This nutrient blend is appropriate for use in fermentations using low nutrient need yeasts, and where the must or juice is high or medium-high in YANC nitrogen content. When fermentation conditions demand nitrogen supplementation greater than 50 ppm, DAP of Fermaid K should be added as well.
Notes about the YAN contribution of Fermaid O:
While a 1 gram per gallon (0.25 gram per liter) addition of Fermaid O will provide about 10 ppm of nitrogen, the nitrogen is more efficiently assimilated by the yeast than other inorganic sources of nitrogen such as D.A.P. You can expect about 3X (three times) the utilization of nitrogen. Therefore, a 10 ppm addition of nitrogen from Fermaid O may have a similar result to a 30 ppm addition of D.A.P.
How and when to add Fermaid O:
