Harvested Slurry Pitch Rate Calculator

Calculator Instructions: Optimize your harvested yeast slurry with precision-level accuracy. This slurry‑specific calculator refines yeast pitching by modeling harvested slurry as the yeast source instead of packs/starters. This helpful tool for beer brewing professionals estimates whether your slurry meets your target pitch rate (M cells/mL/°Plato) for a given wort volume and gravity. Enter slurry volume and cell density to confirm the number of viable cells ready for pitching. If your slurry falls short of your brewing parameters, our tool can recommend optional starter growth and repitching. Achieve consistent fermentations and flavor stability by ensuring each batch starts with the right yeast load.
