Not an alcoholic drinker, but saw the sign driving from Nashville and Chattanooga, and decided to take a detour and visit the distillery.
The visitor center is nice and modern, with exhibits all around the large room. The tour is free.
The tour starts with a group photo, and then a short bus ride. You're given the history of the company, and then walked through several buildings, from the original office, to the water source, and one of the warehouses. We were told that the tour would take an hour, and it ran about 15 minutes extra.
Because of local laws, they don't sell liquor that they make there (other than some promotional bottles). There are also no free tasting, but the free lemonade was quite good.
