Double espressos not doing it for you in the morning? Now you can try Black Insomnia coffee, the self-proclaimed strongest coffee in the world.
Black Insomnia got its start last year in South Africa, and it's finally available here in the U.S., and on Amazon, no less. It contains 702 mg of caffeine in every 12 oz. cup, which is 4 times stronger than the average cup of joe. And no, it's not bitter; in fact, the company boasts its "nice walnut and almost sweet taste profile."
