## Overview

Fermaid K is a premium blended yeast nutrient designed to optimize fermentation by delivering a precise 1 gram per gallon dose of ammonia salts, organic nitrogen, sterols, fatty acids, and essential vitamins. Ideal for high nutrient-demand yeasts, it’s added at the start and again at one-third sugar depletion, ensuring vigorous and consistent fermentation. Compatible with Go-Ferm for a complete yeast nutrition regimen, Fermaid K is trusted by brewers to accelerate fermentation and enhance product quality.

## 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.

Review: Super charge fermentation - Does an excellent job! I’ve added this Fermaid K to a couple gallons of must to brew Mead and in about 8 hours the fermentation took off in a supercharged style! I’ve attached a video of the active fermentation to prove it. At only 1 gram per gallon of must this stuff is definitely a “must”.
Review: Great additive that does it's job well. - Straight up product with proven record. Fermaid K is what it is. This is the second time I've ordered this product and it's worked perfectly both times.

## 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
