Nutrient Vit End™

NUTRIENT VIT END™ is a new specific inactivated yeast, developed by the Lallemand Research and Development group for use in avoiding and/or treating sluggish and stuck fermentations. Low yeast viability is a common problem in alcoholic fermentations, and may be caused by the presence of residual fungicides and/ or short- and medium-chain saturated fatty acids, such as hexanoic, octanoic, decanoic and dodecanoic fatty acids and their esters. The production of these saturated fatty acids by yeast is favored by stressful fermentation conditions, which can arise with low juice turbidity, very high initial sugars, the condition of the selected yeast, or extreme fermentation temperatures during the later phase of fermentation. Saturated fatty acids modify the yeast sugar transport capacity by interfering with the membrane sugar transport proteins. NUTRIENT VIT END™ is a specific inactivated yeast that has very high bio-adsorptive properties for saturated short- and medium-chain fatty acids and fungicides. With these properties, NUTRIENT VIT END™ helps secure the end of alcoholic fermentation. Note: Although NUTRIENT VIT END™ provides a minor supply of yeast nutrients, such as organic nitrogen, it does not replace the regular nutrition program integrating juice parameters and the nutritional needs of yeasts. Preventive dosage: At the very beginning of fermentation, add 30 g/hL of NUTRIENT VIT END™ to juice or must. Curative dosage: With a sluggish or stuck fermentation, add 40 g/hL of NUTRIENT VIT END™ to the wine and let settle then rack off before inoculating with rescue yeast.
