As a recent transplant to the Charlotte, NC area, I finally made my maiden voyage to Asheville this past weekend.
I'll try to sum up into two points.
#1. I've never experienced anything like that in my life. My wife kept saying "this is like Disney for adults". (The frequency and volume of that assertion increased rapidly with each stop we made throughout the day). Never been to Disney, but I had to agree...even if simply for fear of not agreeing w/ my wife at that point. I felt like it was nearly impossible to go more than a couple blocks without stumbling upon another brewery. 50/50 chance I had even heard of it. But nearly every one of them with above average selections.
#2. I've always had a soft spot for Sierra Nevada, but holy **** is their NC facility amazing. Was easily the most memorable part of the weekend for me and we had had amazing experiences at Burial, Green Man, Twin Leaf and Bhramari (both are way under-rated IMO, mostly cause I'd never heard of either), Hi-Wire, etc... so that's saying something. I would consider going back just to spend a weekend there alone.
