LALVIN ICV-D47™ Wine Yeast 5 g
For complex Chardonnay
This strain was isolated from grapes grown in the Côtes-du-Rhône region of France by Dr. Dominique Delteil, head of the Microbiology Department, Institut coopératif du vin (ICV), in Montpellier. ICV D-47 strain was selected from 450 isolates collected between 1986 and 1990.
The ICV D-47 is a low-foaming quick fermenter that settles well, forming a compact lees at the end of fermentation. This strain tolerates fermentation temperatures ranging from 15° to 20°C (59° to 68°F) and enhances mouthfeel due to complex carbohydrates. Malolactic fermentation proceeds well in wine made with ICV D-47. Recommended for making wines from white varieties such as Chardonnay and rosé wines. An excellent choice for producing mead, however, be sure to supplement with yeast nutrients, especially usable nitrogen.
