Lalvin K1™ (V1116) has been selected by INRA Montpellier located in France in the Mediterranean region. When fermented at low temperatures (below 16°C) and with the right addition of nutrients, Lalvin K1™ (V1116) is one of the yeast producing the most floral esters (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 K1™ (V1116) is the most resistant strain in difficult fermentation conditions, such as low turbidity, low temperature and low fatty acid content. Lalvin K1™ (V1116) is also a proven strain for the fermentation of ice wines.

USAGE
DOSAGE RATE: 1 x 5g sachet for 4.5 – 23L
1. Rehydrate the yeast in 50ml of water, at a temperature between 35-37°C (95-98.6°F).
2. Dissolve by gently stirring and wait for 20 minutes.
3. Add the must. The difference in temperature between the must to be inoculated and the rehydration medium should not be higher than 10°C (if necessary, acclimatize the temperature of the medium by slowly adding must).
4. The total rehydration time should not exceed 45 minutes.
5. It is crucial that a clean container is used to rehydrate the yeast.
6. Rehydration in must is not recommended.
