Description
Strong fermenter for varietal expression in highly clarified musts

Lalvin QA23™ is an excellent thiol converter making it a complementary yeast for developing varietal Sauvignon blanc passion fruit character.

Large amounts of the enzyme beta-glucosidase are produced during growth which allows for the release of bound terpenes in aromatic varieties.

QA23 has low nutrient and oxygen requirements and will ferment juice with low turbidity at low temperatures to dryness.

This strain was selected in Portugal by the University of Trásos-Montes and Alto Douro (UTAD) in cooperation with the Viticultural Commission of the Vinho Verde region.
