Do you want to get the best out of your dry yeast? Go-Ferm® is a natural yeast rehydration agent containing nutirents which the dry yeast soaks up while it rehydrates. This results in a yeast that once rehydrates, ferments more vigorously and finishes more completely. 

Use 1 teaspoon (approximately 5 grams)  for every 5-6 grams of dried yeast you are rehydrating. Mix Go-Ferm into 4 ounces of hot water for every teaspoon of Go-Ferm. For example, if you are rehydrating a 5 gram pack of dried yeast, use one rounded teaspoon of Go-Ferm and 4 ounces of water. If rehydrating 10 or 11 grams of dried yeast, use 2 teaspoons of Go-Ferm and 8 ounces (1 cup) of hot water. Stir this mixture thoroughly and wait for it to drop to 100 degrees F or less. When under 100 degrees F, sprinkle your dry yeast  on the top of the solution and allow to sit for 15 minutes before pitching.

Here is the manufacturers (quite technical) description of Go-Ferm®

Lallemand’s collaboration with the INRA in Montpellier and other institutes throughout the world have confirmed the critical role of yeast micronutrients, but more importantly, it identified the most effective way to ensure that these micronutrients benefit the selected yeast. The result of this research was the development of Go-Ferm®, a natural yeast nutrient to avoid sluggish and stuck fermentations. Go-Ferm® is specific inactive yeast produced through a unique yeast biomass process fine-tuned to obtain high levels of certain essential vitamins, minerals and amino acids required for healthy yeast fermentations. The Go-Ferm® approach is to provide bioavailable micronutrients in the non-stressful environment of the yeast rehydration water, instead of the traditional method of adding micronutrients to the must. During rehydration, the yeast acts like a sponge, soaking up Go-Ferm®’s bioavailable nutrients. This direct contact between Go-Ferm® and the yeast in the absence of the must matrix avoids the chelation of key minerals by inorganic anions, organic acids, polyphenols and polysaccharides present in the must. It also prevents essential vitamins from being rapidly taken up by the competitive wild microflora or inactivated by SO2. By making key minerals and vitamins available to the selected yeast at the critical beginning of its stressful task, the yeast’s viability increases and fermentations finish stronger. The use of Go-Ferm® results in the significantly better overall health of yeast cells throughout the fermentation, affecting fermentation kinetics and resulting in a cleaner aromatic profile.

Perfect for rehydrating dried yeast

Review by Richard M Perry on 8/1/2018

I bought this product without knowing the first thing about it. I had no idea how to use until I found some pretty clear instructions on Google. I followed the instructions and came up with a very rich looking slurry that I poured into my 7.5 gal FastFerment conical fermenter. After five days my hydrometer told me that my primary fermentation was complete . I removed the collection ball and slowly poured out about 1 1/2 pints of very thick nutrient rich trub. After I wash it I should have about a pint very useable yeast ready for the next five gallon batch. This is a good product which I will use again. One package is good for two batches.
