  • Product description

    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.

    Fermaid K is normally used in conjunction with GO-Ferm (a yeast rehydration nutrient) and added to the fermenting wine after 1/3 sugar depletion.

    The unsaturated fatty acids and sterols available in Fermaid K are important survival factors needed to maintain alcohol resistance. You do not need to add any additional fertilizers or DAP when adding Fermaid K.

    Use: approximately 1 gram per gallon. Rehydrate in distilled water.

    A rough approximate of weight is 1 tsp = 4.7 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

    Key Benefits

    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 the 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.
