Thwaites Brewery is a regional brewery founded in 1807 by Daniel Thwaites in Blackburn, Lancashire, England. The firm still operates from its original town centre site. A variety of cask ales, draught beers, lagers and ciders are produced in Blackburn or imported from Europe by Thwaites. In 1999, the Mitchell brewery in Lancaster closed down, and was bought in part by Thwaites. Lancaster Bomber has since been available from Thwaites public houses after being acquired in the takeover.
