Reportedly >90% of the world's bourbon comes from Kentucky made in a distillery like this one. It is aged in barrels like this one for 2-4 years or more. There are 9 distilleries and 7 of them are open to the public.
Cost: Free to peruse around the distillery, see the hops grown outside and attached gift shops with bourbon in abundance. A nominal fee is charged for tours.
Verdict: No. Interesting to learn about, but definitely not a must do unless you are a die-hard bourbon lover.
