Features of SY Yeast for White Wine and Sparkling Wine (Saccharomyces Bayanus): 1. Fine quality yeast strains: low demand of additional nutrition; high reproduction ability; quick start of fermentation; 2. Stable, high efficient fermentation even under low temperature conditions or for suboptimal quality raw materials; 3. Good resistance to SO2; 4. Produced wines are full of aroma; 5. Quick flocculation after fermentation, so this beverage yeast can effectively avoid too much wine loss. Applications of SY Yeast for White Wine and Sparkling Wine (Saccharomyces Bayanus): This kind of beverage yeast is suitable for making variety of wines (especially for Italian Riesling, Chardonney, Chenin Blanc, Selillon, Traminer, Sauvignon Blanc, etc.). Our S. cerevisiae is also applicable to secondary fermentation of sparkling wines and restarting stuck fermentations. Brewing Characteristics of SY Yeast for White Wine and Sparkling Wine (Saccharomyces Bayanus): 1. Yeast Fermentation Temperature: 8-30℃; 2. Sugar to Alcohol Conversion: 16.8 (g/L)/ 1% (v/v); 3. Alcohol Resistance: ≥18% (v/v); 4. Glycerol Production: ≥6g/L; 5. Low production of volatile acid;
