Question: what is the difference between active dry yeast and brewers yeast?
Answer: Brewer's yeast is often referred to as beer yeast. ... Substitute a little less than half of the active dry yeast for the brewer's yeast, since the active dry yeast is a more concentrated form. If the recipe calls for 1 ounce of brewer's yeast, use a bit less than a half-ounce of baker's yeast.
