Description 

 

Selected in Portugal by the University of Trás-os-Montes and Alto Douro (UTAD) in cooperation with the Viticultural Commission of the Vinho Verde region, Lalvin QA23™ is an excellent choice for wine styles like Chardonnay, Sauvignon Blanc, Sémillon, Chardonel, and Gewürztraminer.

Lalvin QA23™ has low nutrient and oxygen requirements, and it has been known to ferment juice at low temperatures (59 °F) to dryness. QA23 is an excellent thiol converter making it a complementary yeast for developing varietal Sauvignon Blanc passion fruit character. It also produces large amounts of the enzyme beta-glucosidase during growth, which allows for the release of bound terpenes in aromatic varieties. What all this means is this yeast is a good choice for white wine, particularly if your ferment will run to the cool side. 5 gram pack for 5 gallons of must.

Good cider yeast, if you have good juice
Cider is basically a white wine, so this yeast is a good choice.  In my trials it produced a very dry, crisp cider with some apple character, quite a lot like a dry Sauvignon.  If your fruit lacks character and tannin, this is probably not the best choice (try D47 or 71B instead).  If you have some wild apple-crabs or true cider apples, this yeast produces interesting and very drinkable ciders.
