Barrel #5139, proof 109. Very impressed with this one. I had the straight bourbon and the single barrel bourbon that I liked but found unexciting. This, on the other end is exciting and different. I got a strong aroma of brown sugar and rye spices. The palate is an explosion of spice. Complex yet easy to drink (using a small cube to freshen it up and reduce the proof a little). One great rye. A great value for $56!
