Yeast rehydration nutrient; OMRI listed

Go-Ferm Protect Evolution™ is the latest generation of yeast rehydration nutrients. This formulation has optimized the bioavailability of vitamins, minerals and sterols, all of which are derived from inactivated wine yeast. The benefits are clearly seen at the end of alcoholic fermentation.

Yeast rehydrated in Go-Ferm Protect Evolution have enhanced viability, vitality and tolerance to wine stresses such as ethanol, acid, sugar and temperature. These yeast also express more aromatic varietal aromas (Fig. 3) due to Go-Ferm Protect Evolution's high ergosterol content which enables yeast membrane transport systems better aromatic precursor assimilation.

When used in fermentations where oxygen additions are difficult, Go-Ferm Protect Evolution's enhanced sterol content can replace the second oxygen addition recommended at 1/3 sugar depletion.
