Strong fermenter for varietal expression in highly clarified musts

LALVIN QA23™ is excellent at revealing varietal aromas (thiols and terpenes). This quality makes it a particularly good yeast for developing varietal Sauvignon blanc passionfruit character and citrus aromas (thiols).

• Aromas of tropical, citrus, and white fruit are commonly used to described QA23 fermented wines
• Produces a large amount of the enzyme β-glucosidase, allowing for the release of bound terpenes responsible for floral and spicy notes
• Low nutrient and oxygen requirements and can ferment juice with low turbidity at low temperatures to dryness
Saccharomyces cerevisiae bayanus strain
• Selected in Portugal by the University of Trásos-Montes and Alto Douro (UTAD) in cooperation with the Viticultural Commission of the Vinho Verde region
