Diammonium Phosphate – DAP

Mineral nitrogen source used for yeast viability during primary fermentation.

Product Specs

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.

  • Stimulates yeast growth and fermentation activity.
  • Helps to prevent the formation of hydrogen sulfide.
  • Readily soluble in water and can be added directly or as an aqueous solution.
  • Other names:  Ammonium phosphate, secondary; diammonium hydrogen phosphate; diammonium phosphate; DAP.

Application: Usually added at the beginning of fermentation and possibly again at the mid-point.

Packaging: 25 kg bag and 50 lb. bag.
