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.

Making straight mead with only honey and water stresses your yeast. Use Fermaid O and follow the TOSNA Protocol (Google it) of staggered nutrient additions for a strong and healthy fermentation. Get a better finished mead a lot quicker.
Great nutrient that keeps the ferment going strong right to the end! I even cut the rate a bit. Difficult to dissolve into solution before adding though.
