A complex formula that provides DAP, free amino acids, yeast hulls, unsaturared fatty acids, sterols, and micronutrients such as magnesium sulfate, thiamin, folic acid, biotin, calcium pantothenate, and other vitamins and minerals. Yeast use Nitrogen for protein synthesis and to maintain cellular growth. Nitrogen from the alpha amino acids contained in Fermaid K is utilized much more efficiently than from the ammonia salts. The unsaturated fatty acids and sterols available in Fermaid K are important survival factors needed to maintain alcohol resistance. They also help keep volatile acidity levels low. The cell wall fractions, available through the included yeast hulls, absorb medium chain fatty acids that are toxic to the yeast. They also provide nucleation sites to help keep the yeast in suspension. Fermaid K is normally used in conjunction with GO-Ferm and added to the fermenting wine after 1/3 sugar depletion. Our Winemaking consultant Shea Comfort uses the analogy of a marathon to describe when to use nutrients. GO-Ferm is the snack before the race and Fermaid K is the mid-race power bar that gets your yeast through a healthy, problem-free ferment. It is a formula used by hundreds of commercial wineries. 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.
