On October 17, 1814, a 22-foot vat of fermenting porter ale exploded inside London’s Horse Shoe Brewery, unleashing a tidal wave of beer that surged through the impoverished St. Giles neighborhood.

Vault opens the forgotten record on a tragedy that sounds too bizarre to be true—until you see the evidence.
