Top 10 Strongest Coffees On The Market

Although some of us prefer a decaf drink every now and then, most can agree that caffeine is the number one reason why we drink our daily cup of coffee.

For many, their day doesn’t truly begin until they’ve had their first cup of coffee and some days it seems like you need a huge boost of caffeine before your brain can even turn on.

With so many options out there for coffee beans and even more ways to brew them, if you prefer a stronger drink, it can be hard to know where to look. Thankfully, some coffees come with a guaranteed higher caffeine content than others, designed to give you what you’ve been missing.

What are the strongest high caffeine coffee options out there?

Some coffee purveyors have aimed to make high caffeine coffees that also taste good, with names like Death Wish, Black Label, and High Voltage being some of the strongest. These coffees are traditionally made with robusta beans which are known for their high caffeine content.

If you’re someone who likes their coffee with a kick, we’ve got a comprehensive list of the high caffeine coffee brands that you have to try. With the addition of one of these coffees to your morning routine and the massive boost of energy you get, you’ll never be able to turn back to your standard espresso again.

#1: Black Label

The Devil Mountain Coffee Company might sound like a terrifying name, but if you’re someone after a strong cup of coffee it probably sounds like music to your ears.

This brand is known for making out-there blends of coffee and their Black Label organic coffee beans is the harshest one yet.

With 1555 milligrams of caffeine for every 12 fluid ounces brewed, it’s a very serious cup of coffee. You shouldn’t even attempt drinking this if you suspect you’re sensitive to caffeine and for those who only have one a day, it’s probably going to be too much for you to handle as well.

#2: Gunpowder Coffee

When taste is more your thing but you need about three cups of regular coffee just to get your going, you’ll love everything about Gunpowder Coffee. 

This brand claims to have the best tasting high caffeine coffee in the world, and judging by their happy customers, they’re not wrong.

Although it’s not in the thousands like some others we’ve reviewed, a 12-ounce cup of Gunpowder Coffee will give you a hit of 644 milligrams of caffeine. The beans are sourced from South America which can take the credit for the delicious taste, but you need to make sure you’re ready for the serious caffeine hit it delivers as well.

#3: Fire Department Coffee

Fire Department Coffee has the lowest caffeine content of our strongest coffee varieties, but that doesn’t mean it’s ideal for everyone. 

This brand was started by a group of US veterans and firefighters who know the importance of getting a good caffeine hit to start your day.

With twice the caffeine of a regular cup of coffee and a huge selection of roasts to choose from, it’s a brand that offers variety. Better still, you’ll feel good knowing that 10% of all proceeds from the sale of their coffee beans go to support first responders in the US.

#4: Death Wish

You might remember the ads for Death Wish coffee during the Superbowl some years ago, and although the caffeine content has been contended since then, it’s still known as one of the strongest.

The US brand only works with fair trade and organic beans which is another bonus if you like to shop ethically.

Each 12 oz cup of Death Wish delivers 728 milligrams of coffee which makes it extremely dangerous. For people who are sensitive to caffeine or those who don’t like a darker and robust cup of coffee, this isn’t one you want to test out.

#5: Very Strong Coffee

As a brand that believes in simplicity and honesty in their marketing, it’s pretty obvious that Very Strong Coffee is going to be high in content. 

This UK bean is made by the British Trading Company and is for people who like only the fullest amount of caffeine in their coffee as possible.

A 12 fluid ounce cup of this coffee will deliver 1350 milligrams of caffeine, and it’s no surprise that the beans used are 100% robusta. Very Strong Coffee delivers on its namesake and will be the only cup of coffee you need that day to keep you going.

#6: High Voltage

Some people who like highly caffeinated coffee also like it to taste serious and bitter as well, but if that’s not you, you’ll want to try High Voltage.

This comes from an Australia coffee brand that claims to have the strongest beans in the country, as well as the best tasting.

A 12 fluid ounce cup of High Voltage coffee will give you 1150 milligrams of caffeine, so it seems on par with the others we’ve reviewed, although not the highest. If you’re happy to give up a little caffeine for a delicious taste though, this is the way to go.

#7: Black Insomnia

If you don’t mind a bit of insomnia yourself and would rather a powerful caffeine hit than a good sleep at night, this could be for you.

Black Insomnia has been around for many years and each time it’s released again, it gets stronger and stronger.

The current caffeine count for this South African coffee is 1105 milligrams per 12 fluid ounces, and it’s got a smoother taste than you might realize. Made up of 80% robusta and 20% arabica, you won’t get an overwhelmingly dark taste from this, but you will get a whole lot of caffeine.

#8: Biohazard

You normally wouldn’t want to drink anything that was called ‘Biohazard’, unless it was your morning coffee, of course.

This coffee will deliver around 928 milligrams of caffeine for every 12 ounces of brewed beverage, and it’s the easiest way to ensure a pick me up in the morning.

Biohazard is made with 100% robusta single-origin beans which means it has a darker taste, but one that many would prefer. Although they claim to be the most caffeinated beans in the world, they come slightly under the winner, but that doesn’t mean they aren’t a force to be reckoned with.

#9: Cannonball

Cannonball coffee comes from the UK brand Maximum Charge, and they claim to have the strongest and most dangerous brew in Britain.

One 12 fluid ounce brew of these beans will give you around 1101 milligrams of caffeine which means it’s not for the faint-hearted.

Cannonball is made with specialty robusta beans that have only been lightly roasted, so while the caffeine content is high, it’s also surprisingly smooth. If you want a good kick but don’t like the bitter aftertaste, this one from the UK might be for you.

#10: Sons of Amazon

The Sons of Amazon brand of coffee is incredibly strong, but still only half the strength of some of the top contenders here.

This would be the ideal coffee for people who like a robust morning beverage but are still somewhat sensitive to caffeine because it manages to meet the middle ground.

Sons of Amazon features around 660 milligrams of caffeine for every 12 fluid ounce of coffee you brew, which makes it incredibly stronger than your standard cup of joe. Better yet, the beans are ethically sourced from the Amazon so there’s no need to feel guilty about drinking this coffee that comes from the popular UK brand.
