Sourdough or sourdough bread is a bread made by allowing the dough to ferment using naturally occurring lactobacillaceae and yeast before baking. The fermentation process produces lactic acid, which gives the bread a sour taste and improves its keeping-qualities.[1][2]
Sourdough is one of the most ancient forms of bread, and it was the standard method of breadmaking for most of human history. It was replaced by barm during the Middle Ages, which was then replaced by industrially produced baker's yeast in the late 19th and early 20th centuries.
