## Overview

Fermaid K is a complex yeast nutrient designed for winemaking, providing essential nutrients at a precise 1 gram per gallon dosage. It should be rehydrated in distilled water and added after one-third sugar depletion for optimal yeast performance. When paired with Go-Ferm, it completes a professional yeast nutrition schedule, ensuring consistent and healthy fermentation.

## Description

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. 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 grams 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.
