Premier Classique is the same yeast that was formerly called Montrachet yeast. Using Premier Classique dry yeast guarantees a quick start of the fermentation. Good alcohol resistance (till 15% vol.), large temperature range (15°C to 35°C, 59°F to 95°F). Ideal strain for big volumes of wine when looking for a secure fermentation.This is a great all-purpose yeast strain, especially good for non-grape wines and Concord grape wines.
