I sampled a pour of Booker's after a nice steak dinner, delivered in a brandy snifter. Didn't gather any details on the bottling. 100/107-proof bourbons are my favorites, and this Booker's had plenty of fire and I could taste the extra proof, which bothered me mostly in the sense that I felt the fire hid some of the flavor. And the flavor I could taste was nice (and seemed complex), so I wished I could taste more of it. I'm glad I tried it (that pour cost $14), but at $50+ in the store, there are others in that range I buy before Booker's.
