Fermaid O

Fermaid O is a highly efficient yeast nutrient and source of organic nitrogen. It’s used to achieve steady wine fermentations by compensating for deficiencies in nitrogen and micronutrients in the must (unfermented wine).

Fermaid O is a newer formulation of Fermaid K. The main difference: this product does not contain inorganic nitrogen like Diammonium phosphate (DAP) or ammonia salts. The organic nitrogen in this product is easier for wine yeast to digest, which yields a more consistent fermentation.  

Fermaid O also helps yeast produce less heat during fermentation compared to yeast nutrients with DAP. Fewer heat spikes during fermentation reduces the level of negative sulfur compounds (and resulting off-flavors) in wine.

Fermaid O enhances ripe fruit character while decreasing dryness sensation on the palate. 

Recommended dosage is 1.5 grams per gallon of wine. Best if added in 2 doses: half at the end of the lag phase, and the other half once the sugar content is depleted by 1 ⁄ 3 of original gravity (calculate gravity changes with a hydrometer ). Before adding the second dose to an active fermentation, mix with room temperature water to avoid excess CO2 release and overflow.

For best results, this product should be used with a yeast rehydration nutrient like Go-Ferm to assure proper nutrition.

Package contains 1 Oz of Fermaid O.
