The open junction design is virtually impossible to clog since any deposits can be easily removed, exposing the reference cell. This tends to result in an irregular cell structure with thicker cell walls in the bread crumb and a tougher bite. ( Log Out /  In order to limit bacterial growth, the raw dough must be below pH 8. There are different ways to go about measuring it. Then again, my sourdough culture may have a lower or higher pH than LindyD's when it is ready for the oven, they may have different strains of yeasts and bacteria, all contributing to the end decision to when the loaf has finished fermenting enough to bake. It plays a roll with sourdough starters if only discards are used as a dough, the low pH if it dips 4 and under (high acid) will tell you that added yeast will not raise it. ( Log Out /  Fermenting is only part of the dough picture. Poolish is a highly fluid yeast-cultured dough. The open junction design is virtually impossible to clog since any deposits can be easily removed, exposing the reference cell. Sours that develop acidity equal to a TTA of 18-22 ml or higher with a pH of 3.8 or lower will gradually lose their ability to produce enough carbon dioxide to leaven bread loaves. This raises the pH of the lavash flour, making it a more alkaline bread. So I'm thinking that wild yeasts are more adapted to living under lower pH conditions. :).
