On my recent trip to Denver I hit the Triple Delight: BJ's Brewhouse, the Wynkoop Brewing Company (Denver's first brew pub), and the Coors Brewery Tour.
I have made a small pastime of drinking craft beers and collecting the accompanying pint glasses. If you're ever in Denver, try BJ's Jeremiah Red Irish Ale, it's worth the trip! Zowee! The rest of their current crop of beer, although tasty, tended towards the hoppy end of the scale. Even the nut brown ale was unusually hopped; not something you'd expect.
The Wynkoop Brewing Company had the largest selection of truly tasty craft beers. The only downside is that they had virtually no interesting pint glasses to take home. The logos for the individual beers were all collector-worthy, so this was a true disappointment. Mrs. Nod, whose cupboard is now full, was not so disappointed.
The Wynkoop, located in lower downtown (LoDo) is billed as Denver's first brew pub. The place is enormous -- three stories -- with a a comedy improv club in the basement and billiards on the top floor.
The Coors brewery tour in Golden, CO was both free and fun. I'm not normally a Coors-brand drinker, but I found out that they do make both Killian's Irish Red (a favorite from the past) and Blue Moon Belgian style White Ale (a current favorite). That, and the opportunity to drink beer that has never left the factory was too much to resist. Good cold, cold beer. At the end of the self-guided tour of the brewery you get 3 samples of any kind of beer in their lounge area. Yum.
