Use this yeast nutrient as your "secret weapon" when your yeast starts to lag or you just want to ensure a vigorous ferment! Supplementing with yeast nutrients reduces lag time and give the yeast a boost during sluggish or stuck fermentations.
Wyeast Yeast Nutrient gives your yeast a great start during propagation and provides the nutrients needed to maintain a healthy, active ferment: a blend of vitamins, minerals, inorganic & organic nitrogen, zinc, phosphates, and other trace elements that will benefit yeast growth and complete fermentation.
To use, simply dissolve in warm water and add the solution to your kettle 10-15 minutes before the end of the boil. Use ½ tsp (2.2 grams) per 5 gallons (19 liters) of wort.
Wyeast Yeast Nutrient will remain stable for 1 year if stored in an airtight container in a cool environment.
