Pours extremely dark with a great foamy mocha head that lasts. Aroma is chocolate, some coconut, I get a hint of maple at the end. Tons of roasted malt, lots of charred barrel, bitter espresso, sharp hop bite, dark chocolate on the finish mixed with more bitter espresso. Also a touch of yeast on the end. Thick and syrupy, full bodied. I expected the barrel treatment to make this one a bit smoother as sweeter. Instead I get a bitter, dry finish. Overall a very dry, bitter BA imperial stout. Not my favorite, but I will finish the bottle.

750mL bottle purchased at Alvarium. Bottle #136/650. Pours a thick black color with over an inch of frothy medium brown head. Lots of lacing. First whiff is bourbon and dark chocolate. Wood, vanilla, earth and dark coffee. The taste is chocolate syrup and bourbon. Some roasted malts, espresso, earth, vanilla and leather as well. Woody, bourbon finish with a bit more espresso. Thick, heavy mouthfeel with a fair amount of carbonation. Noticeable alcohol presence. Outstanding beer.

Outstanding. One of the best Russian Imperial Stouts I have had. This is barrel aged, but the bourbon seems to come through mostly as vanilla, which was nice, because it was only faint, not too strong.

Deep black, rich, full. Delicious.
