Go-Ferm Protect Evolution® is a natural yeast rehydration nutrient developed specifically for problem musts and stuck fermentations. It is certified organic by OMRI. Difficult fermentation conditions may include overripe fruit (>28°B), marginal fruit quality (poorly developed fruit, Botrytis, rot, high bacteria count, insecticide or fungicide residue), low nutrient levels and overclarified juice.
Go-Ferm Protect is the result of a multi-year study of problem fermentations by Lallemand and National Agricultural Research Institute (INRA) in France. Their scientists found that in problem musts deficiencies in sterols and polyunsaturated fatty acids can leave yeast susceptible to osmotic shock, ethanol toxicity, temperature and other stress factors. The NATSTEPTM (NATural STErol Protection) process was designed to meet these fermentation challenges.
Go-Ferm Protect incorporates sterols and polyunsaturated fatty acids (for cell protection) together with vitamins and minerals to help ensure yeast survival and to help maintain fermentation activity to completion. Go-Ferm Protect provides a combination of protective and nutritive benefits for optimal fermentation results.
