What Is Brewer’s Yeast?

Brewer’s yeast is a single-celled yeast (Saccharomyces cerevisiae) used in fermentation. After the brewing process, the yeast can be separated and dried. This product is inactive (deactivated), which means it does not behave like baking yeast and isn’t used to make dough rise. Instead, it’s used as a dried yeast ingredient that can be mixed into foods and drinks.

Searching for inactive yeast for baking or sourdough?

Some shoppers look for phrases like best inactive yeast brands for baking, top-rated inactive yeast products, or inactive yeast for sourdough starters. It’s important to note that inactive yeast does not ferment or raise dough, so it is not a sourdough starter and won’t replace active yeast or live starter cultures. However, this type of product can still be used in recipes as a dried yeast ingredient (for example, mixed into foods) where you’re not relying on yeast activity for rising.
