Lallemand GLUTASTAR® | Inactivated Yeast with High Levels of Glutathione

    Description

    GlutaStar – Lallemand Yeast Derivative for Enhanced Glutathione Protection

    • Improves protection against oxidation during aging and storage

    • Delivers high concentrations of reduced glutathione (GSH) for maximum antioxidant effect

    • Enhances tropical and citrus aroma stability, especially in thiol-rich varietals

    • Boosts mouthfeel and roundness without increasing bitterness

    • Outperforms traditional inactivated yeasts with a more targeted composition and higher GSH yield

    GlutaStar is a next-generation specific yeast derivative developed by Lallemand using a proprietary process that yields exceptionally high levels of naturally reduced glutathione. Designed for use in white and rosé wines, especially those with delicate thiol-driven profiles, GlutaStar helps lock in freshness and prevent oxidative damage during maturation, bottling, and shelf life. In addition to preserving bright aromas like grapefruit, passionfruit, and lemon zest, it contributes to a rounder mouthfeel without adding astringency. Compared to conventional inactivated yeasts, GlutaStar delivers superior antioxidant protection and stability, particularly when used early in the winemaking process.

    Usage Rates
    White and rosé wines: 0.2–0.4 grams per liter
    Equivalent to: 0.76–1.5 grams per gallon

    Protocol
    Rehydrate GlutaStar in ten times its weight of water at 30–35°C. Let sit for 10 minutes, then stir thoroughly. Add to must or wine at the beginning of fermentation or at the end of fermentation, depending on the goal. Do not combine directly with bentonite or tannins to preserve efficacy.

    Storage: Dated expiration. Store in a cool and dry environment at 18°C (65°F). Once opened, keep tightly sealed and dry.
