Work out yeast quantity instantly with clear inputs, formula shown and shareable results.
The dose is set as a baker's percentage of the flour for instant yeast, then converted: active dry needs about 1.25 times as much and fresh yeast about three times as much. Yeast type substitution is where most bread recipes go wrong, because swapping fresh for instant gram for gram triples the leavening.
Instant yeast
instant yeast grams = flour x yeast percentage
Substitution
active dry = instant x 1.25; fresh = instant x 3
instant yeast grams = flour x yeast percentage. The dose is set as a baker's percentage of the flour for instant yeast, then converted: active dry needs about 1.25 times as much and fresh yeast about three times as much.
