Red Star Premier Cuvée, 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 Cuvée 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. Alcohol tolerance: 14-16%
Wine-fermentation options with different aroma, alcohol tolerance and restart suitability. Check the manufacturer’s protocol for a stuck fermentation or secondary fermentation. Compare attenuation, fermentation temperature, alcohol tolerance and the package pitching guidance before switching; these are recipe alternatives, not a claim that the cultures are identical.
