Fermaid O™

Fermaid O™ is the latest nutrient developed by our 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 micronutrients. The importance of organic nitrogen from yeasts is well known as a highly efficient nutrient source for wine yeasts, especially when compared to inorganic nitrogen from DAP. In addition, Fermaid O™ consistently produces lower heat of fermentation and 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 PROTECT EVOLUTION and Fermaid O™ is recommended. With this combination, GO-FERM PROTECT EVOLUTION provides needed micronutrients during yeast rehydration, and Fermaid O™ (when added at 1/3 sugar depletion) supplies critical nutrients and survival factors to help the yeast avoid stressed conditions. Note: In low nutrient situations, yeast available nitrogen may be insufficient to avoid fermentation problems. Dosage recommendations: Add 40 g/hL (3 1/2 lb/1000 gal) of Fermaid O , 20 g/hL at the end of the lag phase and another 20 g/hL around 1/3 sugar depletion.
