Got in a trade with GreenBayBA. 12 ounce bottle into snifter, bottled on 6/5/2018. Pours opaque dark brown/black color with a small fairly dense and fluffy khaki head with solid retention, that reduces to a a minimal spotty lace cap that lingers. Minimal spotty lacing clings on the glass, with a fair amount of streaming carbonation. Aromas of big milk/dark chocolate, cocoa, caramel, brown sugar, toffee, fudge, marshmallow, vanilla, cream, bourbon, toasted oak, and dark bread; with light notes of coffee, nuttiness, licorice, molasses, raisin, prune, cherry, fig, date, leather, smoke, char, herbal, and yeast/roast/toasted earthiness. Damn nice aromas with great balance and complexity of dark/roast/bready malts, bourbon barrels, and light fruity yeast/earthy hop notes; with great strength. Taste of big milk/dark chocolate, cocoa, caramel, brown sugar, toffee, fudge, marshmallow, vanilla, cream, bourbon, toasted oak, and dark bread; with light notes of coffee, nuttiness, licorice, molasses, raisin, prune, cherry, fig, date, leather, smoke, char, herbal, and yeast/roast/toasted earthiness. Very mild herbal/roast/char bitterness and bourbon/oak tannin spiciness on the finish. Lingering notes of milk/dark chocolate, cocoa, caramel, brown sugar, toffee, fudge, marshmallow, vanilla, cream, bourbon, toasted oak, dark bread; light molasses, licorice, dark fruit, smoke, char, herbal, and yeast/roast/toasted earthiness on the finish for a while. Incredible complexity, robustness, and balance of dark/roast/bready malts, bourbon barrels, and light fruity yeast/earthy hop flavors; with a great roast/hop bitter/sweet, and bourbon/oak spiciness balance; with no cloying/acrid/astringent flavors after the finish. Lightly increasing dryness from lingering hop/char bitterness, and bourbon/oak tannin spiciness. Light-medium carbonation and fairly full body; with a very smooth, creamy/silky/velvety, and slightly slick/sticky/chalky/tannic mouthfeel that is great. Mildly increasing warmth of 13.5%, with minimal barrel booziness lingering after the finish. Overall this is a fantastic barrel aged American imperial stout! All around outstanding complexity, robustness, and balance of dark/roast/bready malts, bourbon barrels, and light fruity yeast/earthy hop flavors; very smooth and dangerously easy to sip on for the huge ABV, with the mildly bitter/tannic/drying finish. Very clean and rich malt complexity, with amazing barrel integration. Not overly boozy/tannic on barrels. Mild fruity yeast and earthy hop balance against sweetness. A highly enjoyable offering, and spot on style example. This was a great experience of developing complexities as it warmed up as expected.
