Fermaid® O is certified organic by OMRI. 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.
Storage: Store at 18°C(65°F). Once opened, keep tightly sealed and dry.
Usage rate is 2-3 grams per gallon of wort, must, etc. There are some differing opinions about how much should be used and when, but one good resource for accurate dosing in Mead Must is www.meadmaderight.com
