Lalvin ICV K1-V1116 was initially isolated in 1972 by Pierre Barre of the INRA Montpellier. When fermented at low temperatures (below 16°C) and with the right addition of nutrients, Lalvin ICV K1-V1116 is one of the most floral ester-producing yeasts (isoamyl acetate, hexyl acetate, phenyl ethyl acetate). These esters bring fresh, floral aromas to neutral varieties or high-yield grapes. Among the high ester producers, Lalvin ICV K1-V1116 is the most resistant to difficult fermentation conditions such as low turbidity, low temperature, and low fatty acid content. Lalvin ICV K1-V1116 is a proven strain for the fermentation of ice wines. It can also be used for rosé or red wines.

Note: dosage range is based on the must sugar content and sanitary state of the grapes and winery.

HOW TO USE

Rehydrate Lalvin ICV K1-V1116 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.

Notes:
– 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)
– It is essential to rehydrate the yeast in a clean container.
– Initial rehydration in must is not advisable.
