SafAle S-33 is a Fermentis dried ale yeast chosen to bring out hoppy and fruity flavours. It gives beer a fuller mouthfeel and body, which makes it a good fit for Belgian ales, strong English ales and New England IPAs.

Character

  • Fruit-driven, with a medium level of esters
  • Adds body and a generous mouthfeel
  • Medium sedimentation; leaves a powdery haze if stirred up rather than clumping

Fermentis specification

  • Pack: 11.5g sachet
  • Type: top-fermenting ale yeast
  • Temperature: 18-26°C
  • Apparent attenuation: 68-72% (leaves some sweetness and body)
  • 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 onto the wort at fermentation temperature, or rehydrate in ten times its weight of sterile water at 25-29°C for 15-30 minutes, then pitch. 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.

For a spicier Belgian character try SafAle T-58; for a cleaner ale, SafAle US-05. See the full Fermentis yeast range or compare every beer and cider yeast we stock.
