Sourdough bread is made by the fermentation of dough using naturally occurring lactobacilli and yeast.
Sourdough bread has a more sour taste and better inherent keeping qualities than breads made with baker's yeast, due to the lactic acid produced by the lactobacilli.
In order to make your own sourdough bread, you need to make a sourdough starter. If you want to learn how to do your own sourdough starter and bread click here: HotToMakeSourdough
