About This Event

Castle Rock Beer Fest Under the Stars at the Miller Park amphitheater, Saturday September 12, 4pm to 9pm. Hosted by 105 West Brewing Co. 21+, valid ID required.

Tickets. A Drinker ticket is $90 and a Non-Drinker ticket is $60, both before fees. The ticket is all-inclusive: beer from more than 25 breweries plus a few distilleries and wineries, unlimited servings from 7+ food trucks, and live music. In the organizers' words, leave your wallet at home.

Note: the festival's own website still advertises “over 20 breweries from Colorado and Wyoming” while the ticket page says over 25. All sales are final.
