Rehydration instructions:

  • Sprinkle the yeast in minimum 10 times its weight of sterile water or wort at 25 to 29°C (77°F to 84°F).

  • Leave to rest 15 to 30 minutes.

  • Gently stir for 30 minutes, and pitch the resultant cream into the fermentation vessel.


  • Pitch the yeast directly in the fermentation vessel providing the temperature of the wort is above 20°C (68°F). Progressively sprinkle the dry yeast into the wort ensuring the yeast covers all the surface of wort available in order to avoid clumps.

  • Leave for 30 minutes, then mix the wort using aeration or by wort addition.
