Vit End – Lallemand Yeast Nutrient for Securing Fermentation Completion
-
Supports yeast vitality during the final stages of alcoholic fermentation
-
Provides essential vitamins, minerals, and survival factors to avoid sluggish finishes
-
Reduces the risk of stuck fermentation by reactivating stressed or nutrient-starved yeast
-
Enhances sugar-to-ethanol conversion efficiency for cleaner fermentation ends
-
More targeted than general nutrients due to its late-fermentation formulation
Vit End is a specialized nutrient developed by Lallemand for use at the end of alcoholic fermentation, when yeast cells are most vulnerable to nutrient depletion, ethanol toxicity, and osmotic stress. Unlike standard yeast nutrients formulated for the growth phase, Vit End is designed to support cell survival, membrane integrity, and residual sugar metabolism. It contains inactivated yeast rich in survival factors, specific vitamins, minerals, and sterols that help re-energize exhausted yeast populations, allowing them to finish fermentation smoothly. Wines showing signs of slowing kinetics, high residual sugar, or difficult fermentation conditions benefit from the targeted support Vit End provides.
Protocol
Suspend Vit End in ten times its weight of clean must or wine at 20–25°C. Stir thoroughly to dissolve. Add when fermentation is slowing (often near 0–5°Brix) or when signs of yeast stress appear. Mix well to ensure even distribution. Do not add simultaneously with bentonite or sulfites.
Usage Rates
Recommended dosage: 20–40 grams per hectoliter
= 0.2–0.4 grams per liter
= 0.76–1.5 grams per gallon
Use 20 g/hL in moderate stress conditions. Increase to 40 g/hL in fermentations that are near-stuck, have high residual sugar, or show signs of yeast stress. Vit End can also be used proactively in fermentations known to be high-risk due to low YAN, high sugar, or challenging varietals.
