Does Strong Coffee Have More Caffeine

Strong coffee will change your drinking experience. Some people even report that this beverage can wake them up. Hence, the rest may associate coffee strength with its caffeine content.

So, does strong coffee have more caffeine? And what affects the caffeine level in java? If you can’t answer those questions, we will get you covered.

This article will explain the link between caffeine and coffee strength. You can also learn how to serve yourself the perfect java for your needs.

So let’s scroll down to discover the truth!

What Is Strong Coffee?

In coffee, strength refers to the brewing process. For example, the typical brew ratio of coffee to water is 1:15. Yet, strong coffee has a higher ratio, such as 1:10 or 1:12.

Espresso is strong coffee by definition because we brew it in a concentrated form. Meanwhile, weak coffee is made with not enough grounds to the water used.

People love strong coffee for multiple reasons. First, they may like the rich and bold aroma of the drink.

In addition to the taste, strong coffee offers a high energy boost. Thus, we can fight fatigue and focus on our work effectively.

Another reason is the coffee-drinking ritual. For example, some people only want a high-quality cup of coffee with a strong aroma.

In the end, people’s reasons for liking strong coffee may differ based on their tastes, lifestyles, and cultures.

And interestingly, some people love strong coffee because they think there is more caffeine. But is it true? We will talk about it right now.

 Strong coffee has a bold flavor

Does Strong Coffee Have More Caffeine?

Not really. Strong coffee doesn’t always have more caffeine. So you need to consider other factors to measure the caffeine amount in your java.

The idea of strong coffee is that you put more coffee into it while reducing the water content. Hence, it will be more abundant in caffeine than a regular cup.

However, the caffeine content only depends on different factors, such as the bean type, ground size, and brewing method.

For example, there is 90 mg of caffeine in 15 mg of ground coffee. The caffeine content will be the same even if you add less water to have a strong coffee.

So, the strength doesn’t necessarily affect the caffeine. But what will? We will discuss all the determinants right here.

Coffee Bean Type

Let’s check the bean type first. There are two primary types of coffee beans: Robusta and Arabica. Interestingly, these two beans have different caffeine levels.

More specifically, Robusta beans contain twice as much caffeine as Arabica beans. Hence, if you compare a cup of strong Arabica coffee and a cup of standard Robusta coffee, you can’t tell which has more caffeine.

Robusta beans contain more caffeine than Arabica

Coffee Ground Size

Aside from the coffee bean type, the size of coffee grinds will impact caffeine levels. The modification, though, is minor.

Please note that extraction plays a vital role in the brewing process because it’s where the caffeine, aroma, and flavor arise.

The critical factor in the extraction phase is surface area. Since finer grinds have more exposed surface area, they will hasten and simplify the extraction process.

Nevertheless, coffee grinds don’t always change the extraction or caffeine content of the drink. Instead, the brewing method is a more significant factor.

Brewing Method

As aforementioned, the brewing method will determine your java’s caffeine content. It’s because some methods require a higher level of extraction.

For example, you can soak the coffee grinds in boiling water. Then, you will get a cup of coffee with more caffeine.

But remember that brewing methods are not the only determinant, even though they will affect your beverage’s drink.

In general, it would be best to experience different brewing methods. You will soon find the best flavor with the strongest coffee.

The brewing method plays an important role

How to Make A Strong Coffee?

You can use the AeroPress coffee maker to prepare a cup of strong coffee. There are two ways to do it.

Classic coffee

First, prepare 15 grams of finely ground coffee and 30 grams of water. Then, the coffee-to-water ratio for your drink will be 1:2.

After gathering the ingredients, please follow these steps:

  • Boil water and let it cool slightly.
  • Assemble the coffee maker.
  • Add ground coffee to the brewing chamber.
  • Pour hot water into the ground coffee until it reaches number 1, then stir gently.
  • Let your coffee steep for one to two minutes.
  • Gently press the plunger to extract the coffee into your cup.

Drip-style coffee

On the other hand, this recipe will be ideal if you love filtered coffee. The instructions for making a drip-style coffee are as follows:

  • Boil the water.
  • Put the ground coffee into the brewing chamber of the coffee maker.
  • Add hot water to the chamber until it reaches number 4.
  • Wait for the extracted coffee to drip through the filter.
Two ways to have strong coffee

How Much Caffeine is Too Much?

The answer depends on your age, weight, health, and caffeine sensitivity. It’s because the reaction to caffeine differs significantly from person to person.

According to the U.S. Food and Drug Administration (FDA), you should not take more than 400 mg of caffeine a day. Yet, some people may be more sensitive to caffeine than others.

For example, two cups of coffee may seem fine to you. However, your friend may experience anxiety, insomnia, jitters, or headaches. And in worst cases, excessive consumption may cause severe health problems, such as:

  • High blood pressure
  • Heart palpitations
  • Cardiac arrest
  • Difficulty breathing

If you don’t know your safe limits, contact your physician for help. They will give you advice based on your health status.

The question now is, “How can people with caffeine sensitivity drink coffee?” Fortunately, there are several ways to adjust the caffeine content in your java.

We have discussed some determinants of caffeine. Hence, you can work with them to get the desired caffeine content.

Another easy way to try is to drink decaf coffee. Have you ever heard about that? If not, check this video to learn:

Popular Types of Strong Coffee

If you love strong coffee, there are many options to choose from. Each has a unique flavor, aroma, and characteristics.

In this section, we will highlight some terrific types of strong coffee. By reading through all of those ideas, you will understand more about how the brewing method affects your coffee.


Espresso is concentrated coffee. You can make it by using high pressure to push hot water through finely-ground coffee.

The result of this method is a bold, strong coffee flavor. You can also use espresso as a base for other coffee beverages. We highly recommend Americanos, cappuccinos, and lattes for this experience.

French Press

To make French Press, you will steep coarsely ground coffee in hot water for a few minutes. Then, press the coffee to the bottom of the pot. The outcome of this method is rich java.

Cold Brew

As the name implies, you need cold water to prepare a cup of cold brew. This method involves steeping coarsely-ground coffee in cold water for a few hours. Finally, you will get a smooth and less acidic coffee.

Turkish Coffee

This beverage calls for finely ground beans. To be more specific, you will boil the coffee grounds with water and serve the liquid with cardamom. In the end, your coffee will have a thick texture.

Cuban Coffee

Cuban coffee is a stronger version of espresso. Hence, coffee drinkers often use it with demerara sugar to have a bold yet sweet flavor.

Black Coffee

If you like classic java, go for black coffee. This beverage only needs coffee beans and hot water. Besides, you can use any roast levels and brewing methods to adjust its strength and flavor.

There are many types of strong coffee

Frequently Asked Questions

Espresso: 1:2
Cold Brew: 1:4
French Press: 1:12

Is it OK to drink very strong coffee?

Yes, if you drink it in moderation. Otherwise, you may encounter side effects, such as diarrhea, insomnia, headache, etc.

Although strong coffee doesn’t necessarily contain much caffeine, you should still be aware of your caffeine intake. As a result, limit your coffee consumption to a safe rate, and stop when you experience adverse effects.

Which coffee is highest in caffeine?

Coffee made from Robusta coffee beans has the highest caffeine content. However, we can’t name the exact type of coffee because the beans are not the only determinant.

Nevertheless, the caffeine content in a cup of coffee also depends on the brewing method and ground size. That’s why we have hundreds of coffee types with only two coffee beans.

Does stronger coffee give you more energy?

Not really, because strong coffee doesn’t contain more caffeine. Yet, you may still feel more energy due to the more robust aroma and flavor. They will quickly give you a stimulating effect.

In addition, the act of drinking coffee is already energizing to many people. So, some may not care about the caffeine content or the strength.

What does strong coffee do to your brain?

Strong coffee, with its caffeine and other ingredients, will affect your brain in these ways:

– First, it will increase your brain activities to improve your mental focus.
– Also, the levels of dopamine and other neurotransmitters will increase. Since they connect to your feelings, your mood may improve.
– Another effect of caffeine on your brain is improving your cognitive function and memory. Hence, you can handle mental tasks effectively.
– Last but not least, caffeine helps reduce fatigue. It performs this task by preventing adenosine receptors in your brain.


Coffee strength refers to its coffee-to-water ratio. Hence, stronger coffee doesn’t have more caffeine than standard one.

In fact, strong coffee has a bolder, richer flavor and aroma. So even if the caffeine content doesn’t change, it can also give you an exciting experience.

After all, depending on the preparation method, you will enjoy the best cup of coffee for your preferences. And feel free to contact us for any difficulty while making it.
