Chocolate — The addition of bitter baker’s chocolate or bittersweet nonmilk chocolate intrigues a growing number of homebrewers. There you are, brewing a batch of dark beer, and perhaps having a few in the process. And there it is just sitting there in the cupboard, staring you in the face . . . a 1 - 6-ounce chunk of chocolate. “I wonder . . .,” you think, and before you know it, in it goes. Wallah, chocolate beer. And it doesn’t turn out badly, in fact you brew one special batch once a year, to celebrate your impulse.
