Hybrid S. cerevisiae & S.bayanus
General Sensory Contribution
Enhances varietal characters and complexity
For unique structural and flavour complexity in dry white winesS6U is a natural hybrid between S. cerevisiae and S. bayanus (formerly S. uvarum). Predominantly used in the production of dry white table wines, chiefly Chardonnay and Semillon, S6U is well recognised for imparting unique organoleptic characteristics - particularly flavour complexity and soft / smooth mouthfeel - that are associated with fermentation and autolytic by-products. Also enhances varietal characters, with an emphasis on floral and spicy notes. Ethyl esters and aromatic alcohols add dimension to barrel fermented Chardonnay. S6U is a slow starter of alcoholic fermentations and has a moderate fermentation vigour.
