Theobroma, or, 'food of the gods,' is one of the loveliest beers I've had in quite a while. It's an ale brewed with honey, ancho chilies, annatto, and Askinosie cacao nibs. The recipe is an ancient recreation based on chemical evidence from 3,000 year old pottery sherds in Honduras. An alcoholic chocolate beverage similar to this one was used by early civilizations to toast special occasions.
This is part of Dogfish Head's "Ancient Ale" series-- a collection of unique fermented beverages that have been brewed based off of historic evidence. Some of their other interesting ancient ales include: Chateau Jiahu, Etru Sca, Midas Touch, and Ta Henket.
