Like the race to make the world's hottest pepper, there's also a heated competition in the culinary world to create the strongest cup of coffee. Right now, the apparent winner is Black Insomnia Coffee, which launched in South Africa last year. With a whopping 702 milligrams of caffeine per 12-ounce serving, Black Insomnia is four times stronger than the average cup of joe. If the idea of trying some makes your eye twitch with excitement, we have some great news: The coffee is now available in the United States.
Previously, the aptly named Death Wish Coffee was believed to be the strongest coffee in the world.But Grub Street reports that they were dethroned after Black Insomnia Coffee hired a lab in Switzerland to conduct an independent study to see which beans were strongest. While Death Wish came in at a powerful 660 milligrams of caffeine per serving, Black Insomnia is the clear winner. (You can see the results in this PDF.)
