For the longest time, I thought the coffee flavor determines how strong the coffee is. I’m sure a lot of people think the same way. Well, guess what? It’s totally wrong!

When we feel sluggish, the first thing most of us do is grab a coffee. But for those specific days where you need to stay at your 100%, attention can drift and the mind can wander. The solution is pretty simple. Try a high caffeinated coffee for once. 

In this article, we have tried to put together all the strong coffee brands for when you want a strong kick of caffeine. 

What is the Strongest Coffee?

I used to think the bitter your coffee tastes the stronger it is. Well, it turns out that’s not the case at all. The strength of your coffee is determined by the amount of caffeine it contains. And caffeine is dependent on the type of coffee beans you use. 

So it all comes down to the coffee beans. Most coffee places use Arabica beans which do not have that high amount of caffeine. The serving size is also an important factor to keep in mind. 

Arabica and Robusta are the two most popular types of coffee beans around the world. Robusta, however, has more than double the caffeine content. Most instant coffee uses Robusta beans for that reason. 

So if you are wondering which coffee has the most caffeine, look for Robusta beans. On that note, keep in mind, the roast style does not impact too much on the caffeine level. So whether you go for a dark roast or a light one, it’s all the same. 

What Makes a Cup of Coffee Strong?

Caffeine Content

Caffeine is the primary stimulant in coffee, and the amount of caffeine influences the potency of the coffee. A coffee with a higher caffeine concentration is stronger. A typical cup of coffee has approximately 95 mg of caffeine.

Roast Leve

The roast level of coffee influences its strength as well. A darker roast offers a stronger flavour profile, and the longer the roasting process, the more caffeine there is. Light roasts, on the other hand, are gentler and contain less caffeine.


The origin of the coffee beans might also influence its strength. Different locations produce coffee beans with differing caffeine levels, and certain nations, such as South and Central America, are noted for producing stronger coffee. The soil, climate, and altitude of a place can all have an impact on the growth of the coffee plant and the strength of the coffee it produces.

The Health Consequences of Drinking Strong Coffee

While most people perceive coffee to be healthy, excessive caffeine use can have significant health consequences. The following are some of the negative health effects of drinking strong coffee:

Sleep DisruptionCaffeine, a stimulant, can disrupt sleep and cause insomnia, especially if consumed late in the day.
Heart ProblemsCaffeine can raise heart rate and cause palpitations, which can be dangerous for those with cardiac problems.
DehydrationCaffeine is a diuretic and increases the desire to urinate, leading to dehydration.
Stomach TroubleExcessive coffee consumption can cause stomach issues such as acid reflux, nausea, and diarrhea.
AnxietyCaffeine can make some people anxious, and strong coffee may amplify this effect.

✍️ Note: These health consequences can vary from person to person and depend on individual caffeine tolerance and sensitivity. Consult with a healthcare expert before making changes to your coffee consumption.

The Strongest Coffee Brands

Here are some of the best coffee brands with the strongest caffeine level. Keep reading to find out what is the strongest coffee to buy. We have included amazon links to help you find them easily. 

01. Death Wish:

[amazon box=”B006CQ1ZHI”]

Caffeine Level: 728 mg/mug
Bean type: Secret

Just like the name sounds, it is indeed a Death Wish if you want to try this coffee. Made with a premium blend of Arabica and Robusta beans, this coffee will leave you with a smooth, subtle yet intense flavor. 

Many people claim this to be the strongest coffee in the world. With its 728mg/12 oz caffeine level, you honestly can not argue with them. 

To put things in perspective, according to the U.S. Food and Drug Administration, the safe limit for daily caffeine intake is 400mg. This means one cup of Death Wish is stronger than 5-6 cups of normal coffee!

The beans are sourced from Peru and India, the two best places for high-quality Robusta beans. The brand, however, does not reveal the type of coffee beans they use. Whatever they are using is working is stronger than anything else which is why Death Wish is at the top of our list.

We will talk about Death Wish Coffee shortly again. But before that, let’s explore our other picks!

02. Black Insomnia:

[amazon box=”B06XBY2YRB”]

Caffeine: 702mg/mug
Bean type: Whole bean

Another one that could easily be on the no.1 on our list is Black Insomnia. There are controversies that Black Insomnia has a higher caffeine level than Death Wish. Whether it’s true or not, it’s definitely one of the strongest coffee in the world. 

The first thing that will catch your eyes is the packaging. It’s almost as if the coffee is warning you not to drink it. But for the hardcore coffee enthusiasts, this sounds like a challenge! 

We must say, the taste of Black Insomnia is not anything unique from other premium coffee brands. The main difference is the high caffeine level. 

So you will be awake the whole night without feeling an inch of tiredness. Pretty brutal if you ask us!

We must warn again that no one should consume coffee like Black Insomnia and Death wish every single day. This is probably not very healthy. But when you need that caffeine boost and kick, there is nothing better to go to.

03. Biohazard Coffee:

[amazon box=”B01BO5D218″]

Caffeine: 928 mg 
Bean type: Whole bean

Claimed to have 928 mg caffeine per 16 ounces, Biohazard Coffee can easily be on the top of our list. This one is another brand that claims to be “world’s strongest coffee”. One thing we like about biohazard is that it’s not pre-grounded like most options. 

As it’s a whole bean coffee, you have to grind the beans yourself. There are some great grinders that can do the job in seconds. 

When we want stronger coffee, we add an extra tablespoon of coffee beans. This not only wastes a lot of money, but it also does not make the coffee much caffeinated. Biohazard is efficient in the sense that you don’t need too many coffee grounds to make an energy-boosting beverage.

If you are into fitness a lot, this brand is worth checking out. It’s great for working out and hyperfocusing.

04. Devil Mountain:

[amazon box=”B07C2KSMQD”]

Caffeine: 1555 mg
Bean type: Dark roast. 

For most coffee lovers, aroma and flavor is a big factor in deciding which coffee to go for. Not all of us drink coffee only for the caffeine boost. For those who want both, Devil Mountain is a great option. 

This one is a gourmet coffee that provides a smooth and strong flavor. The great thing is, despite being one of the most caffeinated coffees, it’s not bitter at all. 

Devil Mountain uses premium high-altitude organic beans that have a rich body. So your coffee won’t feel too watery or thin. 

This non-GMO and gluten-free option is known as a cherished find for coffee connoisseurs. Who says strong coffee has to be burnt and bitter?

05. Nuke Coffee:

[amazon box=”B08FY324NT”]

Bean source: Indonesia
Bean type: Arabica and Robusta

If you are picky about where your coffee beans come from, try Nuke Coffee without a hint of doubt. Brought from the heart of Sumatra’s volcanic mountains, this coffee tastes very distinctive. 

The beans are found in Gayo mountain in Indonesia. It’s a high caffeine coffee and perfect for dark roasting.

It has a fruity winy undertone with a deep chocolaty taste. This is due to the red coffee cherries they use to create their blend. Needless to say, it’s absolutely delicious, especially during summertime.

Frequently Asked Questions

If you compare espresso with normal drip coffee, then it’s definitely stronger than that. Espresso has a higher concentration of caffeine, which gives an instant boost to your body. The higher the caffeine level, the stronger the coffee.

The type of coffee bean you use determines how strong your coffee will be. Roasting does not impact the caffeine level very significantly. 

Having said that, we all want to get the most out of our coffee. If your goal is the same then go for a medium roast. Each time you roast your coffee beans, they lose a bit of volume and caffeine. So while darker roasts taste much richer and complex, it does not pack the same level of caffeine. 

03. Which Coffee has the Highest Amount of Caffeine?

Death Wish coffee is surely super intimidating and almost scary to look at. Their packaging does not help to promote a “safe” vibe either. The truth is, Death WIsh coffee is totally safe according to the FDA. but you should not consume more than a cup per day. 

We should not consume more than 400mg of caffeine each day. But Death wish is almost double the amount. So be mindful of how much you use. 

We also don’t think this is something anyone should drink every day. It can be an emergency booster for days when nothing else is working for you. 

05. Why is Death Wish Coffee So Strong?

The brand takes its coffee very seriously, so much so that they don’t reveal anything about its formulation. It’s not clear what type of coffee beans are used in Death Wish coffee.
