Medium or dark roast coffee beans, freshly ground up and brewed in a French press. Black with no cream or sugar ever. Every once in a while I might add a splash of milk to a cup to shake things up. Keep instant coffee the hell away from me unless we're traveling or camping.
I used to enjoy the typical Mr. Coffee drip machine style until I had roommates who had French presses. Man, it's SO much better from a French press.
