Monday mornings are the worst. They are even more terrible if your regular cup of coffee just cannot provide you with enough caffeine. That is why the following five coffee companies exist. With more than double the amount of caffeine of a regular cup of coffee, these coffee blends are sure to save the day.

What makes a strong coffee?
Strong coffee typically refers to one of two things. It can refer to how much flavor the brew has or the amount of caffeine it contains. We are defining the strongest coffee by the amount of caffeine it contains.
Not all coffee is made the same. Certain coffee beans such as Robusta coffee beans contain more caffeine. Robusta coffee beans are not commonly used in specialty coffee blends because they do not contain a wide variety of flavors like their counterpart the Arabica coffee bean does.
While Arabica coffee beans generally have better and more pleasant flavors, Robusta beans contain over twice the amount of caffeine. Because of Robusta coffee’s naturally bitter flavors, they are well suited for dark roasts, Italian roasts, and espresso.
Most of these strong coffee brands do not offer a light roast version of their coffee blends because Robusta coffee beans do not taste great lightly roasted. The coffee brands listed here are specialized in dark roasts, but it is not the roast level that gives their coffee a caffeine kick.
The roast level can only be used to accurately determine the flavor profile, not the caffeine level. A dark roast coffee may indicate that it was made with Robusta beans, which is a good indication that the coffee blend is high in caffeine.
When all else fails, just look at the label. Quality coffee companies will proudly display the type of coffee beans they use on the bag.

#1. Black Insomnia Coffee
Black Insomnia Coffee is a company located in South Africa. They use a blend of both Arabica and Robusta coffee beans to combine caffeine and flavor. Black Insomnia Coffee has been proven by multiple independent labs to contain a minimum of 92 mg of caffeine in each fluid ounce.
This equates to over 736 mg of caffeine for every 8-ounce cup of coffee. And let’s be real, most of us drink more than just 8 ounces of coffee every day. Black Insomnia coffee stands out among the highly caffeinated coffee crowd by emphasizing taste as well as energy in their coffee blends.
Robusta beans can brew delicious and highly caffeinated coffee, but compared to Arabica coffee beans, their flavor is lacking. By blending the two most popular coffee beans, Black Insomnia coffee can produce a highly caffeinated coffee without losing any of its flavors.
#2. Biohazard Coffee
Biohazard Coffee is a single-origin blend with a delicious and unique flavor. This hearty blend has a smooth and “popcorny” taste like Death Wish Coffee. It is less bitter than many of the other highly caffeinated coffee blends on the market.
This clean taste is partly due to the single origin of their Arabica coffee beans. Biohazard Coffee only roasts Arabica coffee beans to maximize the caffeine content of their brews. The Arabica coffee beans are lightly roasted to preserve as much caffeine as possible.
Biohazard coffee contains 77 mg of caffeine per fluid ounce which becomes 616 mg of caffeine in an 8-ounce cup of coffee. This is the second strongest coffee brand on the market today thanks to the heightened caffeination of the Arabica coffee beans and the light roasting process, which preserves the caffeine.
#3. Death Wish Coffee
If you need a wake-up call, look no further than Death Wish Coffee. The company is accurately named because it is the third highest-ranking coffee company when it comes to caffeine content. This is a coffee you have to be careful with.
Death Wish Coffee uses a special blend of Arabica beans to produce one of the most caffeinated coffees on the market. The company boasts that their coffee contains 59 mg per fluid ounce. That equates to almost 500 mg in a standard 8-ounce cup of coffee.
For reference, most 8-ounce cups of coffee contain around 91 mg of coffee. Death Wish Coffee contains five times the amount of caffeine in a normal cup of coffee. And because all that caffeine is being consumed in a shorter amount of time, it gets metabolized faster.
Not only is it five times the amount of caffeine that most people are used to, but all that caffeine hits your bloodstream very quickly. This results in the caffeine having a much greater effect than if it was consumed over the course of a couple of hours.
#4. Killer Coffee Co.
This Australian-based coffee company claims to be the strongest coffee on the continent. Each fluid ounce of Killer Coffee Company’s brew contains 180 mg of caffeine per 100ml. An 8-ounce cup of Killer Coffee has over 425 mg of caffeine.
While this is still an enormous amount of caffeine for an 8-ounce drink, it is a little over half the caffeine content of Black Insomnia Coffee. This is partly because Killer Coffee Company only uses Arabica Beans.
Arabica beans have less than half the natural caffeine content of Robusta beans, but they tend to taste much better. Arabica beans do well with any roast level and nearly any flavor profile. They can provide both delicate and earthy flavors.
Killer Coffee Company provides one of the best coffee blends for people who need to stay awake but hate sacrificing any part of their coffee’s flavor.
#5. Banned Coffee
Banned Coffee prides themselves in making their coffee as healthy as it possibly can be while containing obscene amounts of caffeine. It is full of vitamins, minerals, and antioxidants so you can feel better about drinking three times the amount of caffeine of an energy drink.
Banned Coffee’s strong and smooth taste helps all that caffeine go down easily. It may be delicious but try not to drink too much. Banned Coffee contains almost 40 mg of caffeine per fluid ounce which equals 316 mg per 8 ounces cup of coffee.
This coffee company roasts only the best coffee beans by importing them directly from their country of origin and cutting out the middleman. With both Arabica and Robusta beans creating whole bean blends and coffee pods, Banned Coffee has something for everyone.
Conclusion
Whether you are working a double shift or late into the night, these coffee companies are here to make sure you stay awake. With five caffeine-loaded brands to choose from, you may never sleep again!
