QA-23 is our in-house yeast for all fermentations of Chardonnay, Trebbiano, and Dry Moscato. It is also great for Sauvignon Blanc, though we prefer to use BA-11 in house. We enjoy using QA23 particulary because of how it enhances the mouthfeels of our wines.
Sold in 5g bags designed for fermentations of up to 6 gallons.
QA-23 is known for
- Having low nutrient and oxygen requirements. It has been known to ferment juice at low temperatures (15c) to dryness.
- 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.
- QA23 makes great Cider too!
