World’s Strongest Coffee Beans and Coffee Brands

Are you someone who is always chasing the next caffeine high? If you want to try some coffee with a kick we will list all the strongest coffee and choose a definitive world’s strongest coffee.

So maybe you need a caffeine boost to get you going, here are the coffees with the most caffeine inside the beans. We will be grading the coffee by the most caffeine per 12-ounces of beans.

The World’s Strongest Coffee

This is the best cup of coffee to start your day if you go by the amount of caffeine inside! This is a dark roasted robusta bean with enough caffeine to get you through the WEEK.

By volume, the strongest coffee is Biohazard with 928 mg of caffeine per 12-ounces of coffee beans. That is more than double the recommended daily consumption. If you want to try Biohazard coffee click here.

When we say the strongest coffee we mean the amount of caffeine in the coffee. Depending on how you brew your coffee you may be able to extract more or less caffeine from your beans. Typically robusta beans have almost two times as much caffeine as Arabica beans. The normal Robusta beans contain 2.1% caffeine and Arabica beans contain 1.2%. However, Arabica beans are generally considered higher quality and better tasting. This is because the caffeine is bitter and masks the other flavors of the bean. So, in an Arabica bean, it is less bitter and has a milder, even fruity taste. However, the Robusta bean is better suited for dark roasted coffee drinks and espresso. We generally do not recommend Robusta for a morning blend because it might be too harsh.

Growing the Strongest Coffee

The most caffeine charged beans are grown in specific regions that can most efficiently be grown to contain the most caffeine. Coffee beans are from plants the crop varies each harvest. A coffee grown one year can vary from one year to the next. This is why deathwish coffee and other high caffeine coffee brands test each harvest to find the strongest beans.

Roasting the Strongest Coffee

Caffeine in the coffee bean itself is not dependent on how the coffee is roasted. However, the coffee may taste stronger if the coffee is a dark roast. By roasting the beans you are creating a more bitter flavor that makes it seem like it is stronger because of the flavor. In fact, lightly roasted coffee is actually stronger than dark roasted coffee. This is because the beans are closer to their naturally caffeinated state and the caffeine is not destroyed by the heat of roasting. So, when roasting coffee beans the longer they are roasted the more natural caffeine and the flavor is eliminated.

How to Brew the Strongest Coffee

So when you decide you want to brew a strong cup of coffee you have to choose between whether you want a caffeinated cup of coffee or a flavorful cup of coffee. If you want a cup of coffee that is high in caffeine start with a Robusta bean that is lightly roasted. Choose a brewing method that maximized the amount of time needed to brew. The caffeine content increases the longer you take to brew your coffee. If you want a cup of coffee with the most flavor try a darker roasted coffee or an espresso. You should use Arabica beans if you want a complex cup of coffee with different flavor notes and unique flavors.

Here are three things you have to do to brew a stronger cup of coffee:

  • Increase your Coffee to Water ratio: When you are brewing your daily cup of coffee the most logical thing to do is to add more coffee beans to your coffee to create a stronger cup of coffee. However, if you do this you may get a cup of coffee that is too concentrated.
  • Choose a Dark Roasted Coffee: For a cup of coffee with a strong flavor, but not as much caffeine you should try a dark roasted coffee. The flavor will be “stronger” but it will lack the same amount of punch of caffeine you’d expect. The longer you roast your beans the stronger and richer they will get.
  • Experiment with All Brewing Methods: If you want to make a stronger cup of coffee you can try different brewing methods such as a French press. The water is in direct contact with the coffee grounds in a french press. As a result, the caffeine has more time and surface area that allows caffeine to be infused in the water.

While these tips may make your coffee stronger your resulting coffee may taste too bitter so be careful when using these tips.

The Flavor of Strong Coffee

Like we said before, a stronger tasting cup of coffee does not necessarily have more caffeine. You may think a cup of espresso contains more caffeine than a regular drip coffee, but that may not always be true. Just remember that “strength” is always subjective and just drink coffee that you like whether that is strong in flavor or strong in caffeine.

Grinding a Strong Cup of Coffee

The finer you grind your coffee the most flavor compounds can be extracted by the water. Therefore, if you grind your coffee extremely fine you can have more caffeine in your coffee. This makes it an easy way to control how strong your coffee is. However, the limitation to this method is depending on your brewing method it may leave residue in your coffee. For example, the french press is best used with medium ground coffee because the finely ground coffee will pass through the filter and end up in your coffee.

Our Choices for the World’s Strongest Coffee

Black Insomnia Coffee

This coffee is a brand of coffee from South Africa. So you know it’s the real deal. They advertise the coffee averages 1105 mg of caffeine per 50g of coffee. Black Insomnia Coffee contains 92.08 mg of caffeine per fluid ounce (311.37mg/100 ml).

The blend is 80% Robusta coffee beans and 20% Arabica coffee beans. So, the blend is carefully selected and roasted in an age-old Italian traditional method in a small batch drum roaster. As a result, the blend still tastes good. We compare it to a freshly brewed espresso. First, because it is roasted slowly and carefully it is smooth while keeping a strong aroma. Then, the taste is robust, and there is a velvety body and heady crema if used for espresso. There is no unpleasant bitterness or acidity because it isn’t purely Robusta coffee beans. It is not too bitter and stays flavorful and smooth with a bit of nuttiness and caramel and dark chocolate sweetness.

We recommend this coffee for those who have a high tolerance to caffeine and need something extra for a special day.
