Is there a distillery tour in your area that's not to be missed? What about a brewery tour that is so good you have all of your out-of-town visitors try it out? Brewery tours are a great way to score free drinks (at some locations, as long as you are of age!) while learning about the company's history and business practices. You can decide if it's really the kind of beer (or other spirits) you want to support while expanding your experiences and sampling new drinks. Honestly it's one of the best dates you could plan for drinker friends or dates.
The Anheuser-Busch Brewery in St. Louis does a wonderful tour where you can really get a behind-the-scenes look, multiple drinks and snacks in the hospitality room, see the Clydesdales and much more. It's a lot of fun, and if you want to enjoy even more than what you get on the free tour there are tours for a fee with even more experiences, like beer school and tours with more drinking options, like a sourvenir glass.
