Rehydrate Lalvin ICV-D47 in 5 times its weight of water at 40°C. Let stand for at least 20 minutes then gently stir occasionally to break up any clumps. Add to the must.

– The total rehydration duration should never exceed 45 minutes
– Avoid cold shocking the yeast. the temperature drop between the must to be inoculated and the rehydration medium should never be above 10°c (in case of doubt, please contact your supplier or Lallemand)
