Death Wish Coffee, An 'Extreme' Coffee With 200% More Caffeine
http://tinyurl.com/bmzrrge "Forget about Jolt Cola - Death Wish Coffee, dubbed "the world's strongest coffee," claims to have 200% more caffeine than "your typical coffee shop coffee." Death Wish is an organic, fair trade, medium-dark roast, and is sold in both ground and whole bean varieties."
Of course you could make it with some caffeinated water for even more kick...
