Pitch Rate & Starter Calculator
Calculate pitch-rate targets, estimate viable yeast cells from package age and viability, and size a starter to hit your cell count goal with DME addition.

What this yeast calculator does
Use batch volume, original gravity, pitch-rate target, yeast form, viability, and starter size to estimate required cells and whether your starter reaches the pitch target.
Pitch-rate presets
The presets mirror common brewing guidance: minimum, standard ale, high-gravity ale, lager, and high-gravity lager rates in million cells per ml per degree Plato.
