Lallemand UVAFERM 43® Dry Wine Yeast is a professional wine yeast formulated for difficult fermentations where dependable performance is essential. This Saccharomyces cerevisiae bayanus strain efficiently ferments fructose, making it an excellent choice for restarting stuck fermentations, fermenting high-sugar musts, and producing clean, balanced wines with minimal sensory impact.
Designed for both home and professional winemakers, UVAFERM 43® delivers high attenuation, low ester production, and alcohol tolerance up to 16% ABV while maintaining the natural fruit and varietal character of the wine. Its strong fermentation performance and K2 killer factor help support clean, reliable fermentations in challenging conditions.
Suitable for red wines, white wines, rosé, fruit wines, dessert wines, and high °Brix fermentations, this yeast performs across a fermentation temperature range of 59–86°F (15–30°C). Low-to-medium flocculation and a neutral sensory profile make it a versatile option for a wide variety of winemaking styles.
For best results, rehydrate before pitching and pair with proper yeast nutrition and oxygen management. Available in 1.5 g packets for one-gallon batches and 7.5 g packets for five-gallon batches, Lallemand UVAFERM 43® provides consistent fermentation performance from start to finish.
