Gervin GV4 High Alcohol Yeast (purple label) is a very tolerant, low-foam wine yeast for strong wines. Use it for high-sugar musts, strong country wines and meads where a standard yeast might stop short.

Key features

  • High alcohol wine yeast from Gervin
  • Very tolerant of high alcohol
  • Low foam
  • Purple label in the Gervin range

How to use

Prepare your must, then sprinkle the dried yeast onto the surface - Gervin say there is no need to stir. Sanitise everything that touches the must with no-rinse ChemSan first. With very sweet musts, adding the sugar in stages is gentler on the yeast.
