Brains Brewery

Brains (S. A. Brain & Company Ltd.) is a regional brewery based in Cardiff, Wales. It was founded in 1882 by Samuel Arthur Brain. At its peak, the company controlled more than 250 pubs in South Wales (particularly in Cardiff), Mid Wales and the West Country but the brewer sold most of its pub estate in 2022. The company took over Crown Buckley Brewery in Llanelli in 1997 and Hancock's Brewery in 1999. In 2000, Brains moved to the former Hancock's Brewery just south of Cardiff Central railway station. The Old Brewery, in Cardiff city centre, has been developed into a modern bar and restaurant complex.

The company produces a range of beers under the Brains, Buckley's and Hancock's names. As part of their marketing strategy, Brains use shirt sponsorship for the Wales national rugby union team and the Crusaders Rugby League team.
