Black Insomnia could be the world's strongest coffee

Be wary out there if someone hands you a cup of coffee and says, "Be careful, it's strong".

Black Insomnia sought to shake up the coffee industry by offering coffee lovers a coffee that was way stronger and darker than they were used to drinking.

Through independent lab tests at SGS, a company specializing in the verification of company claims, Black Insomnia found that its coffee has 6.35 percent more caffeine than Death Wish Coffee, the former title-holder for the world's strongest coffee.

If you're daring enough to give it a shot (pun intended), apparently Black Insomnia isn't all about caffeine. One 12-ounce cup claims to have three times as much caffeine as a regular cup of Starbucks joe, which may be the answer to kicking our 3-a-day grande latte habit to the curb. Large amounts of caffeine-like 20 normal cups' worth-can render over-the-counter painkillers toxic.

Now, Black Insomnia sells five to six tons of coffee monthly. This is not to say that coffee, either chemically enhanced or natural, couldn't be stronger but rather that it shouldn't.

Sean Kristafor, who invented the coffee along with a partner in 2016, told CTV News Channel Thursday that he believes the coffee tastes great. This all depends on how you brew the coffee, of course. "The most serious effect would be an irregular heartbeat". The same size for Death Wish Coffee contains 330 mg.

The "world's strongest coffee" is so strong, it will drive you over the daily caffeine limit and give you heart palpitations. Both types of coffees is available for sale on Amazon, which could not be reached for comment.
