There are dozens of brands that claim to make the world’s strongest coffee, but there can be only one highest caffeine coffee in the world. It took a lot of searching, reading more than a few lab tests along the way, but here it is: The list of the most caffeinated coffees you can buy online today.
Grab your mug and ready yourself, because there’s enough octane in these results to power an army of coffee guzzlers and a battalion of espresso drinkers. Or you could just keep it all for your own consumption, I guess.
Quick Answer: Highest Caffeine Coffees
- Highest caffeine coffee: Devil Mountain Coffee Black Label — 1035 mg per cup
- Black Insomnia Coffee — 1035 mg per cup
- Highest-caffeine single-origin coffee: Cannonball Coffee Maximum Charge — 1035 mg per cup
- Biohazard Coffee — 1035 mg per cup
- Player One Coffee Insomniac — 1035 mg per cup
- Best high-caffeine coffee: Death Wish Coffee — 1035 mg per cup
How Much Caffeine Is in Coffee?
A typical cup of coffee has about 95 mg of caffeine, but the actual caffeine content can vary significantly depending on the roast level, the brewing method used, the type of coffee bean, and the coffee-to-water ratio used in the brewing process.
How much caffeine is in espresso?
There’s a common misconception that espresso-based coffee beverages have more caffeine than the types of coffee drinks made with regular drip coffee. A 1-ounce shot of espresso has about 65 mg of caffeine. Ounce-for-ounce, that’s more caffeine than drip coffee, but drinks like lattes and cappuccinos tend to be diluted with enough water, milk, and other ingredients that they have less caffeine overall than drip coffee.
Of course, that’s assuming that you are diluting the espresso with something non-caffeinated. Some of the most caffeinated coffee drinks involve diluting espresso with coffee. If you want to up your caffeine intake without resorting to high-caffeine coffee beans, you should give red-eye coffee and its variants a try.
Caffeine Content: Arabica vs Robusta
Not all coffee beans are created equal. Most coffee drinkers prefer Arabica coffee beans because they exhibit sweet, fruity flavors that can be quite complex. Robusta beans, on the other hand, are frequently used only used in espresso blends, instant coffee, and cheap coffee blends. They cost less to produce than Arabica and contribute to a richer crema (the layer of foam on top of espresso), but they taste much more bitter than Arabica.
For caffeine junkies, there is a big reason to consider introducing more Robusta into your coffee mix: They often contain 2-3 times as much caffeine as Arabica. That’s why you’ll see so many of them featured in these high-caffeine coffee blends. It’s also a good reason to check out Vietnamese coffee brands, as Vietnam grows 40 percent of the world’s Robusta beans.
How Much Caffeine Is Too Much?
The US Food and Drug Administration (FDA) recommends no more than 400 mg of caffeine per day for an adult. That’s about four cups of standard coffee of six shots of espresso.
Keep that number in mind as we look at some of these high-caffeine coffees. Some people are less sensitive to caffeine than others, but unless your caffeine sensitivity is very low you should be careful trying the highest caffeine coffee beans on this list.
Highest Caffeine Coffees
Highest caffeine coffee: Devil Mountain Coffee Black Label
Caffeine per 8-ounce cup: 1035 mg
- Black Label is an amalgamation of the world’s strongest and organic whole bean coffee. Hence, One cup of this coffee will make you unstoppable throughout the whole day.
- Black label serves you with a unique dark roast blend that is smooth, full-bodied, rich, savory and sinful.
- It adds flavor to your life and excludes bitterness so that you can enjoy the great taste without jitters.
- Devil mountain coffee’s Black label is certified by USDA organic.
- If you are mad for high-powered coffee then you’ll like Black Label because it incorporates more than twice as much as caffeine then a regular coffee.
With about 10 times as much caffeine as a typical cup of coffee, Devil Mountain is just a ridiculously concentrated source of caffeine. Just one cup provides over twice as much caffeine as the recommended daily maximum. Unless you have an incredibly high tolerance to caffeine, I’d suggest something further down on the list.
With the warnings out of the way, here’s the upside of this dark roast. Black Label uses USDA-certified organic beans that are high-altitude grown for quality. The high caffeine content is coupled with a rich aroma, heavy body, and a strong flavor that is smooth and not bitter.
Black Label is also available as a medium-ground coffee, a coarse ground coffee for cold brew, and the strongest k-cup coffee you can buy. I do recommend the whole bean, though. Ground coffee will never deliver the freshness that you get by grinding your own coffee beans.
