Red Star Premier Cuvee (Davis 796), a strain of Saccharomyces bayanus from a French wine yeast, is a special isolate of Red Star Yeast & Products. This yeast has good tolerance to ethanol and free sulfur dioxide, and ferments to dryness. Premier Cuvee is noted as a very low producer of foam, urea, and fusel oils. It is recommended for reds, whites and especially champagne. This yeast is reported to perform well restarting stuck fermentations. Winemakers have remarked that Premier Cuvee is the fastest, cleanest, and most neutral fermenter offered by Red Starr. Ferments best between 7-35C (45-95F).
