The Great American Beer Festival comes back to Denver, CO this year after a two year hiatus due to Covid. It's a celebration of all things beer. They receive craft beer from microbreweries from all over the country. Your ticket gets you unlimited samples. With more than 1,500 different beers from 500 breweries, you won't be able to sample all of them and still be alive.
