Description: Enoferm QA23 was selected in Portugal by the University of Tras os Montes e Alto Douro (UTAD) in cooperation with the Viticultural Commission of the Region Vinhos Verdes. It is used for Chardonnay, Sauvignon blanc, Chenin blanc, Colombard and Semillon for production of fresh, fruity, clean wines. It enhances aromas of terpenic varietals through its beta-glucosidase activity and is an excellent thiol converter making it a complementary yeast for developing varietal Sauvignon blanc passion fruit character. Enoferm QA23 has a low nutrient requirement and will ferment juice with low turbidity at low temperatures (10°C). It is classified as a Saccharomyces cerevisiae bayanus.

I tasted a wine made with this yeast, while the wine was fine, the Stag's Leaf District winery made a switch to the yeast in 2010 and thought it produced terrific wines. In the next breath they complained of more stuck fermentations that previous years. Not proof, but makes one wonder.
