CY17 Vintners Wine Yeast for Sweet White, Blush and Dessert Wines

Vintner's Harvest Yeast - Cy17
Vintner's Harvest Yeast - CY17 Perfect for sweet white/blush and dessert wines made from grapes and particularly from country fruits & flowers. CY17 produces high levels of desirable congeners during fermentation including aromatic thiols, imparting rich fruity aromatics, full body and �tropical� flavor characteristics. CY17 is also noted for high glycerol formation, further enhancing sweetness. This is a slow fermenter compared to all other strains in the Vintner�s Harvest range, typically taking up to 21 days to ferment table wines and up to 35 days for dessert wines. CY17 prefers a constant temperature in the 22 � 26C (72 -78F) range. Dropping the temperature below 15C (59F) two-thirds of the way through fermentation will arrest fermentation making CY17 suitable for producing naturally sweet wines (both potassium sorbate and metabisulphite must be used to prevent re-fermentation). CY17 is also excellent for sweet sparkling wines, but CL23 must be employed for the bottle fermentation stage. CY17 is a delicate strain that must be treated with some respect - avoid free SO2 levels above 50 ppm and ensure pH above 3.2 . Pay particular attention to sterile winemaking conditions and a warm start to fermentation otherwise risk of bacterial contamination is increased. CY17 will happily ferment up to 15% abv in optimal conditions.
