Americans, accustomed to relying on coffee to refresh themselves, now have the opportunity to taste what is claimed to be the strongest coffee in the world. The coffee, called "black insomnia" (Black Insomnia), was launched in South Africa last year. It is reported that the dose of caffeine in this coffee is four times stronger than that of regular coffee; each 12-ounce cup of "black insomnia" has as much as 702 milligrams of caffeine.

Many coffee companies have been fighting for the title of the strongest coffee in the world for years. Not long ago, death wish (Death Wish Coffee) took the lead in this respect. But recent tests in Swiss laboratories have confirmed that "black insomnia" is the coffee with the highest dose of caffeine.

The original leading "death wish" coffee has 660mg per 12-ounce cup of caffeine, 42 milligrams less than "black insomnia" coffee, according to the Caffeine Informer website. The dose of caffeine in both coffees exceeds the dose recommended by the Mayo Medical Center (Mayo Clinic) to drink up to 400mg a day.

Although caffeine dosage is the biggest selling point of "black insomnia" coffee, agents want consumers to remember that its company sells pure coffee. The company stressed that its coffee has no charred or sour taste, but has a walnut flavor and a light sweet taste.

In order to ensure the safety of consumers, black insomnia has reduced the amount of caffeine in the product before sale. The dose of caffeine in "black insomnia" coffee is already on the verge of drugs, the Grub Street website reported. Any coffee company with a conscience should not want to surpass it in caffeine content.
