I love the Great Gatsby style bottle. The contents - well, $50 for 4 years seems to be a new and irritating entry price for craft bourbon. That said, it beats the pants off of 2 year Peerless bourbon. Trying to pre-benchmark this is still challenging though. For a young bourbon my expectations are not high. The nose is BIG rye and big-ish oak. Caraway, red-hots cinnamon candy, allspice, floral notes, light vanilla, pumpernickel and oak. There is a slight confectioner sugar, and stale bubble gum note that I tend to get from Wild Turkey 101. The initial spice notes make me think of a four roses single barrel. So far there’s nothing not to like. Heavier body than expected but still quite spicy. There is plenty of vanilla, allspice, nutmeg and even a bit of new leather. The oak is really tied to a strangely mineral and sweet element - sort of like floral/clover honey. Honestly it’s a bit funky and the earthy/floral note is hard to place but really unique and interesting (reminds me of Willett 4 year rye but not quite a black tea and mint note). The finish remains rather hot but lengthy and satisfying - those same sweet clover and earthy notes really hang on while the spice fades out. I will say, the closest thing to a flaw is a slightly soapy note between the sip and the finish but it doesn’t stand out and could be related to my hearty consumption of gyros for dinner. I’m pleasantly surprised by this and owe Castle & Key a tip of my glass. I don’t want to hype this - because for stupid, allocated, Kentucky bourbon fever reasons this is apparently already hyped. Regardless, it’s quite good and worth every penny paid. Youth be damned, this is an interesting and slightly daring pour. It’s not one that the faint of palate will enjoy neat due to the spice and sting but the funky undertones are just what this needs to set it apart. This gets a rare 4.0 for south a young bourbon but I’ll stand by it. Just drink it and don’t ogle over the bottle or try to flip it - lest someone club you over the head with it and walk away with their money and your bourbon.
