    Is the starter feeding ratio 1:5:5 above an error? If not, when does 1:2:2 apply and when does 1:5:5 apply? Thanks for this excellent article.

    • Well, once you want to optimize your starter, feeding 1:5:5 is more effective. When it triples in a feeding you have enough yeast in your starter, then you should use feeding proportions to time when to use your starter.

      If you want to bake a quickly as possible, feed it 1:1:1, if you want to let the starter grow overnight you’d feed it to stretch the growing out over the whole night.

      Watch my timelapse here what difference it makes: 🙂

    Hi. I enjoy this blog and appreciate your guidance and expertise. Thanks for the advice about putting a baking stone on the bottom rack of the oven. I’m new to baking bread and use a Dutch oven. I’ve been struggling to get the loaves nice and dark, which I prefer, without burning the bottom crust. I’ve moved the DO to the next rack up after the first 20 minutes, and that helps, but it’s a real pain to do mid-bake.

    I just baked a loaf of white, whole wheat, and dark rye sourdough, and it turned out beautifully. I got great oven spring, a gorgeous crackling crust on the top and sides, and no scorched bottom crust. Now I just need to be patient and wait another hour before I can cut into it.

    • I’m glad that it’s working for you. Domestic ovens are pretty fickle in how it heats, and figuring out where to bake in your particular oven can be a bit of a struggle 🙂

    Hi Sune, I have a question about building my starter, which you talked about in this article.

    You mentioned 1:5:5 at 5g:25g:25g as a way to build up strength, and also a 3-feed schedule (6:00/6 a.m., 14:00/2 p.m. and 22:00/10 p.m.)

    At 6am you do the 5g:25g:25g, then once it’s peaked do you take out 5g and do another 5g:25g:25g at 2pm and the same at 10pm?

    The next day when you want to make bread, do you do a 1:5:5 on what you need for baking, so if I need 100g for baking, I would mix at 6am a 9g:45g:45g?

    • You may wanna make a bit more so you don’t bake off your starter in the bread.

      Do a 12g:60g:60g so you have a little bit of starter to keep the starter going 🙂

    Thnx for the tips, most of them i am already aplying. One thing that really triggered me was the scoring and baking the cold dough, as i read somewhere else that you should not because the crumb will not set. Neverheless i have usually a reasonable bread but it will not spring as much as i want. Do you mean with cold straight from the oven or like half an hour/hour out of the fridge in comparison with the 2,5, 3 hours most recipies recommend?

    Do you spray the dough with water before placing the cover on and placing in the oven?

    • I don’t usually, but it makes these gorgeous blisters on the bread, so do it if you want that 🙂

    For what length of time do you retard the shaped loaves in the frig before putting them directly into the oven?

    • Often about 8 hours, but sometimes days, 2-3 days is fine 🙂

    Which is it, 1;2;2 or 1;5;5?

    • When optimzing your starter for maximum yeast. After it’s established use whatever proportion that fits with when you need your starter to be ready 🙂

    Thanks for the tips, they have been very helpful. I read you place dough in refrigerator for up to 36 hours. How do you keep the dough from overproofing? Also, do you bake directly from the fridge or let the dough come to room temperature first?

    Ever tried a slightly smaller granite slab on bottom of Dutch oven to create a reservoir for boiling water.

    • No, but I’ve never had to add water to the dutch oven 🙂

    I had been baking sourdough bread for about 3 years. I thought I was happy with the outcome, until I saw your bread! I have been using your Master recipe for Artisan Sourdough bread for about 3 months now and am absolutely amazed with every loaf. They come out beautiful and light and wonderful open crumb. Thank you! I have shared the recipe with friends and family.
