The B520 was my favorite on my shelf of a dozen or so top shelf-ish bourbons. Went to get more whilst on the road since my residence is rather remote. Got this newest small batch instead. Compared them side by side and I definitely like this better. So much complex flavor for 133 proof. There is slight burn but it doesn't overpower the flavor and the next 130+ proof i drink with no burn will be the first. I'll get my greedy hands on every small batch# barrel strength Elijah Craig I can. Absolute steal at $63. Considering going and buying all i can before I head back to the hills.
