Although some people concentrate on coffee’s flavor and aroma, others require beverages with the highest caffeine content. That can only be extracted from certain coffee beans.

These are referred to by some people as the strongest coffee beans. The term strong coffee beans can refer to a type of coffee bean or roast and the amount of caffeine it can produce in a serving/ cup of coffee.


The Amount of Caffeine in the Strongest Coffee Bean

There are 4 well -known varieties of coffee beans. These are Excelsa, Liberica, Arabica, and Robusta.

The most popular and highly consumed coffee beans are the Arabica and Robusta coffee beans.

Arabica coffee beans account for 60 percent of the coffee produced in the world. They are also used to prepare most of the beverages served in cafes. You’ll find that they dominate the shelves in places that sell coffee, such as coffee shop roasteries, groceries, or supermarkets.

Despite their popularity, Arabica coffee beans only contain 85 – 100 mg of caffeine in a serving. That’s about 1.9 mg of caffeine in a coffee bean, which is quite a small amount.

Any caffeine addict who takes a cup of coffee made using Arabica coffee beans will feel like they have not taken enough caffeine. That will force them to take cup after cup of coffee to meet their caffeine needs.

The best type of coffee bean for such people is Robusta coffee. Although these beans contain less flavor than Arabica coffee, they contain about 200 – 265 mg of caffeine in a serving. That translates to 2.9 mg of caffeine per coffee bean.

Some coffee producers blend Robusta coffee with Arabica coffee to combine the flavor of Arabica with the caffeine content of Robusta. These are popular coffee brands like Lavazza coffee, which comprises 60% Arabica coffee and 40% Robusta coffee beans.

Although coffee brewing seems like a straightforward process, you can use certain techniques to get the best-tasting coffee from any type of coffee bean.

It starts with the type of coffee-making machine you use. You need a drip coffee maker or a french press to extract the most flavor and caffeine from coffee beans.

A drip coffee maker will extract a richly flavored and caffeinated brew because you can use it to brew coffee for longer than you would when using a French Press.

While it takes about 6 minutes to brew a strong cup of drip coffee, you only need 5 minutes when using a french press. That extra minute can give you a very potent brew which is why drip coffee makers are used by most caffeine addicts.

You may also use the cold brew coffee making method to get highly – caffeinated coffee from coffee beans. It involves soaking coffee beans for about 24 hours, which gives coffee beans or grounds enough time to release their flavor and caffeine.

Even if you are interested in getting the most caffeine from coffee beans, it’s vital to consider flavor. That makes a burr grinder a must-have product for anyone who appreciates coffee.

You should grind coffee beans right before preparing coffee to get the best aroma and flavor from them. That’s the only way to get the best brew from the strongest coffee beans.
