Second round of sprouted wheat, slightly adjusted recipe this time: working with both sprouted wheat and rye berries, switched out about 30% of the water for beer. Sourdough starter wasn't as active, but the flavor was even nicer than last weekend's batch.
100% whole wheat, like you were trying before, is doable but not especially palatable imo. The one I'm working on up there ^ is 40% ww, and one bread we used to do was 80% (although it did use commercial yeast and wasn't sourdough) and actually really, really good. Here's that recipe, if you're interested in trying it.
Code:
12-hour poolish:
Water 144% 128g
Whole Wheat 100% 90g
Yeast 1% 1g
Dough:
Poolish 45% 219g
Whole Wheat 80% 386g
High Gluten 20% 96g
Salt 2.5% 12g
Yeast 0.2% 1g
Water 68% 328g
Mix the poolish the night before (or early in the day), keep it in a large enough container because it's going to double or even triple in size. When you mix the dough, leave out the salt and yeast initially. Mix 4-5 minutes on low, then bump up to a medium speed for about the same time. Add the salt and yeast during the second period. Into an oiled or sprayed container, give it a fold every half hour for 90 minutes (so 3 folds total) and then let it sit for a couple hours. Should be good to go by then.
