Yeast Nutrient, GoFerm - 1 oz

Product Code:15135OZ

Go-Ferm® is a natural yeast rehydration nutrient con­taining a balance of micronutrients. It was developed to enhance kinetics and thereby potentially avoid problem fermentations. Suspend Go-Ferm in the rehydration wa­ter before adding the selected active dried yeast culture. The yeast soak up the valuable bio-available micronu­trients as they rehydrate. Infusing yeast with these es­sential nutrients arms them against ethanol toxicity and optimizes nutrient availability to the rehydrating yeast culture. The result is fermentations that finish stronger. 

Rehydration with Go-Ferm is effective for helping the yeast survive the fermentation. If these micronutrients were added directly to the must, competitive microor­ganisms would use a significant amount of them and others would be chelated by polyphenols or inactivated by SO2. Do not use nutrients containing ammonia salts, such as DAP, during yeast rehydration - they are toxic to the yeast at high levels.

To Use
Mix Go-Ferm in 20 times its weight in clean 43°C(110°F) water. For every 1 kg (2.2 lb) Go-Ferm, use approximately 5 gallons of water. Let the mixture cool to 40°C(104°F) then add the active dried yeast. Let stand for 20 minutes. Slowly (over 5 minutes) add equal amounts of must (juice) to be fermented to the yeast slurry. Watch the temperature difference. Do not allow more than 10°C(18°F) difference between the must (juice) and the yeast slurry. Atemperate as neces­sary.

Storage
Dated expiration. Store at 18°C(65°F). Once opened, keep tightly sealed and dry.

Recommended Dosage
Use approximately 1.25 g Go-Ferm per 1 g of yeast.

NOTE: This recommendation is based on a yeast inoculum of 2 lb/1000 gal (25 g/hL). If using more or less yeast, respect a ratio of 1 part yeast to 1.25 parts Go-Ferm.

Go-Ferm® is certified organic by OMRI.
