How to Convert Between Yeast Types
Formula
Baking recipes call for different yeast types that are not directly interchangeable by weight. Instant yeast is more potent than active dry, and fresh yeast is much heavier.
Active dry yeast to instant: multiply by 0.75. Active dry to fresh: multiply by 3. Instant to active dry: multiply by 1.33.
Common use cases:
- Substituting yeast types in recipes
- Converting European recipes using fresh yeast
- Using packet equivalents
