My husband and I (along with a pair of friends) took the Saturday tour with Cliff in November and it was beyond compare. Cliff is THE man about all things beer - and has the certification to prove it - and our time on the tour was so educational - - seriously! While I enjoy beer a lot, I came into the tour with minimal knowledge about varieties, the process, etc. Cut to 3 hours later, and I feel like I have such a good grasp on the basics, which is exactly what I was looking for (however, if you already know a fair amount about beer, you will definitely still be able to learn more -- you can get as much education as you want out of this tour). Cliff definitely takes the time to answer all of your questions and was funny and personable, to boot. Additionally, he imparts you with some interesting tid-bits about the history of Asheville throughout your tour, which we really enjoyed as well. Last, the breweries we visited were fantastic and each had their own unique personality, which is a wonderful reflection of the thought and energy that Cliff puts into his tours.
I cannot say enough good things about this tour and absolutely recommend that you experience it for yourself!
