I have seen this release at 120.5 proof and 124.3 proof and I've only had the latter of the two. That said, this is perfect. I'm not sure how this release just absolutely few under the radar. There's only 4 reviews here at the time of my review. At roughly the same price point, Knob Creek 15 doesn't hold a candle to this. I'm glad I was able to find a couple more of these with a light coat of dust several months after my first purchase.
