Whole Grain Poolish/Biga Formula
Looking for a formula that does not use a mature sourdough starter but instead a biga/poolish type of preferment, but also has whole grain flour or at the very least whole wheat flour. I have looked through the site and can not really find much whole grain/whole wheat breads that use a non-sourdough starter preferment. Maybe there's a reason for this?
Formulas with any of the following flours would be appreciated:
Spelt, Stone ground whole wheat, Whole wheat, Rye
