Strange topic but Branston was one of Crosse and Blackwell's brands started in the 1920's.
Nestlé bought Crosse and Blackwell in the 1960's, then Premier Foods (Mr Kipling, Ambrosia, Sharwood's, Oxo, Bisto, Batchelors etc.) bought the Branston brand in 2004 and launched Branston Beans in 2005. A Japanese company Mizkan now own the Branston brand.
Fantastic baked beans Branston Beans, much better than those Heinz beans from Wigan that are mostly juice.
