Yeast Nutrient, Fermaid O - 1 oz

Fermaid O is the latest nutrient developed by Lallemands winemaking nutrient research team headed by Dr. Anne Ortiz-Julien. Fermaid O is a blend of inactivated yeast fractions rich in organic nitrogen. Fermaid O does not contain added ammonia salts (DAP) or added micronutrients.

The importance of organic nitrogen from yeasts is well known as a highly efficient nutrient source forwine yeasts, especially when compared to inorganic nitrogen from DAP. In addition, Fermaid O consistently produces lower levels of negative sulfur compounds, compared with DAP. With its high content of organic nitrogen, Fermaid O can help winemakers achieve steady fermentations, while limiting temperature peaks. When inorganic nitrogen (DAP) additions are NOT desired, the use of Go-Ferm® or NATSTEP™ and Fermaid O is recommended. With this combination, Go-Ferm or NATSTEP provides needed micronutrients during yeast rehydration, and Fermaid O supplies critical nutrients andsurvival factors to help the yeast avoid stressed conditions. Note: In low nutrient situations, yeast available nitrogen (YAN) may be insufficient to avoid fermentation problems.

Usage Rate: 1.5g/gal wort. Dissolve in a small amount of wort or water gefore adding to fermenter.
