-
Reduces the risk of browning and premature aging

Outperforms generic inactivated yeasts due to its targeted composition and polysaccharide profile
OptiWHITE is a specific yeast derivative developed by Lallemand through a proprietary production method that preserves functional compounds like glutathione precursors and polysaccharides. Added at the beginning of fermentation, OptiWHITE helps protect varietal aromas and prevents oxidative damage in white and rosé wines. This is especially valuable for wines with thiol or terpene-driven profiles, such as Sauvignon Blanc, Riesling, and Muscat. It contributes to a round, full palate with reduced astringency and bitterness, while preserving brightness and youthful aromas through aging. Compared to standard yeast hulls or inactivated yeast products, OptiWHITE delivers a cleaner fermentation environment with more reliable sensory impact.
Protocol
Add OptiWHITE directly to the juice or must at the beginning of alcoholic fermentation. Disperse in ten times its weight of clean water or must, then mix thoroughly into the tank. Best used before or during the first stages of fermentation. Do not co-add with bentonite or tannins.
