Death Wish coffee may be the strongest coffee in the world. The company's website describes the coffee as a "breakthrough," adding, "Here at Death Wish Coffee we have found a coffee bean with close to 200% the amount of caffeine as your typical coffee shop coffee; we roast it to a medium-dark for a strong and robust flavor and then we grind it to the proper level for extreme potency. We roast to order and inspect before and after the roasting process to ensure correct moisture levels, bean density, and uniformity."
