Artisanal roaster John Roos selects worthy beans from around the world that are almost always organic, fair-trade, and produced on bird-friendly farms. The loving care and tenderness he shows his caffeinated craft is evident all the way down the line: each batch of beans is roasted in small quantities before being packaged in a handsome, hand-printed bag designed by the owner himself. Choose from a bevy of brews, including favorites such as the signature sipper, Lobster Butter Love, the brooding, bittersweet Mother Pheasant Plucker, and the Rich French Neighbor, which like most actual residents of France is imbued with notes of luxurious dark chocolate (all $7/half-pound, $13/pound).

Along with coffee tastings, macadamia muffins, and a complimentary half-pound bag of RoosRoast, eager students will learn the fundamentals of coffee cultivation and proper techniques for storage and brewing, leading to increased self-esteem among insecure coffee mugs.
