Please select from the following option(s) to see pricing and availability.

Diammonium Phosphate (DAP). A source of nitrogen for yeast. Use .5 - .75 grams per gallon (1/2 tsp per 5 gallons) of must to aid yeast and help reduce later problems with hydrogen sulfide. There is a superior nutrient regimen (using Go-Ferm and Fermaid K) for wine making:

Will the addition of diammonium phosphate produced geranium smells in wine after doing MLF?

DAP in the right amount is a good thing.
Grapes like children should be fed on a regular basis in order to thrive. But one can do better feeding kids than meet the daily calorie count with chocolates. In the same was grapes can make do on DAP to meet their minimum nutritional requirements, but they will be about as healthy as those chocolate-fed children.

All the wisest advice says dole out DAP in small quantities. Too mush is a bad thing, a little does a lot of good, but only a little.

So follow the wise guys and treat DAP as a light treat for the grapes. Do not over do it.

Good Nutrient
I make a lot of mead and honey has little to no nutrients. I use DAP along with Fermaid K to provide my yeasts with the nutrients they need for a healthy fermentation. This is the difference from those meads that used to take years to ferment and modern mead fermentation the is measured in weeks.
