Product Overview

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.

For best results, Fermaid K should be used in conjunction with an appropriate yeast rehydration nutrient (such as Go-Ferm or Go-Ferm Protect) to assure proper nutrition of cultured yeast from rehydration through completed fermentation. Add 25 g/hL at 1/3 sugar depletion or in two doses; 12.5 g/hL at the end of lag phase and 12.5 g/hL at 1/3 sugar depletion.

Fermaid K provides unsaturated fatty acids and sterols. These are important survival factors needed to maintain alcohol resistance and permease activity. They also help keep volatile acidity levels low.

Nitrogen is needed 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 cell wall fractions in Fermaid K absorb short and medium chain fatty acids that are toxic to the yeast. They also provide nucleation sites to help keep the yeast in suspension.

To Use
Fermaid K should be mixed with room temperature water before adding to an active fermen­tation to avoid CO2 release and overflowing of tanks or barrels. The amount of water used is not critical. Simply add enough to make a slurry.

Storage
Dated expiration. Store at 18°C(65°F). Once opened, keep tightly sealed and dry.

Recommended Dosage
1 g/gal    25 g/hL 2 lb/1000 gal

Smart brewers know that a yeast starter is the best way to ensure proper cell count and yeast viability prior to pitching. If you want a reliable starter for your batch of beer, you need to feed the yeast. Adding a yeast nutrient to the starter will give the yeast an added boost! Fermaid K is a yeast nutrient that works for starters and main fermentation. Here’s how it works:
 
Fermaid K is a complex formula that provides DAP, free amino acids, yeast hulls, unsaturated 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 like DAP. 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. 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.
