Lallemand PURE-LEES LONGEVITY™ | Mannoprotein | Oxidative Protection | Mouthfeel

    Description

    Pure Lees Longevity – Lallemand Yeast Derivative for Oxidation Protection and Wine Stability

    • Protects against oxidative spoilage during aging and storage

    • Preserves freshness and aroma by reducing dissolved oxygen

    • Enhances mouthfeel while contributing to wine structure and roundness

    • Mimics the benefits of lees aging without risk of reductive faults

    • Superior to standard inactivated yeast due to HPH™ processing and high antioxidant activity

    Pure Lees Longevity is a specialized inactivated yeast derivative developed using Lallemand’s High Pressure Homogenization (HPH™) process, designed to provide both antioxidant protection and mouthfeel enhancement in wines. It is rich in compounds with high oxygen-binding capacity, including peptides and polysaccharides, which actively scavenge oxygen and inhibit oxidative reactions. When added to wine after alcoholic fermentation or prior to bottling, it slows oxidative aging, helps maintain varietal expression, and contributes to a rounder, fuller palate. Compared to conventional inactivated yeasts or lees aging, Pure Lees Longevity provides more targeted protection without introducing off-aromas, making it ideal for wines requiring shelf-life extension or longer aging potential.

    Protocol
    Suspend Pure Lees Longevity in ten times its weight of clean wine or water at 15–25 °C. Stir gently until fully dispersed. Add at the end of alcoholic fermentation, during aging, or just before bottling. Mix thoroughly. Allow a minimum of 2 days of contact before racking; contact may be extended to enhance results.

    Usage Rates
    Recommended dosage: 20–40 grams per hectoliter
    = 0.2–0.4 grams per liter
    = 0.76–1.5 grams per gallon

    A typical rate of 30 g/hL (0.3 g/L or 1.14 g/gal) offers effective oxidative protection and subtle mouthfeel enhancement across a broad range of white, rosé, and red wines.
