Fermaid O Yeast Nutrient
Fermaid O is an Organic version of Fermaid K. It is an autolyzed yeast nutrient with a high content of organic nitrogen (amino acids). It is formulated without DAP. It is best to add Fermaid O in two doses. Add half the dose at the end of lag phase (at the onset of fermentation) and the other half between 1/4 and 1/3 sugar depletion.
To Use: Fermaid O should be mixed with room temperature water before adding to an active fermentation to avoid CO2 release and overflowing of tanks or barrels. The amount of water used is not critical. Simply add enough to make a slurry.
Dosage: 1.5 grams/gallon
Storage: Dated expiration. Store at 18°C(65°F). Once opened, keep tightly sealed and dry.
Had a hard cider and a citrus ginger beer that were both just kinda limping along. I added some Fermaid O and could tell a noticeable difference in fermentation within an hour. Not quite sure how it affects taste (if at all), but it definitely seemed to help with fermentation quite a bit!
