Last weekend, hundreds of brewers from around the country poured their best brews at the nation’s largest beer event, the Great American Beer Festival, in Denver. There were nearly 3,000 different beers pouring on the Colorado Convention Center floor for 50,000 festival-goers. Many of those beers were familiar styles, such as IPAs, stouts, and pilsners, with classic aromas and flavors like citrusy hops and biscuity malt.

Others, though, were truly experimental beers, breaking barriers with wacky ingredients and defying definition. Out of thousands of beers, these five beers were the strangest on the festival floor.
