## Overview

Fermaid K is a premium, vegan yeast nutrient powder designed for winemakers and brewers. It delivers a scientifically balanced blend of ammonia salts, organic nitrogen, essential vitamins, and sterols to optimize yeast health and fermentation performance. Applied at 1 gram per gallon, with a critical second addition at one-third sugar depletion, it ensures vigorous fermentation and superior flavor development while minimizing foaming when hydrated properly.

## 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.

## Features

- Complex yeast nutrient
- 1 gram per gallon of must or juice
- 80 g (2.8 oz)
- Rehydrate in distilled water and add after 1/3 sugar depletion
- Use with Go-Ferm for a complete yeast nutrition schedule

## Questions & Answers

**Q: The description mentions organic nitrogen, does this mean this product could be called the  'O' version?**
A: Fermaid O vs. Fermaid K has replaced the inorganic DAP (Diamonium phosphate) with an organic source. The manufacturer suggests it will result in lower heat output from the yeast, and lower levels of negative sulfur compounds. Straight DAP is like feeding your wine a "twinky" rather than a balanced diet. The organic compounds are consumed thus the "O" version you mention. I use it in whites, reds and fruits wines. Make the yeast happy and you'll make good wine.

**Q: This works for meads? I make mead for celiac people, could i use this product?**
A: Absolutely works for meades.  In fact the staggered dose is the recommended method.

**Q: Is this gluten free?**
A: According to the manufacturer the product is Gluten free.

**Q: How is this packaged?  Small bag?  small bottle?**
A: Small bag, that you need to repackage into something after opening. i just used this and blended with go-ferm to make a blend
