Stop Over Proofing Your Sourdough, Use This Experiment to Find Your Optimum Proof

[@michaelosborne3414]

I've watched quite a few of these types of experiments on various channels, with people pushing the limits of variables like proving time, "over" kneading, sourdough starter timing etc. It seems that often the result shows that, while there is an optimal preference for each variable, the extremes either side are actually usually quite forgiving. This is reassuring for amateur bakers like myself

[@CulinaryExploration]

I'm really pleased that the schedule is working out for you. It's pretty solid!

[@kevinu.k.7042]

What an excellent video - You bake well sir! The ear is all about the angle of scoring. French bakers are taught to score with their first finger knuckle pointing upwards to present the blade at an angle to the dough. I don't like ears, they make for sharp crust edges in the mouth. So I hold the blade vertically to the dough. TBH This ear thing is North American fashion. Born of Chad Robertsons signature Tartine style. If you watch French artisan baking videos they seldom score ant an angle to make an ear. If I might add though the fermentation is arrested in the fridge the protease enzymes continue to work, albeit slower. These enzymes 'cut up' the gluten structure and it is this weakened gluten structure which gives the large irregular vacuoles in the finished bread. Having said that the enhanced flavour in naturally leavened bread is caused by the organic acids , mainly reduced by the LAB bacteria, reacting with the alcohol made by the yeast. These reactions are much slower than the yeast fermentation which is why slow fermentation and, or retarding in the fridge gives the finished bread that much more flavour. In both cases we slow the yeast and LABs to enable the organic acids etc time to keep up. Superb video, great baking and thanks for the fridge temperatures and times. Excellent!

[@tonycasarrubia1394]

What I have been doing is bulk fermentation between fifty and seventy five percent in my oven with the oven turned off. It usually takes between two or three hours to reach that desired fermentation. I then form my individual loaves and place the baskets in the oven for one hour additional bulk time before placing them in the refrigerator for a twelve hour cold fermentation period. Although this process is not as controlled as your process it has been very consistent and produces a light lacy crumb similar to your preferred loaf from the video. I have experimented with higher proofing temperatures during the bulk periods and I have concluded that the room temperature bulk has given me my best results.

[@mrgreenbudz37]

What are your temps in the oven and are you leaving the light on? I ask because my oven with the light on for 2hr can hit 81F and with the light off stay around 68F

Kudos on you for stating the temperature of the fridge. No one does this. And it's bloody important~!!

[@lavague7648]

Many thanks for sharing your journey. What i tested with spelt sourdough was 10% increase and 3 hrs bench proofing (75 to 100% rise) before cold proofing. I manage this way to get for first time few pockets in spelt bread. Open crumb for spelt bread seems to be very challenging.

[@juukame]

this is the exact kind of sourdough video I've been hoping for ever since I started sourdough. so many other recipes call for less bulk fermentation, or more or less fridge time and there was never any consistency and it was really frustrating to know what method would give better results. This video shows very well how the different variables affect the result

[@CulinaryExploration]

Pleased it was useful. There are so many possible combinations, more or less volume during the bulk fermentation, longer or shorter proofing in the basket. I think it's worth testing some combinations out yourself, pushing the boundaries a little and seeing what happens. Cheers for taking the time to comment :)

in germany these big holes in bread are considered a flaw. as whatever you want to put on there is trapped in the holes. consider fresh cheese, honey or any type of jam, it just runs through. also if you want to overbake it with cheese, like french croque monsieur, the cheese runs through. so air pockets should be around 2mm in size, not more. the rest has no practical use

[@heksogen4788]

2mm? that would be very tight crumb, i think 3-4mm is still perfectly fine.

@@crystinamcdonough9120 yes but what is the purpose of bread with big holes? to eat it single? cause neither butter can be spread properly. nor any other soft thing. also it takes more space, uselessly. and falls apart while cutting. ? it just makes no sense logically

[@tonycasarrubia1394]

Big holes are about maintaining a very light crumb and for those that like this texture we don’t care about the butter and jam following through the holes. And for those that want EVO with their bread it’s heaven.

Your crusts turn out so beautiful! (I like being able to enjoy the entire loaf of bread, including the bottom.)

[@CulinaryExploration]

I find baking on a good stone gives great results, especially for the bottom of the loaf. When I use my challenger pan I reduce the temperature to 210 and am careful not to pre-heat it for too long, that gives great results too

[@magnustorque5528]

Very interesting because I was recently struggling with producing really great looking loaves (externally), but inside I would have some random bits of very dense areas usually about 3/4 from the top and often in the center of the loaf where the volume is the greatest in terms of height. I had been bulk fermenting to a state of very "jiggly" with lots of little fermentation bubbles. It's what many said was where it had to be . I was doing four sets of stretch and folds and I know the structure was there and my starter is very active, etc. It was very frustrating. I use Robin Hood all purpose unbleached, and I'm at about 72% hydration overall when you include the starter hydration. I decided to back off on the bulk fermentation time. I waited until the dough had some jiggle, but not a lot (about 4.5 + hours at 80 degrees F). Then I pre shaped it and let it rest for about 15 min. After that I shaped it and let it final proof on the counter for about 55 minutes (usually I would only be able to let it final proof for about 20 min. before the finger test failed and no spring back would occur). Voila..the best bread I have made thus far. It sounds counterintuitve, but it worked for me. The crumb is actually much more dry which is great since it isn't as chewy when toasted like it was previously. The crumb is also fairly consistent regionally. Not really open, but not super tight either. I think that is more about shaping and the amount of tension I apply when shaping. I can play with that. The main thing is that those little gummy bits are gone. I'm super happy about that. Now I can start final proofing it in the fridge again to find out how long I will need using that component since it does add a lot of flavor to the end result.

I bought some straight sided canning jars that are ONLY for sourdough, and I also bought some sanitizer to clean jars and utensils to prevent future contamination.

I am pretty sure that Bob's Red Mill Artisan Flour is better than King Arthur based on my experience and it doesn't seem to be as difficult to obtain now.

Great video! I do a lot of experiments. I live in the tropics so its around 27c room temperature. To stop it over fermenting overnight in the fridge I now put it in the freezer for half an hour once it's put in the banneton and then in the fridge overnight. This brings the temperature right down and it doesn't overproof in the fridge.

[@helenjohnson7583]

That’s very sharp thinking! Good use of temp control!

Have you tried using a cool box with ice blocks to lower the temperature and extend the fermentation? Ive had good success with that :)

@@CulinaryExploration yes I have but it's hard to maintain a stable temperature that way, particularly in the summer lol. I find it ok to ferment at 27c to 30c but it was taking too long for the dough temp to come down in the fridge overnight when proofing so the freezer trick has really helped.

[@viralamin5568]

My theory of why test 4 turned out the way it did: you allowed it to proof longer in its final form/shape. I think that gave you the regular crumb structure. The other tests were properly fermented but didn't have enough time or opportunity to expand in their final form.

[@vincentlabruzzo5368]

3 was proofed the same way but bulked till doubled 4 was bulked to 75%

[@viralamin5568]

@@vincentlabruzzo5368 That's a good point. I guess #3 was overproofed in comparison with #4. I wonder then whether #4 turned out the way it did because it was given longer than #1 and #2 in the basket (final form) and still had more active yeast, i.e. not overproofed.

For the recipe I've created I can have almost a 100% increase in volume but if I don't have any doming near the top it can still be underfermented. I've found that different recipes can have really different fermentation requirements. There are just enough variables to keep us all experimenting.

[@mrgreenbudz37]

As always, a great video, Phil. To clarify, you bulk fermented at 77F until you hit a 75% increase, shape, then did a 2-hr proof in the banneton, still at 77F, and then into the fridge for the cold ferment at 37F overnight?

I love this!! Philip could the uneven crumb come a bit from your shaping technique which I have adopted. You handle your doughs much more gently than others do and as seen on many KZbin vids. I know because it took me a long time to change.

Phil, wouldn't giving the 75% dough another 2 hrs put it to 100%? would be helpful if you had marked them 50%, 75%, 100% and so on instead of time. Always a joy to follow your technics and experiments.

[@CulinaryExploration]

Not sure Mike. The bulk is easy to measure by volume. Measuring the increase in volume in the basket is a bit more tricky so I opted for time. I found that 2 hours in the basket was perfect, but cutting the bulk from 100% to 75% made the difference in the crumb.

[@DirtRiderLife]

I've been playing around with various soughdough recipes for a year or so and after 60 loaves have settled on a different , maybe unique method but I doubt it LOL. One of the things I do is use a hand held blender to completely dissolve the starter into the water before adding flour, my logic is to obtain a more even distribution of starter yeast throughout the dough, that and the thought of a blob of starter in the middle of my loaf doesn't sound good 😃

[@helenjohnson7583]

That makes sense to me! Baked goods often turn out a more consistent quality with thorough mixing in carefully planned steps. Please let us know anything else you have discovered!

[@DirtRiderLife]

@@helenjohnson7583 My method is similar to @Culinary Exploration, I feed my starter the night before so its peaking around 7am, I warm my mixing bowl and the water, to around 95F, for my dough, add salt and dissolve then add starter and blend to a soup, add flour and mix, rest 30min then fold, rest another 30 min then fold, I then bulk rise the dough in my oven with just the light on for 4hrs, not sure what temp the dough is but the bowl is just warm to hold, I'll check the temp next time. Fold and shape the loaf, place in a basket covered with film ( I use a , new LOL, disposable shower cap) for 4 to 7hrs at room temperature (my kitchen can be between 20-25C) . Bake in a fan oven @ 425F on parchment in a preheated (45min) dutch oven for 25min followed by 15min @ 375F dutch oven lid off. My loaves burn if I don't turn down the temp, I'm @ 3500ft and an arid climate but I've found this method produces very consistent results for me. My dough probably only rises about 50% each time on bulk rise and in basket, not that much really and my starter rarely rises more than twice its size, nothing like most of the KZbin videos. If I could get a little better baking rise I'd be delighted, any ideas?

Hi Phil, nice work. I’m also curious to know whether you can repeat the results of this 75% bulk expansion and 2h proofing. I like the fact you remain open minded about your results. I can’t tell you how many videos I’ve watched where home bakers do these types of experiments and then tell you with certainty what knobs do what in the end. They don’t realize that perhaps their shaping inconsistencies or scoring skills caused most of the differences in the final loaf. Or that they weren’t careful in keeping same conditions for all experiments. There is one sure way to know whether you have allowed for a proper bulk fermentation- use a high quality pH meter. Once you’ve determined the proper bulk time (pH between 3.9-3.7), which BTW, takes into account all parameters such as temperature, starter inoculation, flour, hydration, etc., you can then play with the proofing time, keeping your temperature constant as you’re doing. Check this video out, if you haven’t already seen it. kzbin.info/www/bejne/n6W9foydnZqNeZI He has another video as well where he talks about the use of a pH-meter. Enjoy!

I had issues after moving recently. The common wisdom is 20/20 for covered/uncovered baking. Well, after the first 20, your bread should already be 92-95C. In my current oven that takes 30 minutes. I just used a little digital thermometer, poked the middle, and figured it out that way. Worked really well, but took a few bakes to nail down.

@@mattymattffs hmm, i guess it also depends on how big or small the loaf is as well. I suspect the internal temperature may not hit it yet so I've purchased a instant read thermometer and shall wait for it to arrive before checking it like you do half way through!

How do you judge the percentage increase in volume? It’s difficult for me to guess exactly how much the dough has increased in volume by just looking at it in the bowl.

@@CulinaryExploration It goes from 21c to 90c with 60-80% humidity and it folds flat into a laptop shape when you’re not using it. I love it!! I haven’t used it with sourdough yet though I thought a long slow proofing would develop better flavour. Maybe I should rethink that. On yeasted doughs I have found it a godsend. The dough rises consistently and doesn’t require covering because it’s in a humid environment already. I would highly recommend it to anyone that was an avid baker. Thanks so much for all your content. I really love your videos!

Hello! How can you tell if it's 50% or 75% proofed? What does that mean exactly?

[@sarasandal7170]

Wouldn't proofing it for two hours be the same as bulk fermenting it for an extra two hours, shaping, and putting it in the fridge? Does it make a difference?

[@study92song68]

Great video! My oval shaped dough always came out to round. Do you think it's because of overproofed?

[@CulinaryExploration]

Could be. Why don't you do a couple of experiments, changing the proofs time and comparing the results?

[@lindadurand247]

What I would like to know, does any of these experiments produce the tang that sourdough should have, I have yet to find anyones recipes or methods that end up with those results

[@CulinaryExploration]

Thank you!

[@chrisdeangelis4616]

Man, I really think I have been overproofing my loaves. I was getting some really beautiful loaves then suddenly they all got flat with no ear... wonder if because getting warmer here? Even did the sample dough method. Maybe my shaping technique changed (last couple were very difficult to handle - been at 76% hydration so maybe drop back a tad...) 🤷🏻‍♂️

[@CulinaryExploration]

If the temperature has increased it will push the fermentation along quicker. Keep a close eye on the bulk fermentation and proofing stages and dial them back if needed. Decreasing the hydration may help, especially if the increased temperature has made the dough trickier to handle or has caused the dough to spread a touch more when you turn it out of the basket.

[@hiitstam]

Thanks for this! New to the journey so this helps. Would you say the 75% + 2hr cold is closer to 100% rise once taken out of fridge (when cold ferment is finished)?

[@noppornwitoonchart]

From the last experiment at 75% and 2 hrs in the basket, had the dough risen to 100% before retarding in the fridge?

[@RovingPunster]

You proof/ferment at 77F ? Seems a tad low to me, but im still learning. 🤔 Ive read that the various strains of bacteria and wild yeasts that comprise a typical sourdough culture scatter in their optimum temp preferences in the mid to upper 80's thru the low 90's (F), and slightly higher for things like thermophilic yogurt (95-104F). Yeast has a broader thermal range (ale & wine yeasts like 70's & 80's, lager likes 40's & low 50's), but the strains most suited for baking like pretty much the same range, or a smidge warmer. For that reason ive been fermenting my sourdough in the vicinity of 89F internal as a thermal compromise. For example, if I park a 1 kg boule in a 2L cambro, spray lightly with oil, seal it, then drape with a tea towel as a light thermal buffer, i cen proof in my digital food dehydrator set for 95F ... it maintains a rock steady 88 - 89F internal temp in my dough. If I wanna slow it down, ill move it to my fridge at 35F, where activity speed drops about 5 fold (i e. 3hrs at room temp is in the neighborhood of 3x5=15 hrs in fridge). Anyway, im just sharing my method ... id enjoy hearing temp targets and maintenance methods by other bread aficianados.

[@lauriegertenbach3421]

I have a quick question...I was told never to use stainless steel with sourdough, only glass, plastic or wood. Is this true as I see you using stainless steel?

[@antonio-romano]

Hi Phil, thank you for the very nice video’s! Did you notice any differences between the use of rice flour or semolina to seal the dough? I always use semolina so I'm curious to know the reason of your choice!

[@CulinaryExploration]

I always used my bread flour, but one day I tried rice flour out of curiosity. The dough isn't inclined to stick at all so I've stayed with it. Now I'm milling at home I may switch and start experimenting with the bran I sift out of the milled flour.

[@wickwire6500]

why when I take the bread out of the fridge it does not stay firm in the oil paste and when I carve it it deflates?

[@lawrencekellie]

Is the bulk fermentation information in this and the previous video valid for non-sourdough bread? Is it directly transferable to non-sourdough bread?

[@ThePhilbox]

Great exploration, truly. Bit of a shame you didnt keep using the dough in the jar to assess how far things had gone during basket proofing and refrigeration. For the first part of the experiment we have real data, then anecdote for the second. If you ever do this type of experiment again i'd be very interested to know what happening with the volume and texture of the dough in the jar all the way through up to the point it goes into the oven.

[@johnrose1258]

Hi Phil, great videos. Here in Malaysia the kitchen temperature is between 32c and 34C and humid.Its hard to determine the correct bulk fermentation time at that temperature. I know a lot of people in SE Asia who have trouble making sourdough because of the temperature and humidity. Since you have you temperature controlled cabinet it would be good if you could investigate making sourdough at these temperatures. I know if would be appreciated by a lot of people. Otherwise if you don't get time, can you document how to set up a temperature controlled cabinet like yours, one that drops the temperature to 25C. Thanks

[@CulinaryExploration]

Hi John, I've uploaded a video on the YT channel and have a blog on the website about the fermentation chamber. You could try using a cool bag with an ice brick to create a cooler area to bulk ferment. I'd suggest trying to create a cooler fermentation area rather than trying to make sourdough in 34c temps. I'll have a video coming soon on baking in higher temps. Hope this helps

[@boonjabby]

Agree with Phil. Sometimes my house has high temperatures here is Australia. I use a cool box (esky, drinks cooler) and regulate using ice cubes in a plastic bag. Works better than sweating out my dough on the 30° counter top

[@zhouly]

I live in Singapore which is just south of Malaysia and just as hot and humid. I too have had success using a large cool box with an ice pack to maintain a temperature of about 20 degC for bulk fermentation and initial proofing. Works well enough, except that there will be some water condensation on the dough due to the high humidity here.

[@jasonswain7083]

Hi I'm in Philippines same problems but I now chill all the ingredients I keep 2 kilos of flour permanently in the refrigerator then put the nearly ice water mix in a spiral for 5 mins cover the bowl for 20 mins or so then add starter and salt mixing for 6 to 8 mins on high this gets the dough to the right temperature about 25c then straight into refrigerator for bulk fermentation folding every 1 hour 4x then shape put in bannetons or cush straight in the refrigerator and bake at 7am the trick is don't start until the heat of the day has gotten cooler like around 6pm 7pm good luck and this guys channel is great oh and try 60 % and one at 65% or higher hydration and you'll be amazed cheers

[@qtie88]

What does it mean increase the bulk fermentation? Does that mean let the dough ferment longer than what it needs to and by looking at how many overs so it's not over fermented? Like when you say by 75% bulk fermentation and 2 hours poofing

There are many combinations Bryony and it's tricky for me to know what's going on with the crumb without seeing the process. I'd suggest experimenting with different bulk fermentation and proofing combinations to see what works well for you.

I use 100% Einkorn flour for health reasons, but this was what I was going to try next myself (won't get as much of a rise due to the nature of Einkorn). My recipe calls for 3 turns but the dough gets really tight, I've suspected 2 turns with a bit more time in between might be the thing. I've already been doing 75% on bulk ferment and longer second proof, I feel it gives better results.

[@CulinaryExploration]

I find 2 turns is more than enough for this dough, it works well with a no-knead approach too. How long are you leaving it in the basket for?

[@xiaowees]

is it a must to fridge the dough overnight or can i bake it straight away once its done proofing in the banneton?

You can bake it straight away. I like the overnight ferment as it improves the flavour and makes the dough easier to turn and score before baking.

Ok, help me out here, because I'm getting lost. What is "bulk fermentation" in your way of doing sourdough? Many people teach that you knead the dough, put it in it's final shaping basket and "bulk ferment" it in the fridge overnight, mean the bulk of the fermentation and "proofing" is done in the fridge overnight. I have only had one time that that method worked. I'm thinking your method is much like how you work with regular yeasted dough, with a first rise, shaping, second rise... then your putting it in fridge overnight for the fermenting part? Am I understanding it right?

[@CulinaryExploration]

Hi Jen, I have only used this method to make sourdough. The dough is mixed and sits covered for bulk fermentation period, in which time the dough is often stretched in some form. After the bulk fermentation the dough is shaped and placed in a basket for the final proof, and then baked. I hope this helps :)

[@mauryanderika]

Question: for the 75% bulk/2 hour proof, what did you base the 2 hours on? Did you monitor your “control” dough to see when it had doubled, then called proofing done? Or did you just go by feel/poke test? Thanks for the videos!!!

[@CulinaryExploration]

I've been asked that a few times Maury. I did think about using the control dough to continue monitoring the dough during proofing, but couldn't really see the point as the main dough is knocked about when shaping. So once it's in the basket I need to use touch to gauge when the dough is inflated properly, that won't be connected to what the control dough is doing. What are your thoughts?

[@mauryanderika]

@@CulinaryExploration Ahh that’s true. At that point, bulk fermentation is still continuing - but all the control would do is show expansion of the control. I’m always looking for a crutch, haha, but need to hone my skills in feeling and “poke testing” for proofing being done.

[@carolmelancon]

Cambro makes translucent (polypropylene) and clear (polycarbonate) , food-safe containers with printed volume measurements and lids in various sizes that are not expensive. If you bulk ferment your dough in it, you can see the height of your dough to easily track the increase. I put a small piece of masking tape on the outside of the container to mark the starting point of the dough.
