Lalvin QA23 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 has low nutrient and oxygen require­ments. It has been known to ferment juice at low temperatures (15°C/59°F) to dryness. It is an excellent thiol converter, making it a complementary yeast for developing passion fruit character in Sauvignon Blanc and similar varietals. QA23 produces large amounts of the enzyme beta-gluco­sidase during growth which allows for the release of bound terpenes in aromatic varieties.
