What Is The World's Strongest Coffee?

What’s the danger of consuming too much caffeine?

If you’ve ever had too much caffeine in the past, you’ll know that it can cause you to experience jitters, anxiety, headaches, and irregular heartbeats.

Still not scared?

Here’s a rundown of the world’s strongest coffee. But brace yourself – the coffees on this list really do pack a punch! 

Who Can Claim To Have World’s Strongest Coffee?

Who Can Claim To Have World’s Strongest Coffee?

When we talk about strong coffee, what we’re really referring to is how much caffeine it contains. That seems to be the selling point of the strongest coffees in the world.

It’s worth bearing in mind that the strength of a cup of coffee doesn’t have anything to do with its roast or how dark the coffee beans that made it look.

It’s a myth to think that a darker coffee roast means that the coffee has a larger amount of caffeine in it as compared to lighter roasts!

To find out more about this, read “Does Roasting Coffee Affect Caffeine Content?” What’s more important than the coffee’s roast is how the coffee is brewed. But, some of the strongest coffees also have other things to offer you than just a kick of caffeine. 

Okay, but if you’re looking for the strongest coffee in the world, you’ll want to get your hands on this one: Black Label by Devil Mountain Coffee Company

One 12-ounce cup of Black Label coffee will give you a whopping 1555mg of caffeine. Yes, you read that right!

That’s pretty scary because it’s been said that you should not exceed 400mg of caffeine per day. This is the equivalent of almost four cups of brewed coffee in one, and it’s why Black Label is thought to be the most dangerous coffee in the world.

How it works is that Black Label is a combination of the strongest whole bean coffees in the world. It’s a dark roast blend that’s rich, savory, and smooth.

You can expect to pay $19.99 for a 16-ounce bag of it.

Amazon reviews have mentioned that Black Label doesn’t taste bitter, thus preventing you from having to use sugar and milk to sweeten it, and that it certainly achieves its job of keeping you awake! Don’t be surprised if you run circles around those around you.

What Other Types Of Strong Coffee Are There?

What Other Types Of Strong Coffee Are There?

There are many other really strong coffees you can reach for if you need something more powerful than your regular cup. Let’s look at them.


This coffee is aptly named because just one 12-ounce cup of it contains 928mg of caffeine. It’s made with Robusta coffee beans and is said to be perfect for when you need to endure a sleepless night, such as when you’re partying up a storm of cramming for an upcoming exam.

Reviews have stated that the coffee does a really good job of keeping people awake and it doesn’t leave you with a strong bitter aftertaste. Instead, it’s said to have a cleaner flavor, which is a bonus.

Death Wish

If its name doesn’t scare you, the coffee certainly will if you’re not used to consuming a lot of caffeine. Death Wish is one of the best brands to provide really strong coffee. You’ll get 728mg of caffeine in a 12-ounce cup of coffee, which is pretty good. 

The coffee beans that are used to make this product are organic and fair trade, so you don’t have to worry about them having a negative impact during their production or worry about the bad chemicals you’re consuming in the coffee, which would certainly be a death wish!

Although you might be expecting a really strong and bitter coffee taste, Death Wish has a strong but pleasant taste. 

You can try it out by buying a 16-ounce pack of Death Wish coffee from Amazon. It costs $19.96.

Killer Coffee

When it comes to choosing really strong coffee, the focus is usually paid to how much caffeine it contains. But there are some brands that are making sure that they also focus on the quality of the coffee beans used to make the product.

Killer Coffee is an example. It is strong coffee that will wake you up in the morning as it contains 645mg of caffeine in every 12-ounce cup. It tastes a lot like regular coffee – it’s a dark roast that provides you with a strong and mellow flavor.

Are Strong Coffees Safe To Consume?

If it makes you a bit worried to exceed the daily maximum amount of caffeine that’s safe to consume, which, as we mentioned earlier, is 400mg, you might think that you should steer clear of the world’s strongest coffee brands. But do you have to?

According to experts (via Today), it really depends on your health and how sensitive you are to the effects of caffeine.

If you usually drink a cup of coffee that contains approximately 150mg of caffeine and you experience negative side effects from it, such as heart palpitations, headaches, insomnia, and others, then it’s probably not a good idea to consume the world’s strongest coffee that could triple that amount (or, multiply it by 10 in the case of Black Label).

It probably makes you jittery just thinking about it, right?

It’s wise to be mindful of any health issues that you have before reaching for a hot cup of caffeine-packed coffee. For example, if you have a heart problem such as heart arrhythmia, the caffeine could worsen your palpitations.

Other health issues that should make you refrain from drinking very strong coffee include anxiety disorders, migraines, and other health conditions that require medicine which has the effect of stimulating the heart, such as ADHD medicines, as Today reports.

And, it should go without saying that staying away from such coffee is a must if you’re pregnant as consuming caffeine has been linked to problems such as an increased risk of miscarriage.  

There are also some important things to bear in mind if you don’t have any health conditions:

  • Before you order a pack of the strongest coffee, make sure you remember that your tolerance to coffee increases the more you consume it. If you start drinking really strong coffee then your body will get used to it. This means that going back to a regular, less-caffeinated cup won’t do the same thing for you and could cause you to become dependent on the caffeine-rich coffee.
  • Caffeine is addictive, and that means you can suffer withdrawal from it that can last for days. Symptoms of withdrawal include headaches, extreme tiredness, lack of focus, anxiety, and irritability.

If you have to stop drinking coffee, such as because you want to consume less caffeine, it’s always a smart idea to do so slowly instead of going cold turkey.

This gives your body a chance to adjust and it can help you to decrease the amount and severity of the withdrawal symptoms.
