Split bottle purchase with my brother, has been open approximately 1 month Incredible nose of caramel, brown sugar, buttery vanilla, cinnamon, and nutmeg with just the right amount of oak tannins. It is a classic bourbon smell, maybe one of the best examples of what you expect with outstanding bourbons. That smell carries onto the palate. It is rich and dense, really coating the tongue. Bread pudding for days, or apple pie with minimal apple influence. For its proof it is dangerously easy to sip. The ethanol burn on the tongue and finish is akin to something closer to 100 proof. ECBP B520 is really freaking good. This is in my top 5 bourbons of the last few years and is better than the A119. I haven't been a regular purchaser of ECBP releases but I think after this I may be buying every new release. For $60 this is easily one of the best values out there for high proof and longer aged bourbons.
