Go-Ferm® is certified organic by OMRI. It 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. Using nutrients that contain ammonia salts (such as DAP, Fermaid K, Yeastex 61 or Superfood) dur­ing the rehydration phase can be toxic to the yeast.

Recommended Dosage

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

Usage

  1. 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.
  2. Let the mixture cool to 40°C(104°F) then add the active dried yeast.
  3. Let stand for 20 minutes.
  4. 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 in a cool dry environment at 18°C (65°F). Once opened, keep tightly sealed and dry.
