Diageo has agreed to acquire a Canadian distillery and bottling plant from Constellation Brands for a sum understood to be in the region of $20m (£10.2m). The purchase of the Schenley plant in Valleyfield, Quebec will give Diageo capacity for the production of its Canadian spirits brands. As part of the deal, which is set to be completed in June following approval by both companies, the distillery’s staff will become Diageo employees. Constellation Brands, the worlds’ largest winemaker, will move its production to its Lethbridge, Alberta plant in Canada. The acquisition is the second this year for Diageo, following its purchase of US winemaker Rosenblum Cellars in January for $105m.
