Nectar of the Gods, black gold, cupped lightning, good ol' Joe. Whatever you call it, coffee is the essential life force of the modern world. It's a hot (or iced) mug of energy, of conversation, of social functioning. Without it we would all be half-asleep zombies wandering mindlessly through the streets. And while, at its core, coffee is all created equal, the way you pair it makes it oh-so-unique, and usually reveals a lot about the drinker.
