Sourdough bread is a type of bread that is produced by fermenting a dough with wild yeast and lactic acid bacteria, which inhabit the flour and water starter. This fermentation is slow and allows for the bread to develop its iconic tang and chewy crumb and crispy crust gingerly. Since sourdough is one of the oldest types of leavened bread, it has its own unique flavor, longer durability, and possible chances for aiding digestion.
