Fermaid K - Yeast Nutrient

Fermaid K is a blended yeast nutrient that supplies ammonia salts (DAP), free amino acids (organic nitrogen from deactivated yeast), sterols, unsaturated fatty acids, key nutrients (magnesium sulfate, thiamin, folic acid, niacin, biotin, calcium pantothenate) and inactive yeast. Does not contain zinc, which is needed for healthy fermentation in malt-based wort. 

Add to must at the beginning of fermentation, and again at 1/3 sugar depletion for high nutrient requirement yeasts. Add at the rate of 1 gram per gallon. Fermaid K can be added directly to must, or if the fermentation is active, hydrate in water to avoid CO2 release and excessive foaming.

Usage: 1 gram per gallon.
