Mostly, it’s just harsh. 15 years is too much for a bourbon. Very woody, in the same way Maker’s Mark special releases are. Now it is pretty complex, and depending on the day sometimes you can tease a great glass out of it—it makes a surprisingly good old fashioned—but it’s always a challenge. Not really worth the money, and it’s certainly no Pappy 15, which is kinda what it wants to be. Maybe give the Barton distillery a few more years and they’ll have some better barrels, but until then… Tl;dr the Calumet 12 is better and cheaper
