If Denver is the so-called Napa Valley of beer, Falling Rock Tap House is its Opus One—a legend. Though it’s not itself a brewery, beer geeks come from far and wide to sample the constantly changing selection of about 80 drafts and more than 130 bottles—which itself comes from far and wide as well as near, Coloradan and Belgian craft pours, many of them vintage, being the taphouse’s specialties. Shelves lined with 2000-plus beer bottles from the owner’s personal collection make the sprawling, ever-bustling (if not downright raucous) two-story feel like home—as does the cheeky sense of humor reflected in various words to the wise about customer etiquette that appear on the menus.
