(750ml bottle from my girlfriend, purchased at the brewery in 2016) Pours black with a small but stable fine tan head and lace. Aroma of slightly sour/acidic dark roasted malt, whiskey, lots of wood, slight smoke, dried berries, umami, char, oxidized twang. Flavour is lightly sweet and somewhat acidic, dark malt with a little raw sugar and chocolate, cherries and red berries, whiskey, vanilla, some metallic/blood notes that give away oxidation. Finish is dry, powdery, a little boozy, vanilla, toasted grain, ash, metal. Medium bodied, creamy soft carbonation. Not sure what happened here; I assumed it was only age making this bottle feel a bit off but reviews here from much further back seem to mention similar characteristics. My girlfriend had it on tap at the brewery in 2016 and enjoyed it a lot but found this barely drinkable, so perhaps bottles suffered some infection as well?

Black color, medium head. Aroma of roasted malt and roasted hazelnuts. Some chocolate flavor, mild sourness, mild acidity.
It may be a bit off because of the sourness, but it’s quite good.

750ml bottle (thx, Chris S.!) shared at Brians office. Pours an almost black with a tan head. Aroma is dark fruits, slightly sour with some bourbon and chocolate notes. Similar taste. Maybe oxidized, but it is still quite good.

Bottle - Dark bourbon roast and a touch if boozy sourness. Jet brown with a light brown head. Light soured bourbon notes with a touch of booze. Thin and not that great.

750mL bottle, pours black with a small light brown head. Aroma reveals subdued notes of bourbon, light coconut, vanilla, and a touch of cocoa. Flavour has light sourness upfront, with gentle bourbon, a touch of vanilla and some dark fruitiness. The tartness probably shouldnt be here. Its solid but slightly off.
