I have a sluggish homemade starter that seems to very slowly peak, have small bubbles, give off that "vinegar" smell and seems to overferment/overproof my dough into something stickier during shaping than when I finish my stretch and folds. This is EXACTLY the video I needed----had to comment before I even finished the video because the timing was SO APT. Thank you so much for all of your knowledge!!!! You ROCK.

Thanks Tom. You probably saved a lot of people from dumping out their starter and running to the store to buy yeast. Your video displays your knowledge of sourdough, how to fix your starter, and a entertaining delivery which made it easy to understand what an acidic starter is.

[@thesourdoughjourney]

Thank you. I appreciate the feedback.

[@yarnexpress]

Thanks, once again, for the science. I keep my starter refrigerated & TRY to refresh once a week. The day before I want to bake, I do 2 peak to peak feedings, refrigerate overnight, feed again & I'm ready to bake. Now I understand why this works for me. Looking forward to your upcoming refrigerator maintenance.

Loved the barnyard tragedy. LOL. Effective way of explaining what happens during the fermentation lifecycle. I followed your advice and did a 1010 feeding of my acidic starter and within seven hours I'm back up and running with a very bubbly and thick active starter. Great videos. Your sense of humor keeps it entertaining.

[@TheKlashvorn]

I've been using instant yeast for a while, always afraid to try nurturing a sourdough starter and I've finally taken the leap about a week and a half ago. I'm happy to report that I have a healthy starter after 10 days and I was able to catch the peak for my first mini baguette batch. With your example using cows and acid spitting dinosaurs, my mind is reminded to care for the cows. Save the cows everyone! Anyway, thank you for sharing your knowledge, findings and spending time laying things out for anyone interested in the topic 🙏 Happy sourdough baking!

I just want to say that this happens in microbakeries too. Yesterday, I had to throw kilos of dough in the compost because by the time the dough had hit the percentage rise I was looking for, it had completely liquified 🥲. I feed my starter two times a day, but I guess I haven’t being paying attention to what it was telling me and I paid the price for it 😄 Thank you so much for your videos! I’ve been baking sourdough since 2016 and I never felt I fully got it in a way that made sense until I found your videos.

I started uh, well, a starter, beginning of this year following an artisan SD book's instruction. After so many days the starter recipe dropped using whole grains. I dumped it and started following another book. That starter also struggled a bit but I think it was due to the whole timing issue of 24 hrs. in a day (starters don't wear watches). I switched to your advice and fed my starter just after peak. I listened/observed my starter for when she said, "Please sir, may I have some more?" This was a month old, weak starter and soon it changed to an overflowing mess on my counter regularly so I had to rethink my starter size vs. container vol. It's nice to not worry about the starter and just focus on the rest of the dough recipe. My loaves look great and I'm getting good compliments after doing the work. Thanks Tom.

[@thesourdoughjourney]

Thanks.

[@mnchaser]

Like a lot of things, I put fixing the real problem (acidity) off until last. Inconsistent starter rise times, sluggish levain, no strength in shaped dough, and no proof. Every word of this video is gold...it should have been the first thing I watched/learned. Thank you! I had previously been doing 1:1:1 feedings, but basically getting dough that wouldn't rise/proof. Super smooth, but zero strength (puddle). I'm convinced now it's acidity. I'm doing a few peak to peaks to get a feel for shortening times and then will be gradually switching to something like 1:5:5 - which I'm hoping is a great balance of strength ratio and convenience (~12hr peak). If I understand correctly... if I'm good with the time a 1:5:5 takes to peak/cycle, there's no quality difference between that and a 1:1:1 (or a 1: 50:50 for that matter). It's just quantity of starter (and waste) and the cycle duration.

[@thesourdoughjourney]

That is correct.

[@stephaniejones5715]

Really fantastic and informative video, thank you so much for the effort and time you put into it. I enjoy learning about the science behind what I'm doing, so I'm so glad I took the time to watch this. I was always confused by people's descriptions of starters being "sleepy" or needing to "wake them up", but I can see now that what it really comes down to is the acidity. I had many lightbulb moments here, including with your explanation of the effect of temperature on the protease. Living in Australia, where my kitchen has been averaging 29C in recent weeks, I have a new appreciation for why my sourdoughs seem to be breaking down so quickly. As a side note, it was interesting hearing you mention that keeping a starter in the fridge can make it hard to see when it has peaked. I keep a 100% hydration rye starter that very visibly doubles, peaks, and falls in the fridge. Perhaps an added advantage of a rye starter over normal bread flour. Thanks once again!

[@thesourdoughjourney]

Thank you. 🙏 Yes, rye starters behave a little differently.

[@barrychambers4047]

Great information Tom! Thank you! You Sir, indeed, should have been working at Nasa!😆 Just recently I'd come across the Detmolder two( and three) stage builds. The one on youtube (a professional baker presents it), the first build is with 5% starter and 70% hydration, with rye flour, at 75F for 12 to 16 hrs. The second build goes at 85% carryover starter, with 100% hydration, at 90F for 3-4 hrs. This is obviously too hot from what you've said? Also, Hamelman talks about the 3 phase Detmolder rye method in his excellent book, "Bread." I think, de-acidification, and building natural yeast is the goal of Detmolder methods.

[@thesourdoughjourney]

Thank you Barry. I will look into that method.

[@shaebellow6826]

Great video, Tom! Can you comment on what is happening when people post that they made a gorgeous fluffy high standing loaf of sourdough from starving starter? Like starter that's been in the fridge for 4 weeks without being fed and then they just take it out and use it in their bread recipe without feeding it? Your explanation of what happens at each stage of the starters process is always so logical. The yeast is most active at peak, and it makes sense that this would be the time you would want to use your starter in a recipe. But these people who use starving starter (And I've done it effectively myself when I've been desperate to make a loaf and forgot to create the levain) really blow my mind! I mean, it makes sense because when you mix your dough, you are effectively giving the starter a giant feeding with all the flower you use, right? It does take longer but it's still rises the dough pretty well. Sometimes exactly the same effectiveness as starter that is used when it's at its peak. So I really would love to understand what the argument is to create the levain in the first place. Is the idea that eventually that starter will become too acidic or are there other reasons?

[@thesourdoughjourney]

You can use an unfed starter, but that doesn’t mean you should. The results are very inconsistent depending how long it has been since it was last fed, and some other factors. It’s hard to say without knowing the specifics of each case, but a few things I’ve seen with my tests: You can use a refrigerated starter for about one week after its last feeding, with pretty good results. The results go downhill after that. An unfed starter works best in dough at lower percentages (10% starter versus 20%, for example), and it works best at low dough temps (70F versus 80%)l. Lastly, it works better at lower hydration (70%) versus high (80%). If I used 20%, 2-week unfed starter in 80F dough with 78% hydration it would be a disaster. If I use 10% in 68F dough at 70% hydration, it will make a decent loaf.

[@lindahammond249]

Tom, you are a rock star!!! I finally understand what was happening to my starters (yes, PLURAL)! I couldn't get them to rise consistently, and I tossed them all.

On topic, I was afraid of leaving my starter in the fridge unattended for an upcoming trip and decided to put it in the fridge as a test run. I put it in right after feeding it. Three days later I took it out and placed it on my counter and it doubled by the morning of the next day. It is more lively than before I put it in. Before, I had to keep it in a yogurt maker to keep it around 75° F. Now it's doubling daily at 65°F-68°F. I believe it has strengthened because of letting it rest in the fridge.

[@thesourdoughjourney]

Yes, some starters come out of the fridge very strong.

[@thesourdoughjourney]

Thank you. 🙏

[@torben2333]

Thanks for the helpful video! You put so much effort in it. Thanks for that! I have two questions, because I find it a bit confusing when I heard it. 1. You talked about the peak-to-peak method and mentioned, that you take out the acidic starter from the fridge and feed it in a 1:2:2 ratio. But in the high feeding ratio section you mentioned that this ratio is not so good for acidic starters, because you take all the acidity with you to the next starter. How does that fit? 2. We talk about peak times of 4 hours, but besides temperature this is highly dependent on the ratio, isn't it? So when you use a 1:2:2 ratio it would develop much faster in comparison to a 1:10:10 ratio, does it?

[@thesourdoughjourney]

I knew that part could be confusing, but I think you have it backwards. High feeding ratios carry over very little existing starter, so they sometimes can knock down the acidity in one or two feedings. That's why I recommend it first. If that doesn't work, then I recommend the peak to peak method, but if you do the peak to peak method with high feeding ratios, it strettch out the time to much and it's difficult to monitor the starter to catch it at peak. So I am recommending a "suboptimal" lower feeding ratio (1:2:2), so you can get more feedings in during the day or in a short period of time. It is purely a scheduling convenience. If you had a lab team monitoring and feeding your starter 24/7 , then you would do peak to peak with 1:5:5. But if you need to work, sleep, etc, you can get more 1:2:2 feedings in and it has the same outcome in the end.

[@jmj9063]

Ive been doing small experiments since starting my sourdough journey. Even got my kiddos in on them. Its been fun but sometimes i just want to know why right now. You have just made my day and im loving the videos.

[@thesourdoughjourney]

[@crystalsypniewski857]

Great information again. And perfect timing. I will use this information immediately. Do you have any suggestions for accomplishing the same thing but on a 12-hour feeding schedule as opposed to 4? I'm doing a 1:5:5 feeding schedule because it's what I can manage with my work schedule, but will that help reduce the acidity?

[@yousefalabdrabalnabi6356]

Tom, thank you for the invaluable insights you share on sourdough baking. Your videos have been incredibly educational for me. I have a few questions: 1. Regarding sourdough starter, could we increase the percentage of starter in the recipe by using all the water for the feeding (1:1:1), then adding the remaining flour to adjust the final hydration of the dough? Basically using higher sourdough stater, like more than 50%. 2. I've been making Neapolitan-style pizza with sourdough, and achieving a strong gluten network is crucial for stretching the dough without tearing. Considering the acidity of sourdough can weaken gluten, would you suggest adding a small amount of baking powder to counterbalance this effect? Sometimes, during a 48-hour cold fermentation, I encounter issues (thanks to your insights I know why now 😀) with flat, weak, and tearing pizza dough. Would baking powder help in such cases? 3. In your video "The SECRET of Bulk Fermentation: Measuring Dough Temperature and % Rise - The Two-Factor Method," when would you recommend shaping the pizza balls? Should we complete bulk fermentation to 100% and then shape the balls for final proofing? Or is it better to shape them before bulk fermentation and treat each individual ball separately during bulk fermentation?

[@thesourdoughjourney]

Thank you! 1. When you exceed about 35% starter on your dough, the acidity and weak gluten from the fermented starter begins to break down the dough structure too quickly. 2. I’ve not tried adding baking powder to reduce the acidity. I’ve not heard of any sourdough bakers trying it. The science seems to indicate it would help, but I’m skeptical only because I’ve never heard of anyone doing it. 3. I would shape the balls after bulk fermentation.

[@creativereindeer]

So helpful! I was close to pitching my starter that I got off a friend and left in my fridge for a month.

I must have the most acidic starter on the planet. A book I used describes to keep your starter before using it in a dough on 30 degrees Celsius for a couple of hours to “boost” it. Now that I’ve watched this video I understand how horribly messed up my starter is

[@thesourdoughjourney]

30C is very warm.

[@zeshef]

How do you manage acidity while also boosting up the aroma and sour notes in the finished loaf?

[@thesourdoughjourney]

The sour flavor develops as the dough ferments. It is not as directly related to the acidity in the starter as many think. A "sour, acidic" starter doesn't necessarily make a "sour" loaf. I've used all kinds of starters over the years, and the sourness generally comes from a long cold retard for final proofing.

[@zeshef]

@@thesourdoughjourney got it. So: low acid starter is a must, because it guarantees better chances of higher yeast. But cold final proof for longer periods will develop a stronger "sour" aroma/flavor.

[@kiraamber8767]

Your videos are very informative, thank you! Is there a difference if your starter is new? I started mine from scratch about 8 weeks ago and I never see this type of information differentiated for early stages of starters.

[@thesourdoughjourney]

This issue is more common with mature starters.

[@jbirdyhome-4050]

This is sooooo helpful!!! I knew my starter was too acidic and my new 1-5-5- was at peak in 6 hours, but I plan to continue strengthening it and checking the ph until I get it to a reasonable 4ish level. It started at like 3.91 and that was way acidic. Very helpful!!! Thank you I like the explanations, the demonstrations and the long videos. I feel sorry for the cows, though!

[@thesourdoughjourney]

Thanks. 🙏

[@StagArmslower]

I was an ignorant about the starter and after two screwups I do it methodically and do my bulk fermentation in my proof box. At 10pm I prep the levain 1: 5 :5 so in the morning I can bake. From the levain jar I prep another levain 1:5:5 and when it raises a little bit I put it in the fridge for the next cycle. If I use 1:1: 1 feeding my levain become acidic and flat in few hours. As usual great presentation.

[@thesourdoughjourney]

Thank you? 1:5:5 is a good ratio to keep the acidity down all the time.

[@kathyisern4890]

Tom, you are a gem! Thanks for ALL of the information you have given us - and the sense of humor you impart while doing so! I have a question and I apologize if I should be able to answer it after this video but haven’t connected the dots to do so. So I’ve fixed my starter with one of the two methods you showed here. It is now in the rising stage of the third peak-to-peak feed. However, I will need to put this new and much improved starter in the refrigerator because something has come up and I cannot start making the dough right after it peaks. I can start the dough process the next day, so I want to refrigerate it so it won’t starve in the meantime. When is the best time in the cycle to put it in the refrigerator? Right after peak?

[@thesourdoughjourney]

Yes, you can always refrigerate it. Usually before peak is best (after it has begin rising), but you can also refrigerate it at peak and use it directly from the fridge for about 3 days.

[@Spinning4Lisa]

Thanks Tom! I needed this so much! Acidity issues are exactly what I thought was sabotaging me, but I wasn't sure how to remedy!! What do you think about letting whats left of my starter after use, dry out in the jar? Then reconstitute it a day or two before I need it again??? Thanks for all your hard work!!

[@thesourdoughjourney]

Some people do that. Look up the “scrapings method” on Bake with Jack channel on KZbin.

[@bethmarquez865]

This is exactly the info I needed to understand the whole process and why my bread fails.

[@thesourdoughjourney]

Thank you! 🙏

[@yiayiavirgeniusfavoriterec6726]

Very helpful and informative, as always! Quick question…do you have a preferred ratio of bread flour to rye or wheat flour in your starter. Should it be 70/30 bread flour/rye or wheat flour?

[@thesourdoughjourney]

Thanks. I use 50/50 but I think many different ratios work.

[@yiayiavirgeniusfavoriterec6726]

Thanks so much!

[@yairdvora871]

Wow Tom! I loved it! I bake once a week. I feed my starter right after using it in the dough at 20:30:30 and put it in the fridge. The day before making the next dough I take it out in the afternoon, at around 10pm I feed it 20 (or 30):160:160 and in the morning it’s ready to be used in a dough. I never paid attention to the acidity in the starter. I will from now and do maintenance (as much as I can) thank you again for these videos!

[@thesourdoughjourney]

Thank you. Your method is similar to mine. It is probably working fine; but may benefit from a discard and feeding before making the leaven at night. But if it’s working, don’t change anything!

[@yairdvora871]

@@thesourdoughjourney I’m going to make dough tomorrow. I took my dough out now and will do one peak feeding before the final feeding (at peak) overnight.

[@Simple_and_natural]

This video is A M A Z I N G! I understand now why my breads are gummy do not brown do not rise do not keep their shape. I still have a doubt, how to determine the peak point if I do not have a ph reader. You said for instance that your first attempt took 13 hours to peak, that is a long time, i could think that it peak at 11 hours or 14. The volume duplicates? Triplicates?

[@thesourdoughjourney]

Thanks. My starter usually doubles. Some triple.

[@dorcashobbs4668]

Anyway to guestamate how long a starter is at peak? Or is there too many variables? Temperature, flour type, etc. Love your examples! You would have been a very interesting science teacher! Keep the videos coming!

[@thesourdoughjourney]

It’s impossible to know how long it will stay at peak. It depends on the flour, the hydration, the temperature and the acidity. Maybe more.

[@JS-ne5pk]

Excellent vedio, bu I heard that putting starter in the fridge makes it lose many of the good anzyme or bacteria, and there for its better to dry it out. Can you do some research about that and tell us about your findings

[@thesourdoughjourney]

Not true.

[@user-wi5sn6rb8w]

Thank you thank you! I’ve been looking for something like this forever. Would you mind clarifying what peak looks like for an acidic starter? As in, should I prioritise height or bubbles? My starter stalemates at a certain height but the bubbles at the top comes much later.

[@thesourdoughjourney]

Usually it will peak at a lower height and will fall quickly after peak. The bubbles are difficult to use as an indicator.

[@user-wi5sn6rb8w]

Thank you!

[@Cindy-ln3do]

Hi Tom!!! My 30 day old starter is still taking 8-9 hours to peak at 75-77 degrees, feeding at 1:2:2 every 24hrs (increased to 1:3:3 yesterday). Smells of vodka/acetone by feeding time with lots of pinpoint bubbles. I planned to stay that course until this video - would you recommend one of these methods for my situation? Or is mine perhaps too young for an intervention? I love love your content - I’ve been “studying” on your channel this last month while waiting for my starter to become bake-worthy and can’t wait to put all of this information into practice!!

[@thesourdoughjourney]

Try a few feedings of 1:2:2 at 12 hours (assuming it is clearly past peak in 12 hours).

[@stansieniawski]

Classic 👌

[@thesourdoughjourney]

Thank you!

[@SandiHooper]

Super thorough. How can there be any questions on this subject left? Well, I have a math question: the reason to use 1:1:1 is to facilitate calculation of hydration levels of your loaf, right? So how does a 1:5:5 ( for example) change the hydration calculation? Thank you so much for the incredible work on this, and all of your videos.

[@thesourdoughjourney]

As long as the last 2 numbers on the ratio are the same, the starter hydration is always 100% (equal parts flour and water). 100g of starter at 1:2:2 and 100g of starter at 1:5:5 have the same hydration % and would impact the dough hydration exactly the same. The dough hydration is only imp@ ted by the starter hydration if you change the totally quantity of starter used in a recipe, such as 200g versus 100g. To calculate the “recipe hydration” you need to add the flour and water components of the starter to the dry flour and water in the recipe.

[@jacquigriffin5973]

Thanks so much for all the research leading to greater understanding, but... so much discard that I can't throw out. I came here to bake good bread but now I spend too much time making and eating pancakes, muffins... I just wanted to leave the starter in the fridge to use when I make bread and then feed and forget till next time... on repeat. Help!

Thank you.

Hi Tom! I’ve watched most of your videos over the past month or so and there’s one issue with my bakes that I can’t seem to shake out. I’m having trouble baking out all of the moisture in my loaves. I’m still learning and my starter is still young, just over a month at the time of making this video. It doubles predictably within 6 hours but never 4 at 78°f. I’ve watched your video on bake temps, bulk fermentation, stretch and folds nearly to completion. I’m methodical about ingredients and measurements in grams so all of that is on point. Over time I’ve become more successful however the remaining issue is the oven spring and gummy/moist dough. Is a gummy dough a product of a weak/young starter or baking time and temperature? I’ve tried high and low temps specified in your baking temperature video and my best result was on the lower and longer end. I’ve had varied levels of success (mostly moving in the right direction) of cutting off BF. Any info you could share or link me too would be greatly appreciated.

[@thesourdoughjourney]

"Gummy crumb" is one of the most common problems and the hardest to fix. First, you want to make sure your dough is fully fermented. Really try pushing the dough right to the edge of overproofing. That's when the crumb becomes the most delicate and releases more moisture in baking. Second, try different baking methods. More time and temperature in the oven evaporates more moisture. Some people "cure" their loaves. After the loaf is baked, put it back on the oven on the rack, with the oven off. As the oven cools down, it should not brown the crust anymore, but it will evaporate another 25g of water out of the loaf, typically.

[@gingerhns]

@@thesourdoughjourney thanks for replying, I’ll keep going until I get it right!

[@krissand12]

Thanks for all the great information! Question- while in the process of feeding and strengthening starter I overnight it in the fridge to slow the peak and not have to wake up to check. So in the morning when the starter is removed from the refrigerator how can I tell if it’s peaked while in the fridge or if it needs to warm up to see if it continues to peak? I find when it’s cold I can’t really tell what stage it’s in and if I need to feed it right away or allow it to warm to 75degrees or so. Thanks in advance.

[@thesourdoughjourney]

Yes. If you put it in the fridge, I always give it time to come up to room temp to see what’s going on.

[@jonathanpoirier2164]

Excellent work as always. I started sourdough baking about 3 months ago. I keep my starter on the countertop and TRY to feed her (she's called Vitalyne) every 24h or more. I noticed a vinegar smell that stays in my starter even right after the feeding. I went to give Vitalyne a 1-5-5 feeding while watching your video and I hope i'll see the difference in my next loaves. Thank you so much for this video and can't wait for the next one on keeping the starter in the fridge. I have a question thought, do you create your levain the night before baking with a 1-5-5 ratio for your starter to reach peak only the next morning and not during the night ?

[@thesourdoughjourney]

Thanks. I usually create a leaven at 10pm with a 1:10:10 feeding and it will peak by morning.

[@tuyetngocnguyen1684]

This video really answers for what happened to my starter . All the signs in the video happened to my starter, smell like vinegar, make the dough after colf proof like a pancake and BF took me 12 hours with 76 degrees 😢But please help im trying the high feeding ratio 1:5:5 for 4 times already but my starter even tho it rise but the bubbles on the sides of the jar super tiny like y can barely see and take like more than 12 hours to peak what should i do w my starter now 😢maybe i discArd too early? I tried the peak to peak method after i took my starter out of the fridge with 1:2:2 ratio twice a day for 2-3 days before i baked but my starter still seems really acidic

[@thesourdoughjourney]

Try a very high feeding ratio a few times.
