The Great American Beer Festival (GABF) is a three-day annual event hosted by the Brewers Association held at the end of September or the beginning of October in Denver, Colorado. The GABF brings visitors from around the world to sample more than 1,600 different American beers. Over 100 beer judges from the United States and abroad participate in the evaluations of one or more beer styles, ultimately judging 2,300 beers entered by more than 450 domestic breweries. Gold, silver and bronze medals in 69 beer-style categories are awarded, though not every medal is awarded in each category.
Started in 1982, the GABF was created by Charlie Papazian in Boulder, CO. The original GABF had 22 participating breweries and the 2007 festival had 408.
