Stimulants and Protectants Added to Yeast Rehydration WaterGO-FERM PROTECT® optimizes the micronutrient bioavailability of Go-Ferm with the added benefit of survival factor protection through the NATSTEP® process. These survival factors include specific sterols and polyunsaturated fatty acids that strengthen the yeast membrane during rehydration, making it more resistant to fermentation stress. GO-FERM PROTECT® is used in the yeast rehydration water to create a suspension of micronutrients and survival factors that are bioavailable for selected yeasts. GO-FERM PROTECT® is recommended in place of Go-Ferm® for very difficult fermentation conditions, such as: 1. High maturity conditions (>25° Brix) to protect yeast against osmotic shock, helping avoid high VA production during fermentation. 2. High potential alcohol conditions to protect yeast against alcohol toxicity, helping avoid sluggish fermentation finishes. 3. Over clarified juices to help supply key yeast survival factors.4. Restarting stuck fermentations to protect and condition the “rescue yeast” against high alcohol conditions. Dosage recommendations: Use 30 g/hL (2.4 lb/1000 gal) of GO-FERM PROTECT® to stimulate and protect the rehydrating yeast. Note: This recommendation is based on a yeast inoculum of 25 g/hL (2 lb/1000 gal). If using more or less yeast, respect a ratio of 1 part yeast:1.25 parts GO-FERM PROTECT®. GO-FERM PROTECT® replaces Fortiferm and ENOFERM PROTECT that were previously offered in North America.
