White Labs Yeast Nutrient is used to help increase the health of your yeast. Healthy yeast is vital for a clean and complete fermentation, which will also help to prevent off-flavors in your homebrew. Contains diammonium phosphate, essential vitamins and co-factors, nitrogen (amino acids, proteins, and peptides) and minerals. The White Labs Yeast Nutrient provides an effective boost for first and/or late generation yeast slurry. If grist is not 100% malt, then yeast nutrient can help make up for lack of nutrients.
For commercial use, each package contains 1.0 oz, enough for 5bbls. For homebrew use, each 1/2 tsp. from the package is good for 5 gallons.
