Packaging & Dosage

One sachet is enough to treat a single 19-23L batch.

When calculating for larger batches, use at a rate of 0.5-1g per Litre. We recommend rounding up by one full sachet rather than measuring out the yeast exactly.

Calculation for Larger Batches

• Use at a rate of 0.5-1g per Litre (approx. 50-100 g/hL).
  
• For high-gravity ales or exceptionally bright beer, increase toward 2–3 g/L
