  • Excellent thiol converter making it a complementary yeast for developing varietal Sauvignon Blanc passion fruit character.
  • Produces large amounts of the enzyme beta-glucosidase during growth which allows for the release of bound terpenes in aromatic varieties.
  • Lalvin QA23 is particularly recommended for Chardonnay and Sauvignon Blanc wines with a tropical (thiol) profile.
