Bass is the world's earliest producer of pale ale, whose products were once sold throughout the UK. In 1876, it became the world's largest beer company, with annual production reaching 1 million barrels. In the same year, its famous red triangle logo was registered as the UK's first trademark. The most interesting and unique aspect of Bass Brewery is its brewery museum in a hardened water town. Its beer styles mainly include: pale ale, British stout, strong ale, etc.
