Sourdough is a dough containing a Lactobacillus culture in symbiotic combination with yeasts. It is one of the principal means of biological leavening in bread baking, the others using cultivated forms of yeast.It is important in baking rye-based breads, where yeast does not produce comparable results.read made from 100 percent rye flour, which is very popular in the northern half of Europe, is usually leavened with sourdough. Baker's yeast is not useful as a leavening agent for rye bread, as rye does not contain enough gluten.
Sourdough breads are made with a sourdough starter (which differs from starters made with baker's yeast). The starter cultivates yeast and lactobacilli in a mixture of flour and water, making use of the microorganisms already present on flour; it does not need any added yeast.read is also made from the flour of other wheat species (including durum, spelt and emmer), rye, barley, maize (corn), and oats, usually, but not always, in combination with wheat flour.
