Making a Yeast Starter

  • Add 1/2 teaspoon of sugar and the contents of the sachet to a glass with about 50ml of warm water. (approx. 20 °C)
  • Cover the glass with a clean plate and simply leave for 15-20 minutes.
  • Before you empty the glass of yeast into your brew we recommend vigorously stirring your wine.
  • The more oxygen introduced before you put the yeast on will promote a strong healthy fermentation.
