Higher aromatic intensity in rosés and whites

This is the latest natural yeast selection from the Institut Coopératif du Vin (ICV). When compared with other yeasts, the Lalvin ICV OPALE® develops more volatile aromatic compounds, resulting in intense and complex fruit aromas in premium white and rosé wines. This yeast also shows good fermentation abilities in the high maturity grapes coming from the Mediterranean and Rhône regions. Wines fermented with ICV OPALE® give the initial impression of volume and softness, followed by a round, intense mid-palate and balanced finish.
