It's been a while since I've had any Rare Breed, but I remember it being one of the more unique Bourbons I've ever tasted. The regular 101 is pretty unique anyways, eschewing the buttery thickness that I usually associate with bourbon for a cleaner spiciness... Rare Breed does this to near-perfection. The spice and slight floral notes stick out in my memory as being a surprise every time I tasted it. As a man who puts a premium on creativity, I have to give WTRB the highest marks.
(After posting this, I'm going to have to run to the store to grab a bottle!)
