Why Yeast-Based Nutrients are Better than DAP: Organic vs. Inorganic Nitrogen Learn why organic yeast nutrition is an important part of wine quality wine production and helps to ensure reliable fermentation.  What's the Difference? Diammonium Phosphate (DAP) Inorganic Nitrogen Inorganic nitrogen is supplied as ammonia (NH3). The most common winemaking source is diammonium phosphate (DAP), which can be found as a standalone nutrient or can be part of a blended nutrient (DAP with inactivated yeast). Yeast-Based Nutrients Organic Nitrogen Organic nitrogen is supplied as amino acids. Common winemaking sources are nutrients derived from autolyzed yeast. These nutrients supply up to 19 different amino acids as well as naturally occuring vitamins and minerals from yeast. Why Choose Yeast-Based Nutrients Although yeast like DAP, it is akin to junk food. Yeast use it quickly and have a metabolic response much like a "sugar rush." Yeast based nutrients are more like a bala
