This is one of my favorite things to do with my out-of-town friends. When I first moved to town, labeling parties were my little secret for awesome get togethers with cool strangers. Now they're a big deal - and still a lot of fun. Put labels on the bottles, and in exchange get some great conversation and a cocktail (or 2). Not a bad deal, and certainly an awesome way to spend an evening.
Wigle products have a broad range - there's bound to be something that will catch your tastebuds (but seriously, don't miss their bitters).
