Got in a BIF from Coronaeus. 500 ml bottle into tulip glass, bottled in 3/2019. Pours opaque dark brown/black color with a 1-2 finger dense and rocky khaki head with fantastic retention, that reduces to a large cap that lasts. Thick foamy lacing clings on the glass, with a fair amount of streaming carbonation. Fantastic appearance. Aromas of big milk/dark chocolate, cocoa, coffee, caramel, vanilla, cream, marshmallow, brown sugar, toffee, bourbon, coconut, toasted oak, roasted nuts, biscuit, and brown bread/crust; with light notes of molasses, dark fruit, smoke, herbal, grass, pepper, and yeast/roast/toast/oak earthiness. Damn nice aromas with great balance and complexity of dark/roast/bready malts, vanilla, bourbon barrels, and light fruity yeast/earthy hop notes; with great strength. Taste of big milk/dark chocolate, cocoa, coffee, caramel, vanilla, cream, marshmallow, brown sugar, toffee, bourbon, coconut, toasted oak, roasted nuts, biscuit, and brown bread/crust; with light notes of molasses, dark fruit, smoke, herbal, grass, pepper, and yeast/roast/toast/oak earthiness. Light herbal, grassy, peppery, roast bitterness; and bourbon/oak tannin spiciness on the finish. Lingering notes of milk/dark chocolate, cocoa, coffee, caramel, vanilla, cream, marshmallow, brown sugar, toffee, bourbon, coconut, toasted oak, roasted nuts, biscuit, brown bread crust, light molasses/smoke, herbal, grass, pepper, and yeast/roast/toast/oak earthiness on the finish for a while. Incredible complexity, robustness, and balance of dark/roast/bready malts, vanilla, 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 flavors after the finish. Lightly increasing dryness from lingering hop/roast bitterness and bourbon/oak spiciness. Medium carbonation and medium-full body; with a very smooth, creamy/silky/velvety/bready, and lightly sticky/chalky/tannic mouthfeel that is fantastic. Minimal warming alcohol for 8.8%, with zero barrel booziness lingering after the finish. Overall this is an incredible barrel aged imperial vanilla porter. All around fantastic complexity, robustness, and balance of dark/roast/bready malts, vanilla, bourbon barrels, and light fruity yeast/earthy hop flavors; dangerously smooth and easy to drink for the big ABV, with the mildly bitter/tannic/drying finish. Fantastic soft feel, not overly bitter/charred. Perfectly balanced super clean/rich malt complexity, vanilla, and bourbon barrel presence/integration; with solid earthy hop balance against sweetness. A highly enjoyable offering, and spot on style example. Very dessert like, but not overly sweet.
