Autolyzed yeast nutrient without DAP
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: Dated expiration. Store at 18°C(65°F). Once opened, keep tightly sealed and dry.

Very effective as a source of nutrients for yeast, and I would highly recommend using this instead of DAP. The only thing I would recommend is to split up additions into quarters instead of halves. The product is also rather sticky and comes in a bag. I would recommend moving it to a mason jar.
