Strong fermenter for varietal expression in highly clarified white juice

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
Frequently used in: Sauvignon blanc, Chardonnay, Gewürztraminer, Pinot blanc, Albariño, Muscat, aromatic whites, cider
