Scanning through a few supplier websites this evening and I ran across this and it has me wondering...
I've been adding DAP (nutrient) and energizer to my wines right at the beginning (before sprinkling the yeast on top.) But, could that combo be TOXIC to the yeast ? I've never had any problems doing it this way ....DIAMMONIUM PHOSPHATE (DAP) (Nutrient)
DAP usage is 1/2 pounds per 1000 gallons
1.13 grams per 5 gallons
1.13 grams is about a heaping 1/4 teaspoon PER 5 gallons Add at 1/3 sugar depletion as it can be toxic to the yeast if added during the yeast re-hydration stage and the early fermentation stage when the yeast population is low.
