Diammonium Phosphate – DAP

Diammonium Phosphate (DAP) is a mineral nitrogen source used for yeast viability during primary fermentation.  DAP stimulates yeast growth and fermentation activity and helps to prevent the formation of hydrogen sulfide.  Add it to wort prior to fermentation. We also recommend an addition of organic nitrogen sources (Springferm) for its vitamins and minerals. ATP carries both domestic and import product.
