I like Makers Mark and Gentleman Jack on occasion but go to 18 year old Glen Fiddich for special occasions. You probably don't want 18 year old anything for an open bar at the wedding, 12-year-old single malts like Talisker, Dalwhinnie and The Macallan should suffice. You really need to taste the varieties as some are smoother than others or will have a smokier flavor.

Some of the larger brands will have small single-shot taster bottles -- that would give you a chance to sample several and pick a few tastes you want people to experience.
