Fermaid-K Yeast Nutrient

Complex yeast nutrient. Healthy fermentation, fewer off-flavors.

Russ-approvedEditor's choice

≈ $9–$10price range

Yeast need nitrogen, vitamins, and minerals. Fresh juice is often short on all three. Fermaid-K provides them in a balanced complex.

Add at the start of fermentation and again at 1/3 sugar depletion. Don't dump it all at once.
