Charrington Brewery was a brewery company founded in Bethnal Green, London in the early 1700s by Robert Westfield. In 1766, John Charrington joined the company, which then traded as Westfield, Moss & Charrington from the Anchor Brewery in Mile End. It merged with United Breweries of London in 1964 to become Charrington United Breweries, then, after acquiring a number of other breweries, it merged with Bass Brewery in 1967 to become the largest UK brewing company, Bass Charrington, later simply Bass plc. The brewing operations of the company were bought by Interbrew (now Anheuser-Busch InBev) in 2000, while the retail side (hotel and pub holdings) were renamed Six Continents.
