This strain was isolated from grapes grown in the CÃ´tes-du-RhÃ´ne region of France by Dr. Dominique Delteil, head of the Microbiology Department, Institut coopÃ©ratif 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 15Â° to 20Â°C (59Â° to 68Â°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 rosÃ© wines. An excellent choice for producing mead, however be sure to supplement with yeast nutrients, especially usable nitrogen
