Product Category: yeast - dry wine yeast
Description: Selected in Portugal by the University of Trás-os-Montes and Alto Douro (UTAD) in cooperation with the Viticultural Commission of the Vinho Verde region, Lalvin QA23™ is an excellent choice for wine styles like Chardonnay, Sauvignon Blanc, Sémillon, Chardonel, and Gewürztraminer. Lalvin QA23™ has low nutrient and oxygen requirements, and it has been known to ferment juice at low temperatures (15 °C/59 °F) to dryness. QA23™ is an excellent thiol converter making it a complementary yeast for developing varietal Sauvignon Blanc passion fruit character. It also produces large amounts of the enzyme beta-glucosidase during growth, which allows for the release of bound terpenes in aromatic varieties.
