Yeast energizer is a blend of diammonium phosphate, yeast hulls, magnesium sulphate, and vitamin B complex. Used to stimulate or restart a fermentation.
Add 1/2 teaspoon per gallon of wine must to stimulate or restart a fermentation. Then aerate and apply heat if necessary.
Couple batches of mead made with this and everything is progressing nicely.
I used this as it was recommended for my mead. No problems.
Arrived quickly, but didn't have to use it.
Do you want to be that person who keeps raising populations of unhappy and disadvantaged third world yeast? No, give them nutrients and everything else they need to be as happy as yeast can be, like pigs in a cornfield.
