Black Chocolate Stout (USA)
I don't know what black chocolate is, but I probably wouldn't want to eat it. As a drink though, it's wonderful. The aftertaste tastes like you ate a spoonful of cocoa powder, which is pretty bitter stuff. At 10% it's quite a strong beer, and you can taste the alcohol in it. I drank this after a long day at work and it made me feel a bit drunk. It's a winter beer, so won't be available for long periods of the year, but worth a try if you can find it.

Many of the beers I've had from the book so far have been great to try. This, however, is one of the few that could become your "usual" at you local pub. Perfect for drinking slowly on a lazy Sunday afternoon.
