I went in August 2014, and while they had a new cask strength blend they were doing, nothing seemed out of the ordinary.
I did get to dip a bottle of that new stuff and still have it. I can’t remember how they explained it to me, that it wasn’t the first run but was still the first batch, or first batch but not the first run or something. Anyway I figured some collector might want it some day, or maybe I’ll just drink it when I find out it’s worthless in 20 years. It’s still decent bourbon!
