The annual Great American Beer Festival (GABF) in Denver is not only about sampling countless beers from U.S. breweries. It’s also the largest commercial beer competition in the world.

GABFglassesAt this year’s GABF, which ran late September, 242 beer experts from 15 countries (including the U.S.) judged 6,647 different beers from 1,552 breweries, representing all 50 states and Washington, D.C. 145 different beer styles within 92 categories were entered into the competition. Certified GABF judges are all experienced judges, and they include brewers, beer journalists, BJCP judges and other industry professionals.

Over three days, judges blindly evaluated beers during five different three-hour sessions (8-12 beers per session). Each table of seven judges was assigned beers to evaluate, and brewers or employees of a brewery are never allowed to judge styles that they enter into the competition.

From the start, the beers are treated with the utmost respect, from making sure they’re transported and refrigerated correctly, to making sure they’re properly poured and presented to the judges in the best possible manner. In turn, the judges treat the job very seriously, and they’re well aware of the immense responsibility.

“My No. 1 job is to create a level playing field,” says GABF competition manager Chris Swersey, “so that the biggest brewery on earth or the smallest brewpub in the tiniest little town are competing on the same field.”

Similar to other national and international beer competitions, beers are evaluated on appearance, aroma, flavor, balance, body and mouthfeel, and overall impression, plus any flaws they may or may not have. Experienced GABF judges say that judging at this level is intense and it requires an immense amount of concentration.

After judges fill out comment cards on their own, they then discuss the beers as a group and, similar to a jury deliberation, decide which beers make the cut to the second and third rounds.

“It’s peer review at its absolute highest standard,” says Swersey. “To put a beer through that panel and come out on top means a lot.”

The ultimate goal of each GABF panel is to identify up to three world-class beers that best represent each beer style category as described and adopted by the GABF. Gold, silver and bronze medals may be awarded, and they are among the most coveted awards in the industry.


GOLD: A world-class beer that accurately exemplifies the specified style, displaying the proper balance of taste, aroma and appearance.

SILVER: An excellent beer that may vary slightly from style parameters while maintaining close adherence to the style and displaying excellent taste, aroma and appearance.

BRONZE: A fine example of the style that may vary slightly from style parameters and/or have minor deviations in taste, aroma or appearance.

If judges believe that no beer in a category meets the quality and style-accuracy criteria, they may elect to not award a medal. In other words, judges may award silver and bronze medals in a category, yet not award a gold medal.

GABFlogoPresented by the Brewers Association, a not-for-profit trade association dedicated to small and independent American brewers and the community of brewing enthusiasts, the GABF is the largest commercial beer competition in the world, and it’s a symbol of brewing excellence.
