After almost 150 years of brewing, Marston's has sold its 40% stake in its joint brewing venture with Carlsberg to concentrate on its 1,400 strong pub estate. The Marston brewery at Burton-upon-Trent and the Banks brewery in Wolverhampton now pass fully into Carlsberg's control. Carlsberg Marston's Brewing Company (CMBC) have closed Jennings, Ringwood and Hobgoblin breweries in the last two years, so the future of the two remaining ale breweries may be uncertain following a planned business review by Carlsberg.
