Lalvin CY3079® was selected by the BIVB with the objective of finding a yeast that would complement typical white Burgundy styles. CY3079® is a steady, average fermenter, especially at cold temperatures (13°C). Its fermentation finish is slow due to early autolysis resulting in roundness. This yeast greatly benefits from using rehydration nutrients and complex yeast nutrients designed for use during fermentation. When properly fed, CY3079® has good alcohol tolerance (up to 15%) and is a low producer of VA and sulfides. It is recommended for barrel-fermented Chardonnay and sur lie ageing. Chardonnays produced with CY3079® have rich, full mouthfeel and are characterized by aromas of fresh butter, almond, honey, white flowers and pineapple.
