Diammonium phosphate (DAP) is a nutrient that is essential for yeast growth and fermentation. It is a source of nitrogen, which is required by yeast to produce amino acids, proteins, and other essential compounds.


DAP is a particularly important nutrient for winemaking because it can help to improve the quality of the wine. DAP can help to:

  • Improve yeast fermentation activity
  • Reduce the risk of stuck fermentation
  • Produce cleaner flavors and aromas in wine
  • Improve the color and stability of red wines


DAP is a safe and effective nutrient that can be used to improve the quality of any wine. It is a good choice for both new and experienced winemakers.
