Yeast Pitch Rate Calculator

Estimate your pitch target by batch size, gravity, and yeast type.

12.0 degrees Plato

Default is 75%, matching the average public attenuation range across the current ale and lager catalogue.

About pitch rates

The calculator shows three pitch-rate choices for ales and lagers. We mark the full commercial pitch as recommended, while still letting you model a moderate or lower pitch rate if that suits your process.

Enter gravity as SG or Plato. The calculator uses Bluestone's commercial liquid yeast concentration of greater than 2 billion cells/mL to estimate fresh yeast volume. ABV is estimated from original gravity and apparent attenuation. Treat both outputs as planning tools; we confirm final order volume against strain, gravity, timing, and brewery process.
