FERMAID O™

Organic nutrition (100 % yeast autolysate)

FERMAID O™ is from 100% yeast autolysate, 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™? or GO-FERM PROTECT™? and FERMAID O™ is recommended. With this combination, GO-FERM™ or GO-FERM PROTECT™ 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.
