Millions of Americans drink coffee daily. Many can't wake up or get through the day without the caffeine fix they get from it. Following are the Top 10 most-caffeinated coffees you can buy. The names of many of them say it all, and the caffeine counts given are all for a 12-ounce serving, with one exception.
Warning: the source for this puts each of them in its "Dangerous" category for caffeine content. You shouldn't drink this coffee unless you have a high tolerance for caffeine, low sensitivity, or if it's in very small servings.
Black Label Brewed Coffee
This certified organic coffee is most easily found on Amazon. Compare its 1555 mg of caffeine to the 270 mg you'll get on average from the same size of a cup from Starbucks.
Very Strong Coffee
This coffee is made from Robusta beans and has a stronger flavor than Arabica-based coffees. Made by the Great British Trading Company, it has 1350 mg of caffeine.
Devils Brew Extreme Caffeine Coffee
With 1325 mg of coffee, this brew will pick you up. This dark-roasted Robusta coffee tastes good and can keep you up all night if needed.
Taft Coffee
Made in Turkey, this highly caffeinated coffee (1182 mg) blends 50 different beans, keeping it from bitter taste. It's easiest to find in the EU, but you can also get it from the company's website.
High Voltage Coffee
Use 50 g of ground coffee with 12 fluid ounces of water to get this brand's 1150 mg of caffeine per serving. This highly caffeinated coffee vying for the title "World's Strongest" is from Australia.
Black Insomnia Coffee
If you need to keep awake working or driving all night, the name of this one should sound promising. This South African coffee has 1105 mg of caffeine, and it's a blend of 80% Robusta beans and 20% Arabica beans.
Cannonball Coffee Maximum Charge
As the name implies, this coffee will give you a shot: 1101 mg of caffeine. Robusta beans sourced from Rwanda are the basis of this UK-made coffee.
Biohazard Coffee
Like most highly caffeinated coffees, Biohazard Coffee is made from Robusta beans. The extremely high caffeine content (928 mg) makes it unsuitable for pregnant women, children, and people with hypertension or heart conditions. It's lightly roasted for maximum flavor and caffeine retention.
Death Wish Coffee
You can get this highly caffeinated coffee in 5 different varieties. An organic and Fair Trade coffee comes with 728 mg of caffeine when brewed according to the company's instructions. Note that although the website warns of the high caffeine content and the risks it could pose, that warning is not present for Amazon shoppers.
Starbucks Bottled Iced Coffee
This coffee comes in a 48-ounce bottle that has 640 mg of caffeine. That total content puts it where it is on this list, but if you drink it in the same 12-ounce servings as the rest, you'll get 160 mg of caffeine, below the average for Starbucks. After this coffee, the coffees on the list of the most highly caffeinated coffees start dropping sharply toward the average.
