The London Beer Flood was an accident at Meux & Co's Horse Shoe Brewery, London, on 17 October 1814. It took place when one of the 22-foot-tall (6.7 m) wooden vats of fermenting porter burst. The escaping liquid dislodged the valve of another vessel and destroyed several large barrels: between 128,000 and 323,000 imperial gallons of beer were released in total.
