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 is generally considered wild yeast, though the flavor of sourdough is actually from a mixture of yeast and lacto-bacteria. Once a stable culture has been created, the amount of leavening gas is produced roughly equally by the yeasts and bacteria.hen making sourdough for the purposes of acid-base leavening, such as pancakes, a more-acid dough is often desired. A simple way for a baker to achieve that using accurate measurement and formula notation is to use an excessively high starter percentage. Generally, sourdough improves with age.
