Avery Brewing Co. hosted the 13th annual Boulder Strong Ale Fest on Saturday at the beer maker's new campus in north Boulder, featuring only brews with more than eight percent alcohol by volume. More than 45 breweries, both national and local, tapped 108 different beers for revelers who sampled small pours of brawny beers in the sunny weather. Proceeds from the event went to the National Pancreatic Cancer Foundation. Photographer Danielle Lirette made the trek to Boulder to capture the sudsy fun. See our complete slide show for more photos.
