Carlsberg Marston's Brewing Company is the British subsidiary of Carlsberg Group, operating multiple breweries. It was founded by a merger of Carlsberg's existing UK operations and Marston's plc brewing operations, the latter of which had a 40% share in the business from the entity's founding in 2020 until July 2024.
The main beers are Mansfield, Wainwright, Marston's Pedigree and EPA, McEwans Export, McEwan's Special, Bombardier, Wychwood Hobgoblin, Jennings Cumberland Ale, and Banks's Bitter and Mild. Despite a general UK-wide decline in the popularity of mild ales, Banks's Mild still outsells its stablemate bitter in the West Midlands market and is the best-selling mild ale in the world.
Marston's share price is listed in London under the ticker MARS.
