Diammonium Phosphate Yeast Nutrient (DAP)
Boost Fermentation Health with DAP. Diammonium Phosphate (DAP) is a trusted yeast nutrient that provides an essential source of nitrogen for healthy and vigorous fermentation. Perfect for wine, mead, cider, or beer, DAP helps prevent sluggish fermentations and off-flavors by giving yeast the nutrients they need to thrive.
Brewing Notes
- Use Rate: ½ – ¾ gram per gallon
- Purpose: Nitrogen source to promote yeast health
- Form: White crystalline powder
- Package Size: 1 lb (454 g) resealable bag
Why Use Diammonium Phosphate?
- Nitrogen Support: Supplies Free Amino Nitrogen (FAN) for yeast growth.
- Wine & Mead Fermentations: Essential for musts low in natural nutrients.
- Beer Brewing: Helpful in high-adjunct or sugar-heavy fermentations.
- Prevents Stuck Fermentation: Reduces the risk of stalled yeast activity.
Usage Tips
- Dissolve DAP in a small amount of warm water or must before adding.
- For wine/mead, often used in combination with other yeast nutrients for a balanced profile.
- Avoid overuse; excess nitrogen can stress yeast and affect flavor.
Tasting Impact
While DAP itself does not contribute flavors, it enables a cleaner fermentation by keeping yeast active and reducing the risk of sulfur-like off-aromas caused by nutrient deficiencies.
