For complex whites with citrus and floral notes

Lalvin ICV D47™ is a Côtes du Rhône isolate from Suze-la-Rousse for the production of fullbodied barrel fermented Chardonnay and other white varietals. When left on lees, ripe spicy aromas with tropical and citrus notes are developed. ICV D47™ is a high polysaccharide producer known for its accentuated fruit and great volume. On most white grape varieties, this yeast elaborates wines with ripe stable fruits or jam-like aromas. Thanks to these aromas, the cuvées fermented with the ICV D47™ are a good source of complexity in the blends. Moreover, ICV D47™ contributes to the wine’s silkiness and persistence. Excellent results are obtained for the production of top-of-the-range Chardonnay fermented in barrels, especially when blended with Lalvin ICV D21® fermented Chardonnays.
