Fermaid O yeast nutrient - certified organic.
While stocks last 100g (normally $30 now $20), 500g (normally $99 now $60) & 1kg (normally $150 now $80) packed down packs (not manufacturer's packaging) are on special. There is nothing wrong with the product but because the 1kg packs are out of stock we want to sell the opened larger pack faster so ensure our stock remains top notch fresh.
At the time of writing there was 1 only of the 1kg pack in manufacturer's packaging available and then are out of stock until later in 2024. 10kg in manufacturer's packaging available.
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 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.
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.
