In 2014, scientists unveiled the world’s blackest coffee, called Vantablack, that can absorbs 99.965% of visible light.
Now there is a coffee equivalent to Vantablack, the name is Black Insomnia. It debuted in South Africa in 2016 and just arrived in the United States in 2017. No information yet on how much light it can absorbs.
According to its creator, Sean Kristafor, Black Insomnia Coffee packs 702 milligrams of caffeine into just 12 ounces — without adding caffeine to what’s naturally in the beans. And if you thought that Starbucks was strong – you must know that, a 12-ounce dark roast from Starbucks has 195 milligrams of caffeine in comparison.
“the world’s strongest coffee” is a big claim to make — a quick Amazon search revealed three other brands with the same claim — so the company went to great lengths to prove their coffee’s potency.
According to Mayo Clinic , “Up to 400 mg [equivalent to 6 mg/kg body weight in a 65-kg person] of caffeine a day, appears to be safe for most healthy adults. That’s roughly the amount of caffeine in four [6 oz] cups of brewed coffee”. Thus, having just one 6 oz cup of Black Insomnia almost fulfills the recommended maximum intake.
According to Kristafor, during their experimental phase, “any blend that resulted in a higher caffeine content than 702 mg adversely affected the flavor and thus was rejected”.
The certified results from globally renowned and independent SGS laboratories indicate a clear
winner in the title for The World’s Strongest Coffee. With 17524 mg of Caffeine per kg Black Insomnia Coffee is 27% stronger then Wodfee who has 13809mg per kg. Compared to DeathWish Coffee who has only 13179 mg of Caffeine per kg Black Insomnia is a whopping 33% stronger.
