[1] Sourdough bread relies on a wild yeast starter rather than commercial baker's yeast. [2] This starter, a fermenting mixture of flour and water, captures wild yeasts and beneficial bacteria from the environment. [3] Over time, these microorganisms produce carbon dioxide and lactic acid, giving the bread its characteristic rise and sour flavor. [4] Many commercial bakeries prefer using dry active yeast because it is faster and more predictable. [5] Once the starter is active, it must be regularly fed with fresh flour and water to keep the yeast alive.
