How Much Caffeine in an Espresso Bean?

Being a pure coffee lover, you would probably know that espresso is one of the most concentrated and flavorful ways to enjoy your favorite brew. But can you calculate how much caffeine in an espresso bean?

And, how does it compare to other types of coffee or chocolate-covered espresso beans? Well, stay informed as we answer all of these questions with definitive answers throughout this extensive guide!

What is Espresso?

Know anything about espresso? Well, it is a type of coffee easily extracted by forcing hot water through finely-ground coffee beans at really high pressure. And that results in a thick, rich, and aromatic liquid that is usually served in small shots of about 1-2 ounces.

So, that is the exact reason why espresso happens to be the primary base for many popular coffee drinks, such as cappuccino, latte, macchiato, and mocha.

Know that, espresso has never been a specific kind of coffee bean or roast, but it is rather a method of preparation. You can obviously use any kind of coffee bean to make espresso.

Typically, espresso beans are roasted to a medium or dark level, which gives them a stronger flavor and less acidity.

Some common varieties of espresso beans are;

• Arabica
• Robusta
• And the blend of both

How Much Caffeine in an Espresso Machine?

On a serious note, the amount of caffeine in an espresso machine greatly depends on several prime factors, such as the type and amount of coffee beans used, the size and strength of the shot, and the brewing time and temperature. However, on average, a single shot of espresso (1 ounce) has about 64 mg of caffeine, while a double shot (2 ounces) has about 80 mg. That means an espresso machine can produce about 32-40 mg of caffeine per ounce of liquid.

To put this into clear perspective, a typical 8-ounce cup of drip coffee will have around 95 mg of caffeine, meaning that it has about 12 mg of caffeine per ounce. So, an espresso machine can deliver about three times more caffeine per ounce than a drip coffee maker. That’s why espresso is often considered a more potent and energizing drink than a regular cup of coffee.

But again, this doesn’t mean that espresso will always have more caffeine than coffee in absolute terms. Because espresso is served in smaller portions than drip coffee, you may end up consuming less caffeine overall.

For example, if you drink one shot of espresso (64 mg) versus one cup of drip coffee (95 mg), you’re actually ending up having less caffeine from the espresso. But on the other hand, when you try two shots of espresso (160 mg) versus one cup of drip coffee (95 mg), you’re going to retain more caffeine from the espresso alone.

How Much Caffeine in Chocolate-Covered Espresso Beans?

Wow! How tasty the chocolate-covered espresso beans are? And when you pick those sweet and crunchy beans in order to get your caffeine fix, the temptation would be end-class!

Those roasted coffee beans coated in milk or dark chocolate, and adding some extra flavor and calories to your snack. But did you ever ask yourself how much caffeine the bean contains?

Remember that amount of caffeine in chocolate-covered espresso beans always varies depending on the source. But based upon the rough estimation, a single chocolate-covered coffee bean may contain around 12 mg of caffeine per bean, and that also includes the caffeine dipped into the chocolate. However, some sources state that there are about 80 mg of caffeine per ounce in chocolate-covered coffee beans, which is going to be about the same amount of caffeine as in a cup of regular coffee.

Whereas, a single chocolate-covered espresso bean contains between 6 and 13 mg of caffeine, with the chocolate covering contributing the remaining milligrams. Another source states that a single coffee bean covered in dark chocolate contains around 20-30 mg of caffeine, and a serving of chocolate-covered espresso beans contains between 150 to 175 mg of caffeine.

As you can see, there is quite a varied range of caffeine content in chocolate-covered espresso beans, so it’s best to check the product’s label before indulging.

Also, keep in mind that darker chocolates have more caffeine than milk or white chocolates. and that Robusta beans have more caffeine than Arabica beans.

So if you’re looking for a real jolt from your snack, always opt for dark chocolate-coated Robusta beans over other varieties.

Do Espresso Beans Have More Caffeine?

You may be wondering if the espresso bean has more caffeine than any other type of coffee bean. The answer is not so simple. Let’s play through some assumptions and calculations.

The amount of caffeine in a coffee bean depends on several factors, such as species, variety, growing conditions, processing methods, and roasting level.

Species of Beans

In general, there are two main species of coffee: Arabica and Robusta.

Arabica beans are more widely grown and consumed, and they have a smoother and more delicate flavor.

Whereas, Robusta beans are more resistant to pests and diseases, and they have a stronger and more bitter taste.

Robusta contains a larger volume of caffeine. On average, Robusta beans have over 2.9 mg of caffeine per gram, while Arabica beans only end up with around 1.9 mg of caffeine per gram. So, that clearly solves the myth Robusta beans have nearly 50% more caffeine than Arabica beans. However, this doesn’t mean that all espresso beans are Robusta.

In fact, the espresso blends primarily use a crossbreed of Arabica and Robusta beans to achieve and provide the sippers the balanced flavor and crema.

Roasting Level

Another easy-peasy factor that greatly determines the caffeine content of a coffee bean is the roasting level. Roasting is a whole lot of process where we have to heat the green coffee beans to produce flavor, aroma, and color.

Roasting is the real responsible for putting an effect over the induced amount of caffeine in each bean, but that does not go in the same way as you imagine. Contrary to popular belief, darker roasted beans do not exceed the caffeine amount of lighter roasted beans. In fact, the opposite is true.

And, that can easily result in a loss of mass and volume of the coffee beans, just because of the moisture evaporation and carbon dioxide release. What does that mean? To summarize the fact, the darker roasted beans will be immensely lighter and smaller than lighter roasted beans. But, the amount of caffeine in each bean remains relatively unchanged during roasting.

Thus, when you measure your coffee through weight, you will end up with more beans and more caffeine if you use a darker roast. But if you measure your coffee by volume, you will end up with fewer beans and less caffeine if you use a darker roast.

So, do espresso beans have more caffeine than other types of coffee beans?

Wait! It considerably depends on how you measure them and what kind of beans you use.

Whether you pick Robusta beans or a blend that contains Robusta, you will get more caffeine than Arabica beans or a blend that includes Arabica.

But when you measure your coffee by weight, you will get more caffeine if you use a darker roast than if you use a lighter roast.

And by going with measuring the coffee on the basis of volume, chances are you will get less amount of caffeine-containing darker roast than the lighter version.

How Much Caffeine Is Too Much?

Caffeine conforms to be a natural stimulant that can boost your mood, energy, and alertness. It comes with many health benefits, such as reducing your risk of diabetes and liver disease. But too much of it can trigger some negative impacts on your health, such as insomnia, anxiety, jitteriness, headaches, and most severely, heart palpitations.

According to the FDA, the recommended daily maximum caffeine intake should never pass beyond 400 mg for healthy adults. That amount is equivalent to over 4 cups of coffee, 10 cans of cola, or 2 energy drinks. However, the amount should vary depending on your age, weight, health conditions, and sensitivity to caffeine.

But, some people can definitely tolerate high volume of caffeine than others, and some may face unfavorable conditions even with consuming just a small amount.

Therefore, it is best to consume caffeine in moderate quantities and pay good attention to how it affects your body and mind. If you experience any unpleasant symptoms immediately after consuming caffeine, we advise you to cut back on your intake or just avoid it completely.

Most importantly, avoid taking caffeine late in the day especially around bedtime, as it can literally disturb your sleep cycle.

Conclusion

Espresso and chocolate-covered espresso beans are both delicious and super-caffeinated ways to enjoy coffee, but they both include different amounts of caffeine depending on various factors.

And espresso beans do not necessarily mean to be containing more caffeine than any other coffee beans, but they are far more concentrated and potent.

Now that you should be well aware of how much caffeine in an espresso bean, no? With all the benefits and drawbacks of caffeine consumption, it is important for you to always take it in moderation and detect how it affects your body and behavior!
