Character

  • Balanced fruity and floral notes
  • Fast fermentation
  • Strong flocculation and fast sedimentation for bright beer
  • Copes with highly hopped ales

Fermentis specification

  • Pack: 11.5g sachet
  • Temperature: 18-26°C
  • Apparent attenuation: 74-82%
  • Alcohol tolerance: 9-11%
  • Dosage: 50-80g per hectolitre, so one 11.5g sachet is the minimum dose for 23 litres

How to use

Sprinkle evenly over the wort surface, or rehydrate in ten times its weight of sterile water at 25-29°C for 15-30 minutes. Store sachets below 24°C for up to 6 months, or below 15°C for longer. Once opened, reseal, keep at 4°C and use within 7 days.

A natural partner for Maris Otter malt and English hops like Fuggles. Also handy for replacing the yeast in a beer kit. See the Fermentis yeast range or compare every beer and cider yeast we stock.
