Fermaid 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 and inactive yeast. It can help re-start stalled yeast or help speed up a sluggish fermentation.


  • The unsaturated fatty acids and sterols provided by Fermaid are important survival factors yeast cells need to maintain alcohol resistance and permease activity, and help keep volatile acidity levels low.
  • Nitrogen is critical for protein synthesis and to maintain cellular growth. Fermaid K's alpha amino acids provide a nitrogen source which is easier and more efficient for yeast to metaboize than nitrogen from traditional ammonia salts.
  • The cell wall fractions in Fermaid  absorb short and medium chain fatty acids that are toxic to yeast, and provide nucleation sites to help keep the yeast in suspension.


Fermaid  should be mixed with room temperature water before adding to an active fermentation to avoid CO2 release and overflowing of vessels. The amount of water used is not critical. Simply add enough to make a slurry. Hydrate and add 1/2 tsp (2g) per 5 gallons 24 hours after pitching yeast to ensure a rapid and healthy fermentation. One package is enough for approximately 15 5 gallon batches.
