Gabf

The GABF brings visitors from around the world to sample more than 2,000 different American beers. Over 100 beer judges from the United States and abroad evaluate beer in the associated competition, ultimately judging 3,300 beers entered by almost 500 domestic breweries.Gold, silver and bronze medals in 78 beer-style categories are awarded, though not every medal is necessarily awarded in each category.
Started in 1982, the GABF was created by Charlie Papazian in Boulder, Colorado.
