A balanced blend of proteins, amino acids, and vitamins to improve yeast activity during fermentation. Improves attenuation and the speed of fermentation. Use 1 to 1½ teaspoons per gallon to optimize yeast activity or to restart fermentation. For hard seltzer, which requires more yeast nutrient, use 1 ounce per 5 gallons of sugar wort. Add at the end of the boil after you turn off the heat.
Ingredients: Diammonium phosphate, dipotassium phosphate, magnesium sulfate, and yeast extract.
