard to the original? I was going to use that to make something with the discard since I have a lot of it.

      1. If you add more discard to the starter you’ll have to feed it larger quantities, so I usually just keep a small amount of starter going while I’m trying to revive it. If you want to skip discarding that’s fine too. Or are you meaning you want to mix the current discard with your previous discard? If so, that’s fine as long as your discard is still healthy!

    3. @Ally, mix the current discard from this morning to the discard that I started with yesterday. I started a new starter yesterday *just in case* this one that I’m trying to revive doesn’t grow.

      1. Usually, the rule of thumb is not to use discard from a brand new starter for at least 2 weeks because it hasn’t been innoculated with yeast and bacteria to keep the mold and bad microbes down. I used the discard from my 24 hour starter right away cause it was made with commercial yeast. Hope that helps!

  13. I wish you’d give American measurements along with the metric. If I have to look up what 50 grams is every time i read a British or European recipe I’ll probably try a different recipe.

    1. Hi Louise,

      I understand your frustration, but the reason most sourdough recipes are in weighted measurements versus volume measurements is because of the ration required for sourdough starter. While you can convert it to volume measurements and have a “sort of close” replica of the original, weighted measurements are much better, and once you’re used to them, much easier to work with.

      The main reason is that volume measurements of dry goods are notoriously inconsistent. 50g of flour is always going to be 50g, no matter how packed or sifted it is. 1/4 cup can vary in weight wildly based on many factors. On the small scale, it can be overlooked, but when you’re getting into larger volumes of flour, it can absolutely affect the outcome of your recipe.

      It’s a little bit to get used to, but I prefer working with weighted measurements now – and I never would have thought I’d say that! I have a video up on YouTube about feeding sourdough starter and it may help convert you to the scale side!
