We used cocoa nibs in a milk stout we did a few months ago.To use a better metaphor, I'd say my chocolate milk experiment falls into the category of R&D, not production. I did it for the sake of learning/trying shit, not to demonstrate a time-effective way of making a glass of chocolate milk.
Dude, buy some cocoa nibs and make a chocolate stout. Then we'll turn an old nissan into a kegerator to serve it up, and give 123 a cranial explosion - OH MY GOD I HATE SO MANY THINGS ABOUT THIS I CAN'T EVEN *bang*
