Appearance: Black-brown, opaque. Leather-tan head, nice.
Smell: Coffee, dark chocolate/cocoa—mocha. Rich roasted malt/grain.
Taste: Roasty, stout-bitter but not astringently so. Coffee, chocolate—what you smell is what you taste. Very rich. Earthy dark. Bittersweet.
Mouthfeel: Nice and full. Kind of oily. A little astringent/dry. Smooth.
Yes, my notes are a bit sparse but trust me, this was a well-done chocolate beer. Very rich, very chocolatey; the oily feel in the mouth comes from the real chocolate used in the brewing.
