Fermaid K is a blended complex yeast nutrient that supplies ammonia salts (DAP), free amino acids (organic nitrogen derived from inactivated yeast), sterols, unsaturated fatty acids, key nutrients (magnesium sulfate, thiamin, folic acid, niacin, biotin, calcium pantothenate) and inactive yeast. For best results, Fermaid K should be used in conjunction with an appropriate yeast rehydration nutrient (such as Go-Ferm or Go-Ferm Protect) to assure proper nutrition of cultured yeast from rehydration through completed fermentation. Add 25 g/hL at 1/3 sugar depletion or in two doses; 12.5 g/hL at the end of lag phase and 12.5 g/hL at 1/3 sugar depletion.
Fermaid K provides unsaturated fatty acids and sterols. These are important survival factors needed to maintain alcohol resistance and permease activity. They also help keep volatile acidity levels low.
