The sale includes wine brands Clos du Bois, Geyser Peak, Wild Horse, Buena Vista Carneros and Gar y Farrell, as well as the associated vineyards, winemaking assets and sales organisation.
Fortune Brands initiated the sale after a review and the process resulted in multiple offers for the wine business.
It will now focus on it s spirits and fortified wines, including Harveys sherry and Cockburn's port brands.
Chairman and chief executive Norm Wesley said: "Because the wine industry is lower
margin and more capital intensive than spirits, it's naturally a lower-return segment relative to our spirits business. This sale increases our financial flexibility and will enable us to focus resources on the higher-return premium spirits segment of our business."
A spokesman for Constellation said it was too early for the company to comment on its UK plans for the wine brands. The deal should be complete by the end of December.
