Red Star Wine Premier Classic

Red Star® Premier Classic (Davis 522), a strain of Saccharomyces cerevisiae, has been derived from the collection of the University of California. This strain has been widely used in the U.S. since 1963. It is a strong fermenter with good ethanol tolerance, and will readily ferment grape musts and fruit juices to dryness. This strain also has good tolerance to free sulfur dioxide. This strain is recommended for full bodied reds and whites. It is not recommended for grapes that have recently been dusted with sulfur, because of a tendency to produce hydrogen sulfide in the presence of higher concentrations of sulfur compounds. Montrachet is noted for low volatile acidity, good flavor complexity, and intense color.
