A South African coffee billed by its inventor as 鈥渢he world鈥檚 strongest鈥� will soon be available for sale in Canada through the website Amazon.ca.
Black Insomnia Coffee, which already ships to Canada through its website, contains about 702 milligrams of caffeine per 12-oz cup 鈥� more than four times the typical 143 mg of caffeine.
Sean Kristafor, who invented the coffee along with a partner in 2016, told 麻豆影视 Channel Thursday that he believes the coffee tastes great. When people try it, he says, they say 鈥溾�榃ow this is a really good cup of coffee,鈥� and then about 10 seconds later, they say: 鈥榃ow, that鈥檚 actually a very strong cup of coffee.鈥欌��
Kristafor said he drinks a cup when he wakes up at 4 a.m., another about an hour later and then, usually, a third cup later in the day.
Kristafor experimented with a higher caffeine content, but decided that higher levels negatively affected the taste, according to a press release.
Health is also a potential concern. The Mayo Clinic states that up to 400 mg of caffeine per day 鈥渁ppears to be safe for most healthy adults.鈥� Drinking more than that may lead to migraine headaches, insomnia, nervousness, irritability, restlessness, frequent urination, stomach upset, fast heartbeat and muscle tremors, according to The Mayo Clinic.
