For complex whites with citrus and floral notes. Suited to wines undergoing barrel fermenation.
LALVIN ICV D47™ is a Côtes du Rhône isolate from Suze-la-Rousse for the production of full-bodied barrel fermented Chardonnay and other white varietals including Muscat. When left on lees, ripe spicy aromas with tropical and citrus notes are developed. . In most of the white grape varieties, this yeast brings ripe fruits and intense aromas. This can be partially attributed to high β-glucosidase activity. It allows for the revelation of good levels of terpenes, including citronellol, nerol and geraniol. Due to release of polysaccharides, this yeast contributes to a round, soft palate with good weight. Moreover, it also contributes to the wine’s silkiness, persistence and complexity. Excellent results are obtained for the production of top-of-the-range Chardonnay fermented in barrels.Fermentation Speed
