The market of the world's strongest coffee in the United States is four times stronger than that of ordinary coffee.

[April 5, 2017] (reporter Chen Juncun reports) just like the competition to produce the hottest chili peppers, people compete to produce the strongest coffee. At present, the title of the world's strongest coffee is won by a product of the same name made by the South African company Black Insomnia, which is more than four times stronger than ordinary coffee and is sure to cause insomnia for many people. Today, the product is on the market in the United States, and consumers can order it through the website.

Black insomnia, which was founded in Cape Town, South Africa, in 2016, offers "black insomnia" coffee with ultra-high caffeine levels. It contains 702 milligrams of caffeine per 12-ounce cup, 42 milligrams more than Death Wish, the world's strongest coffee.

By comparison, the average coffee contains about 150mg of caffeine per 12-ounce cup, less than 1/4 of black insomnia. A can of Coke contains 34 grams of caffeine.

In addition to coffee as a selling point, Black Insomnia also wants consumers to know that this coffee is very pure coffee, which is made from Robusta coffee beans and does not contain any chemicals, sugars, preservatives or other additives.

Although caffeine has the functions of refreshing, diuresis and increasing appetite, the Mayo Clinic (Mayo Clinic) in the United States says the daily intake of caffeine for healthy adults is limited to 400mg. So Black Insomnia advises consumers to drink 6 ounces of their coffee a day so that their caffeine intake does not exceed the limit.

If you have decided to try this super coffee, you can buy it on Amazon, which sells for $19.99 for a bag (16 ounces) of coffee beans.
