Fermaid O 1#

FERMAID O™ Yeast Fermentation Nutrient

Fully organic yeast nutrient to sustain active yeast and support clean fermentations; OMRI listed
FERMAID O™ is a 100% yeast-derived nutrient that supplies nitrogen as a balanced mix of amino acids and peptides, along with naturally occurring sterols, lipids, vitamins, and minerals to support steady fermentation.

Rather than driving rapid early uptake, the amino acid profile is assimilated more gradually and can be stored and used by the yeast later in fermentation. This helps maintain a population of metabolically active cells through to dryness, reducing the risk of late-stage slowing or deviation.
Balanced amino acid nutrition supports sustained yeast metabolism
Promotes steady kinetics throughout fermentation
Supports clean aromatic expression by maintaining balanced yeast metabolism and reducing stress-related off-aromas
FERMAID O™ was developed to sustain yeast performance over time, supporting a healthy and metabolically capable population.
Frequently used in: Reds, whites, rosés, and ciders with medium or high YAN. Can be used in low YAN situations in conjunction with STIMULA nutrients
When to add: 2-3 °Brix drop and/or 1/3 sugar depletion
Provides: YAN in the form of organic nitrogen
Recommend Dosage: 10-40 g/hL (0.83-3.3/1000 gal)
*Measurable YAN at 40g/hL: 16 ppm
*YAN equivalents at 40g/hL: 64 ppm

Usage: Suspend FERMAID O in water or juice/must and mix well before adding, especially during fermentation to avoid CO2 release and overflowing of vessel.
Storage: Dated expiration. Store at in a cool and dry environment at 18°C (65°F). Once opened, keep tightly sealed and dry.
