Beans are steamed, so that dissolved caffeine rises to the surface, where it is washed off using an organic solvent called methylene chloride. Caffeine is not the main bitter compound in coffee. Rather, the pungent perpetrators are antioxidants. When it comes to great flavor, coffee chemistry boils down to roasting and brewing. During roasting, oil locked inside the beans begins to emerge at around degrees. The more oil, the stronger the flavor. Caffeine content goes up as the water spends more time in contact with the grounds, so regular coffee often has more of it than espresso or cappuccino.
Darker roasts also yield more caffeine. A millennium ago on a mountainside in Africa, a herd of goats kept a shepherd up at night after feasting on red coffee berries. The shepherd took his animals' discovery to some monks, and very long prayer sessions ensued. It's a good story, anyway.
