ACTIVE FREEZE-DRIED WINE YEAST
Successfully ferments highly clarified must
Lalvin QA23 was selected in Portugal by the University of Tras os Montes e Alto Douro (UTAD) in cooperation with the Viticultural Commission of the Region Vinhos Verdes. It is used for Chardonnay, Sauvignon blanc, Chenin blanc, Colombard and Semillon for production of fresh, fruity, clean wines. It enhances aromas of terpenic varietals through its beta-glucosidase activity and is an excellent thiol converter making it a complementary yeast for developing varietal Sauvignon blanc passion fruit character. LalvinQA23 has a low nutrient requirement and will ferment juice with low turbidity at low temperatures (10°C). It is classified as a Saccharomyces cerevisiae bayanus.
