Draught Bass has been brewed under contract in Burton by Marston's Brewery for AB-InBev since 2005. Bottled and keg products are brewed at AB-InBev Samlesbury brewery for export, except in the United States and Belgium, where Bass is brewed locally. The legendary status of Bass is symbolized by its iconic red triangle, recognized as the first registered trademark in the United Kingdom. Bass is the most famous English ale in the world, and has been brewed in Burton, England since 1777. It is a full-flavored ale that is still brewed to an original recipe, using only the finest ingredients and the experience of generations.
