Buyers Guide: Choosing The Very Strong Coffee In The World

Of all the brands we reviewed, we will never know for sure which one makes the strongest coffee.

We all have various preferences for coffee and how much caffeine we want in our cups. With that said, we have curated a list of specifications that you would like to look out for. To help narrow down your list of the strongest coffee brands.

Amount of Caffeine

This is the most obvious and the first thing you want to check. When choosing coffee with more caffeine than your average cup. Most brands will provide you with the specific amount of caffeine it contains.


Keep in mind that you have to choose what your body can handle. We suggest that you gradually increase the amount of caffeine you consume. If you are still transitioning. You can start with brands like Banned Coffee which only has over 400mg of caffeine.

If you can’t handle caffeine, we have the best decaf coffee beans for you.

Coffee Bean Type

If you have noticed. Most of the brands we reviewed, such as Death Wish Coffee, are made with a blend of both Arabica and Robusta. If you are familiar with the two main types of beans. You will know that Arabica has less caffeine concentration but provides more flavors.

Cup of Coffee with whole bean

We recommend going for a brand made with a pure Arabica bean for the newbies. This will lessen the bitterness and give you exciting flavors. This way, it can also help you slowly increase your caffeine.

What Is Strong Coffee?

Several factors play a role in the strength of a coffee. Such as different coffee extraction methods and grinding size. Typically, a light roast coffee contains the most caffeine than a medium roast and dark roast. But you will see that almost all of the brands we mentioned are dark roasts.

The most common method that baristas use to give more caffeine. Is through adding more espresso shots than milk. This is because most of them are made with blends of the two coffee bean types.

For this reason, companies have researched and produced coffee with higher caffeine content.

Strong coffees are your healthiest option to get more caffeine. Without running the risk of drinking too much coffee. After long months of research and experimenting with different bean types and roasting methods, they aim to provide you with the perfect caffeine concentration.

Benefits of Drinking Strong Coffee

Coffee is a popular beverage that we love to include in our daily routines. Some people drink for the flavor, while others use it as an energy booster to jump-start their day. This is because coffee is an excellent source of natural caffeine.

Other beverages contain caffeine, like soda. But despite soda tasting way better and more refreshing than coffee, it is not a healthy choice. Drinking coffee can give the human body several health benefits. Which you will find in our list below.

Regular Dark Roast


Coffee is rich in antioxidants because that provides mental health improvements and boosts thinking skills. This is also why some beauty products contain coffee in their ingredients.

The caffeine content that is found in coffee aids in reducing puffiness and bloating. Keep in mind that extensive research is still needed. To confirm how much caffeine is healthy for the human body and mind.

Effects on Colon and Liver

There is speculation that high caffeine may help improve severe disease progression such as hepatitis C. Research suggest that caffeine can aid bile secretion from the colon wall. [1]

This is because the cafestol palmitate in coffee enhances the activity of an enzyme that stimulates bile secretion, also known as glutathione S-transferase. (Bora, et. al., 2014)

Weight Loss

If you are looking for a healthy way to burn fats, coffee is proven to aid in this problem. This is because drinking coffee helps suppress your appetite for a temporary period. This also results in the loss of the desire to eat.

There is not enough research on this, but scientists believe that when certain compounds in our body are stimulated by caffeine consumption, it can generate heat that may help reduce fats.


Caffeine contains mental-energizing properties that do improve not only concentration and focus but also overall fatigue. This explains why you get a burst of energy after consuming caffeinated beverages.

The Verdict

We all love the rush we get from caffeine, especially in the morning. This is why coffee is well-loved because it is an enjoyable beverage also a source of energy.

But because we love it so much, we sometimes develop a tolerance for caffeine. This is why strong coffee was produced. Black Label is the strongest coffee option for us. Due to the fact that it has enough caffeine for those who enjoy a good rush. Additionally, it tastes so good that you will not notice how strong it is.
