Black colour, small head. The aroma is mild, some roast. Good body strength; very roasty, with strong bitterness, also some vegetable bitterness, this could be from the cocoa nibs, a bit earthy.
Unbalanced.

355ml can from the brewery that pours a real dark brown colour, kind of black with no visible highlights. Beautiful big creamy, bubbly head that is light mocha-coloured, creating a cascade effect, with great retention and full foamy lacing patches. Bitter chocolate nose with some coffee, cereals, alcohol and roasted malt base. Flavours are quite rich and strong. Chocolate from sweet to bitter, coffee and the hops that add to this bitterness with some grassiness. A very dry finish that lingers. Silky smooth mouthfeel. Probably hard to have another one of these right after, but great as a starter.

12oz (thx, Phill S.!) @ home shared with Alex and Ash. Appearance: almost black with a tan head. Aroma: roasted malts, some fruity notes, a bit inky. Taste: along the same lines with lots of chocolate, and vanilla, but also with noticable bitterness. Overall: good stuff.
