They make a big deal out of registered Maker's Mark Ambassadors coming to visit, which was a lot of fun! The tour guide read a proclamation and pinned a medal on me, in front of the whole tour group.
They don't offer tastes of the whisky, but they do give everyone a chocolate bourbon ball at the end of the tour. It's OK; I know what Maker's Mark tastes like! But I really enjoyed the distillery smells, which were mostly the brewing smell that's similar to a beer brewery or a scotch distillery.
