## Features

- EFFICIENT FERMENTATION - Craft A Brew’s packaged Fermaid K is a blended complex yeast nutrient that facilitates efficient fermentation by promoting yeast growth and reproduction. Its blend of nutrients helps compensate for nutrient and nitrogen deficiencies in grape wines, fruit wines or beers.
- HOW IT WORKS - This product helps keep yeast in suspension, helps keep volatile acidity levels low and helps absorb fatty acids that are toxic to yeast. Fermaid K contains a blend of inorganic nitrogen (DAP), organic nitrogen (alpha amino nitrogen), inactivated yeast as well as other key nutrients.
- HOW TO USE - Fermaid K nutrient works best if added in 2 doses. The first half of the dose is added 6-12 hours after pitching the yeast, and the other half once the sugar content is depleted by 1/3 of original gravity. Before adding the second dose, mix with room temperature water to avoid excess CO2 release and overflow.
- BREWING RECOMMENDATIONS - We recommend you use 1 gram per gallon of wine. For best results, this product should be used with a yeast rehydration nutrient to assure proper nutrition. The package contains 1 oz of Fermaid K.
- CRAFT A BREW QUALITY - Based in Orlando, FL, our mission at Craft A Brew is to stand as the trusted source for homebrew supplies. Guided by our core values of delivering top-notch ingredients, combining elegance with efficiency in design, and championing environmental sustainability, we ensure that every sip is a delightful experience, savored just the way it should be.
