At 928mg Caffeine Per Serving, the World’s Strongest Coffee Is Not for the Faint of Heart

Biohazard Coffee is recognized as the strongest coffee in the world. It has a caffeine content of 928mg per 12-ounce cup, which is more than double the daily recommended dose of caffeine and a lot more than most energy drinks.

The title of ‘world’s strongest coffee’ has been attributed to various brands over the last decade. In 2013, we wrote about Death Wish, a blend that promised 200% the caffeine content of the average dark roast, and then there was Black Insomnia Coffee, a brand that boasted a caffeine content of 702 mg per 12-ounce cup. But now we have another title holder, and this one is going to be tough to beat. Launched in 2016, Biohazard Coffee has established itself as the strongest coffee money can buy, with a caffeine content that makes it barely safe to consume.

The Food and Drug Administration recommends up to 400mg of caffeine per day, for adults with no increased risk factors, like heart disease, also mentioning that rapidly consuming around 1,200mg of caffeine is enough to induce poisoning-like symptoms such as seizures. With a caffeine content of 928mg per 12-ounce cup, Biohazard Coffee is definitely a risky beverage to consume, especially if your body isn’t used to caffeine.

“We wanted a good jolt of energy for our long days without having to sacrifice the taste,” Biohazard co-founder Yonatan Pinhasov said about creating the world’s strongest coffee. “After countless hours of drinking horrible-tasting coffee that promised high energy levels, we decided to take it into our own hands. We thought about all the other people like us – self-starters, parents with long days, grad students, the 18-hour day people…how could we make this better for everyone?”

A warning on the packaging lets consumers know that “at 928mg per 12oz this coffee contains 4x the caffeine of coffee your barista normally serves you,” and that it “may result in overproductivity, all-nighters, and the occasional feeling of invincibility,” but many believe that the playful tone takes away from the real danger of consuming such a strong coffee.

“I feel like the warning should be a little more warning,” one person commented.


“What’s the appeal? I guess I’m just over-sensitive to caffeine, but this would keep me up for days. Just a can of Coke can keep me up all night so this sounds like a nightmare,” someone else wrote.

Biohazard coffee contains more caffeine by volume than most energy drinks, although the latter also contains taurine and other stimulants, but still, 928mg is a lot for a cup of coffee. Just to put things in perspective, a 16-ounce McDonald’s coffee contains about 150mg of caffeine.


Biohazard recommends that “you use our coffee after building up a high tolerance and proceed with caution,” noting that “this coffee is not for the faint-hearted.”
