Whether served in a Manhattan, old-fashioned, mint julep or simply on the rocks — Bourbon has been an American staple since before burgers and baseball. And while whiskey is made all over the world, the distillers in Kentucky have an undeniable reputation for producing some of the best in the game. Big names like Basil Hayden’s and Knob Creek have gained international fame for their Bourbon and now, a few of these industry titans are coming to Denver for a unique event.

Big name brands like Jim Beam, Maker’s Mark, Knob Creek and Basil Hayden’s will be represented this week at the Mile High stop for the “Bourbon Legends Boxcar Tour.”

Described as an interactive party, organizers say the event will feel similar to the Museum of Ice Cream (made famous by its giant pool of sprinkles) … but with booze. It’ll take place on September 12 and 13 and the theme of the event will focus on the oldest mods of transportation for Bourbon, the boxcar. By channeling this classic American form of transportation the creators of the event are aiming to re-ignite a time in the mid-19th century when railroad and boxcars transported Bourbon from Kentucky to the greater United States. Guests will have the opportunity to taste featured Bourbons from each brand and interact with some of the experts behind the booze. In addition to the tastings, the event will feature cocktails, barbecue and music. And to keep an element of secrecy the team behind this unique event will only disclose the location to ticket holders, so an RSVP is necessary — and you can do that here. The best part is the event is free — you just have to be willing to give up your info for some free booze. Once you sign up, you’ll receive an access code and a formal invitation.
