*If your pitch is for a propagation starter, switch to Propagation above — the dose is doubled automatically.
How this is calculated
  • Wort gravity (°Plato) and Specific Gravity are linked and update each other automatically as you type.
  • Recommended pitch size (Trillion cells) = pitch rate (M cells/mL/°P) × batch volume (mL) × wort gravity (°P) ÷ 1,000,000.
  • Litres of slurry is a rough approximation assuming ~2 trillion cells per litre of cropped yeast.
