What is Fermaid K? And Why/When do we use it?


Femaid-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 and inactive yeast. The unsaturated fatty acids and sterols provided by Fermaid K are important survival factors yeast cells need to maintain alcohol resistance and permease activity, and help keep volatile acidity levels low. Nitrogen is critical for protein synthesis and to maintain cellular growth. Fermaid K’s alpha amino acids provide a nitrogen source which is easier and more efficient for yeast to metabolize than nitrogen from traditional ammonia salts. The cell wall fractions in Fermaid K absorb short and medium chain fatty acids that are toxic to yeast, and provide nucleation sites to help keep the yeast in suspension.

Fermaid K is like the power bar they hand out to runners at the last mile. The power bar gives you the energy and nutrients get through those last few miles of the race.

You can add Fermaid-K at 8 Brix
