batch B518, 66.7% abv tasted side by side with small batch... the barrel proof is: nose- less nutty, less tannin, less banana more vanilla and sweeter. turns to a nutty/ chocolate bitterness while you sip. palette- strong dried cherry and apricot, salt... first barrel proof in a while... need to remind myself to take smaller sips. lol. add a couple drops of water... brings the bitterness out in the nose and nuttiness similar to the small batch. it's quite nice near halfway between the two, possibly 55%. this brings it near the small batch flavor profile but more intense.
