Wonderfull video. Very educative. I have used stiff starter in order to have more controlable fermentation acc. to your videos. A couple of weeks ago i ve started having inconsistent results and in one case i had complete degradation of the dough. We have 35 degrees in Athens this period and i assumed that this was due to elevated temperatures boosting lactic acid formation. Searching further, i have realised that feeding just before baking is one very efficient way to reduce acidity. Although at cooler periods i have using stiff starter, 1 week old, directly from fridge without any problem at all, that was not the case in summer period where fermentation temperatures rise kicking a boost in lactic acid formation. What would be intresting is to explore alternatives to control acidity by using buffers like baking soda. Sourdough is definately a challenging journey 😂 what makes it so wonderfull. Happy baking

Sourdough literally ferments itself whether you stress or not

[@edwardlevitan5416]

I converted a regular starter to stiff about a month ago and I find it is much easier to manage. I skipped the liquid starter step and went directly from a rye regular to white bread flour stiff. The bread doesn’t taste sour to me at all. It makes great bread. I took a piece with my on vacation in my checked luggage on an airplane. That evening I mixed a dough using my friends American AP flour that afternoon. Continued the bulk fermentation in the fridge over night and baked a beautiful bread the next evening for dinner. The stiff starter is so much more forgiving and easier to work with, except for the need to knead it. Thank you Hendrik I have learned a tremendous amount from you on my year long sourdough journey. PS. I have some sourdough pizza cold fermenting right now after feeding that starter one more time with the same unknown AP flour.

Very interesting video. One question: for how many cycles would you recommend to go through to go from normal to fluid to stiff? Thank you!

[@dbpike]

I moved from Canada to Spain last May and brought my starter and recipes with me. Sadly my starter died… RIP. For the last 10 months, my attempts at bread have ended up as pancakes. Flour? Water? Temperature? Relative Humidity? Sunburn? I experimented with all to no success. However after creating a new starter with Spanish microbes and trying a stiff starter, I had my first success! After downloading (and supporting ) your book and following your great channel, I’ve learned a few things: 1) I am spoiled coming from Canada with easily accesible, high gluten flours that can withstand the bacteria of a regular starter. 2) I was using bottled water but switched to tap water. Water in the Valencia region is extremely hard. So it probably raised the pH. 3) As you indicated, the stiff starter made a great open crumb even with the local Harina de Fuersa (bread flour). However there was no tangy flavour supporting your lesson. 4) Spanish microbes, like all things here, have a different rhythm of life. It is me that needs to adapt, not my starter! My goal now is to slowly adjust the starter to find a good balance. Thanks for all of your work. It is appreciated!

[@christineboyce988]

Guten Tag. After studying what you wrote about liquified starter and the post of the young woman researcher who tested the yeasts and bacteria prevalent in their lab. Since I make sourkraut, vinegar and yogurt I suspected that I had too much vinegar mixed in to my starter and it just didn’t work. Also, your information on using unbleached flour to routinely feed the starter was a great eye opener. My new starter is active and I’m baking with it today. Oh, also keeping a separate small jar to see the rise is genius. I use it for my yeast bakes too. No more under or overproofing. Happy New Year! Gutes Backen und Herzlicher Dank !

Until last month that I bought the French flour what is WAY more expensive, but the results is very satisfying. Now I'm trying many different bags of local flour to see which one have better gluten texture and this chart help me to understand why my dough is always sticky or very sour, some even taste like beer.

[@maboo736]

I live in SE Asia and my starter is super active by day 3 because of the warm climate. Always try to get the highest protein in flour. Perhaps try mixing in All Purpose flour? It helps to lessen the sourness and give bread a more mellow flavour but still a decent rise.

Thanks! I’m fairly new to sourdough. I was wondering why some people’s videos are showing a soft, wet starter versus what I have. I have a fairly thick starter. It is like “the blob” and it seems to work well for me. I have a very simple way of using it and I don’t have to work with the dough much. I just make regular soft sourdough because my oven and my home cannot tolerate the very hot oven. So I’ll do things a little differently and it’s working out.

[@wesnoble510]

Nice explanation. One thing that would be interesting to overlap is the seed quantity- essentially the ratio of leftover to new flour amount combined with different water amounts. In my case I’m realizing that by maintaining the regular starter method for a few days I almost completely lose the acidity. I’m guessing the yeast outcompetes the bacteria and then nearly vice versa. Maintaining the balance over time is tricky.

[@beaverschaeren5036]

[@Docjouls]

I love your bread engineering and science, Hendrik. I live in hot and humid Singapore, where I experience humidity as high as 84% and temperatures as high as 35C. Should I follow your recipe but reduce the timing by 1/3 because the starter should be more active and energetic? I also have a fermentation fridge where the temperature is between 18C and 20C. How should I tweak your recipes for hot and humid Singapore? By the way, I am learning sourdough bread for an Austrian friend who will bunk at my place for 4 months...

Amazing simple lecture for starter , I have a request , do you have and good description for quantities of starter for my bakery , we are in Middle East using factory yeast and I decide to change , thank you

[@drmarxx]

Now the big question is how to adjust your recipes for stiff and liquid starters. Do you use the same recommended percentages for a starter? Also you have to take hydration into account. Thanks

[@the_bread_code]

Correct and great question. So for 500g of flour I'd be using 50g of liquid starter. I'd also treat the 50g like water. Your dough becomes more wet by applying it. Hope that makes sense.

[@stupidhandles]

Yes! Hydration of dough is overall hydration so you need to adjust for the type of starter. One way is to start with your overall gross weight of flour, say you make a batch of 1kg flour (for ease of maths as an example) 80% hydration means 800ml of water. Make your starter from these, so stiff, take 100gm flour and 50ml water from your over all, so you dough mx will be 150gm starter 900gm flour 750mp water This is a simplified way of what I do, I use a liquid starter so have to reduce the amount of water for the dough. I find it easiest to work out gross amounts and work back. For amount of starter I base it on 20% total flour weight if using a normal 1:1 ratio starter, so that works out as flour at 10% of flour for starter. So for stiff 10% flour means 100gm flour and 50ml of water, for liquid at 1:5 flour to water 100gm flour and 500ml water, which mean you only add 300ml for water in the above example for 80% hydration. (Liquid starter I start off half the amount the day before, then around 6-8hours before mixing dough add the second half to the starter and mix your dough when the starter is good and active) (1kg flour is probably an impractical measure, I just used it as a easier way to explain the ratios, I usual do batches of 830gm flour and 664ml water, of that 80gm flour is used in starter and correct ratio of water for which starter type, I bulk ferment then split into 2lafs for final proving and bake)

I have a very mature, active and healthy starter I feed once in a while with organic rye, I took a little bit of it to make another starter with the aim to get a liquid starter, followed your formula but my starter ended up as water on top and starter at the bottom, is it a gradual process? Did I do something wrong? Thanks a lot 🙏🏻

[@stsheep]

Thanks a lot for the very useful video. However, i'm confused by one point. The liquid starter has more dairy flavor, but at the same time has higher acidity? I thought that a higher acidity will lead to a vinegary note (sour) rather than a dairy note...am i missing something?

[@perjanuschas8050]

The most interresting and informative video yet. Now how do I use this information to my advantage? I have been using a 1:1 when feeding my starter, and after a while it started smelling like tutti-frutti. A mixture of apples and pears, maybe with a hint of apricot and banana. You said yours smell like dairy? does that mean cheese and sour-cream? I think I prefer tutti-frutti over that. The breads don't smell of tutti-frutti though, but have a very pleasant taste. I may try to convert to stiff, and jump over the fluid version, as no matter what, I can't find flour that behaves like the non-stick dough you manage to create. I'll try the fluid version for kicks and grins, but my flour quality dictates baking that version in a bread baking pan... even the regular 1:1 version becomes very soft, and doesn't create as much ovenspring as yours do.

But how long do you ferment the liquid starter (with de regular starter out of the fridge) for before switching to a stiff starter?

[@IPMan-me6lo]

My first starter I made, would'n really start on day four, so I add two or three teaspoons of Stout Beer. Day five, it seems the starter liked beer, he starts to grow, and he gets a very nice flavor. After looking your video, I know now, it has to do more with the consistence too.

[@oldkingcrow777]

Im decades away from even humbly considering myself knowledgable on sourdough, but my gut logic says you could get a super fermented starter going, then when it's time to make the bread, make it a super hydrated loaf (but prepare for those unique difficulties) so the starter allows it to ferment quickly enough for your needs, but the hyper saturation with the water balances out the pH

[@gabea.2123]

I find that the liquid starter takes longer, even significantly longer, to rise a loaf; so is the more sour flavor coming from the starter or from the longer fermentation? If I use a small amount of regular (or even stiff) starter so that they all ferment for the same amount of time, will the flavor be the same? Also, I find that my liquid starter has a very strong smell, not even close to dairy. It would be great to have a way to test what kind of acid you get in a liquid starter, not just in theory, but by doing some chemical analysis in a lab to validate if you're really getting acetic or lactic acid.

You are a genius but unfortunately most people like me just can’t comprehend starting with regular starter,converting to a liquid starter then back to regular starter but maintaining the taste of the liquid starter ,so why change your starters and the lastly but always use the stiff starter even though the liquid will give you more sour notes only if you ferment longer.

[@Lagolop]

What do you consider a high amount of gluten. I use mainly AP flour (usually with some whole flour). Our AP is typically ~12%. Also, I use a regular starter. Can we simply use THIS starter but when we feed prior to baking, use different ratios starter:H2O:four to achieve different flavour notes?

[@oldkingcrow777]

Yeah I've chosen bread flour since its ideal, but I've noticed even from thr same brand, the difference is usually max 2%. Like 11.2% for AP, 12.5% for bread. I think as humans we minimize things when it comes to numbers on paper, but I'd wager that every percent +/- makes a large difference when it comes to micro flora

[@Markus1406]

What kind of flour do you use for your stiff starter? When I use rye flour there is nearly no size increase and no bubbles (of course due to the lack of gluten). Is Whole grain spelt working?

[@UniqueActive]

I have been using 100% whole grain spelt for my starter, for a few days I have been turning it into a stiff starter and it is working great, I fed it about 9 hours ago and it has almost tripled in size since then. So yes, it should work! :)

[@the_bread_code]

All flour works. But whole rye flour will soak up a looooooot of water. So in your case you might want to bump hydration up to 60% for instance.

I'm new to your channel and want to say Thanks. Do you have a step-by-step video using the sour starter with baker's percentages? I love the sour taste. The more sour, the better. I brew Kombucha and have contemplated using some of the liquid to make a starter, since it can end up with high amounts of acetic acid the longer you let it ferment. My pH from my recent batch was 2.8 and was wondering if it might work as the water portion.

[@joecaner]

I am use regular starter then. I keep my starter in the fridge and I feed it the evening before I bake. I take it out the morning of to let it proof. I add the starter to the bread flour and water mix and let that proof. I then add freshly milled rye and hydrated toasted seeds, mix and let it proof again. The results go into bread pans to rise in the fridge before baking. I am getting good rise and sour flavor. I've used the same steps for whole wheat, but I have become quite partial to seeded rye sour dough bread.

[@vorna6664]

Awesome video! :) But some questions came up watching it, especially with the graph of vol. growth and pH over time: How do you explain that the pH-value of the starter with the 25°C is decreasing faster than the 21°C one? Doesn't it somehow contradict the rule of very mild starter feeding should be done at about 27°C while a lower temp is gonna lead to a more sour taste? The next question (And maybe already kind of an answer to the first one lol :D): Do you think it is correct to see the pH-Value as one and only factor that determines how sour it tastes? I very often heard and read that it is actually the ratio between lactic acid and acetic acid what is important for the taste. Commonly the ratio is between 3:1 and 4:1. A ratio near 3:1 leads to mild flavor, while an increasing amount of acetic acid vs. lactic acid leads to a more sour flavor. No smart-assery, just exchange of ideas between nerds :D

[@the_bread_code]

Great question! Please keep all the questions coming, it's good to have a healthy discussion. 1) Regarding the temperature. I could not find a relation between a colder temperature and a more sour taste. I have testing 21°C vs 25°C in an experiment last year. Maybe the difference is not big enough. 2) Correct! Lactic acid is actually more sour on the pH scale, but when tasting it, it seems milder. Quite an awesome thing if you ask me. So assuming you have 2 doughs, one with only lactic acid, one with acetic acid, both have the same pH in the end. Then the acetic dough will feel a lot more sour when tasting it!

[@vorna6664]

@@the_bread_code 1) Yeah I agree, the difference may be not that big for one feeding only. I definitely encountered a difference when baking the recipe 'Mildes Weizensauerteigbrot' from plötzblog. The starter is refreshed 2-3 times at 27°C and also bulk fermentation is being done at this temp. That makes the bread tasting very mild already. When I used the rest of my starter for a 2nd bread some days later - same routine - I ended up with a bread with absolutely no sour flavor at all. It tasted really boring. I unfortunately have no pH meter but it would be really interesting to know what pH-value it had. 🤔 2) Awesome that makes totally sense to me. Thank you! 🙃

I have a question. My last sour dough starter which was a 50/50 became super sour and vinegary after a couple of months of use. So much so I ended up throwing it out. I have just started another one but wondering why did this change occur and it is possible to repair?

[@Eldeirdro]

Do you mix the liquid starter before you use it to make your regular starter? Or do you just use the liquid on top?

[@the_bread_code]

I shake it and then use it. If you want, you can make a sauce from the top liquid. It is excellent for hot sauces 🤗. Most of the microorganisms are close to the food, at the bottom.

[@antoniodean9171]

Does the bacteria eat the protein or the acidity produced decreases the pH and when it reaches to a pH around 4 the protease enzymes befing to break down the protein

[@MrDaddiecool]

Thank you Hendrick, very interesting. I was thinking that the sourness in the actual bread would then depend on the length of fermentation rather than the pH of the starter. Isn't the actual bread dough just like a new, bigger starter?

[@the_bread_code]

That's correct. But some starters will create acidity faster. If you look at a given volume increase you will see a different level of sourness 😎

[@oldkingcrow777]

Life trips me out sometimes, and I stopped believing in "coincidence" long ago. As I read his response to the original comment I hear thr video say regardless of the starter "the longer you let the loaf ferment, the more the acidity will build up" 😂

[@zuckmedic]

What if you mix the stiff and the wet after making the starter for the next loaf?

[@rko1095]

My starter is 3 parts bread flour, 1 part rye flour and 1 part whole wheat flour. I use distilled water instead of tap water as tap water contains Chlorine or Chloramines (Chlorine and Ammonia) which can hurt your yeast and bacteria. If you can't get distilled water (usually from your grocery or pharmacy) you can just leave tap water in an open container overnight to degas the water. The last thing I add as a little sugar to the mix to give the yeast and bacteria some extra food. I make a stiff paste in a mason jar and store it in the refrigerator. I feed it every week or so by removing half of the starter and adding flour, water and sugar in the same portions. When I want to make a loaf, the night before, I take about half a cup of my starter out and put in into another jar with half a cup of bread flour, a teaspoon of sugar and enough distilled water to make a thick paste. I leave the lid on loosely and put it on the counter overnight. By morning it has risen to about triple its size and is ready to be used in my bread.

[@oldkingcrow777]

I don't worry about using tap water, but if I'm in a purist mood I'll use filtered from the Zero filter. Life is amazingly good at continuing. The chlorine in most taps, and mine at least, isn't nearly concentrated enough to beat out the starter which was essentially pure culture at the time of drying. The chlorine didn't stand a chance 😂 That said, if I lived in Flint, Michigan I would probably go for bottled/distilled 😂😬

[@rogercoomber9598]

Very interesting, will have to try the stiff starter as the best flour I can get is 11.5% here in 🇳🇦

[@the_bread_code]

Stiff starter will work great 👍

[@sabinamauri7423]

I have just separated my starter in 2, to test the liquid version. I think it is also becoming acid because I keep to much of it when I refresh, I recently discovered that only a teaspoon is enough . Let's see how this change will affect taste

[@mohjl7752]

I already change my regular starter to liquid starter for 3days,but it still taste vinegary and sour i feed it twice in a day for 5g starter 30g bread flour 150g water . Have any solve for my vinegary starter(it too sour break my sourdough gluten at all)

[@unblockme4178]

We love very sour bread. How long should I firment???

[@simplybeautifulsourdough8920]

For bulk fermentation, I would just stick with the standard so as not to risk over fermenting. One trick to get a more sour taste is to leave the shaped dough in the refrigerator for cold proofing longer, say 24 to 48 hours.

[@yamanpant]

Very helpful. Thank you

[@janeahrens572]

Can you raise the dough outside the refrigerator and be successful? And if so, how long? I realize I’m maybe being lazy but, I have watched a lot of your videos and didn’t catch that information

[@the_bread_code]

Definitely. Sometimes I have it for a week outside of the fridge. If you mean a bread dough, you can shape it and then wait until the finger poke test passes.

[@toppefall]

Was about to ask whether it could be a fun experiment to combine liquid and stiff starter in a dough to get a high yeast high lactic acid combo with less acetic acid bacteria, but I guess you somewhat achieve the same by turning your liquid starter into a stiff starter?

[@AZZapper11]

I really like your conclusions. To me is a question of Oxygen. Anerobic (alcohol) or Anerobic (Vinegar) and all in a High Protein (more than 12%) or low Protein (Less than 10%). So I always ask my self, how much vinegar (acidity) am I making.

[@Deeber65]

I'm curious about something: Has anyone tried using a precise but smaller mix of two starter types (stiff AND liquid) in their bread batch? So, less of each type but still totaling the overall "standard" amount of starter. Not sure how that might work -- but wondering if that would result in a more pronounced sour flavor (from liquid starter) but with the fluffy attributes of a stiff starter. Thoughts??

[@momepenni]

Could you do a video on gluten free bread recipe. I know it’s not your forte. I came across an interesting flour, einkorn flour. Check it out. What percent would be flour that says 3g. The flours here doesn’t say the percentage. So I don’t know how much flour. Sorry for so many questions.

[@the_bread_code]

I hope this will help: kzbin.info/www/bejne/qXObYoKCjpdogNE. No worries at all!

[@momepenni]

@@the_bread_code Thank You, I will watch it.

[@C00ltronix]

Here is a question: When go high hydration > low hydration to get my stiff starter the lactic flavor, will it not go back to acidic eventually?

[@the_bread_code]

Great question! Nope, it won't :-). It's also dangerous of course. Acetic flavour can be great for hearty rye breads. So you will definitely change your flavour. It might be worth preserving a bit of starter by drying it.

[@C00ltronix]

@@the_bread_code Thanks. My idea is to have two starters, one for the hearty breads, one lievito madre mild type for baguette and those type of milder taste bakes.
