I heard about Doc Porters about a year ago and recently saw a Groupon for a tour so I quickly bought it and made a reservation for 3. The tour lasted about 45 minutes and was held in one room. The tour guide was very knowledgeable and answered everyone's questions. I am all for supporting small businesses so at the end of the tour I had the opportunity to buy a first barrel bottle of their bourbon. I was very excited about that! I'd recommend this tour to others as it's a great thing to do on a rainy afternoon, which is when I did it!
