A nice cup of coffee is the perfect start of any day, especially if you’re headed to work next. Yet, you may find yourself unsatisfied with your usual dosage of caffeine. This might lead you to ask the question: which coffee has the most caffeine?

The quick answer is that there are several highly-caffeinated coffee brands that have between 58 mg and 1,555 mg of caffeine. Devil’s Mountain Black Label coffee has the most caffeine per serving at 1,555 mg every 12 ounces.

But there are a lot more factors that play into what coffee has the most caffeine. In this article, we’ll answer this question and talk about how some factors affect the amount of caffeine in coffee beans.

Let’s dive in!

Which Coffee Has the Most Caffeine?

To understand the whole picture, you might want to look at how some coffee types differ according to their caffeine amount.

Therefore, we’ve decided to include this brief comparison between some popular types of coffee.

Coffee Type Serving Size Caffeine Per Oz.
Decaf coffee (instant) 8 oz. 0.25 – 0.38 mg
Decaf coffee (brewed) 8 oz. 0.38 – 0.5 mg
Drip coffee 8 oz. 8.13 – 15 mg
Brewed coffee 8 oz. 11.88 mg
Cold-brew coffee 16 oz. 12.5 mg
Espresso 2 oz. (1 shot) 30 – 51 mg
Highly-caffeinated coffee 12 oz. 58 – 77 mg

As you can see, highly-caffeinated coffee has the most caffeine out of the previous table. Some well-known brands that produce this type of coffee are:

But what are the factors that lead to this high concentration of coffee? We’re about to find out.

Bean Type and Caffeine Content

The first thing you should know is that some types of coffee beans have more caffeine than others naturally. So, to make our research thorough, we must determine which type has more caffeine.

If you don’t already know, there are two types of coffee beans that you should find on the market. Namely, they’re Arabica beans and Robusta beans.

Arabica Beans

Arabica beans are more premium. Planting them requires specific weather conditions. Plus, these beans need special care and growing techniques. As a result, they can be much more expensive than Robusta beans.

Also, Arabica coffee usually has this sweet, fruity flavor, which makes it a favorite of many people all over the world.

Robusta Beans

On the other hand, Robusta coffee beans are easier to farm. So, you’ll find them at a much more affordable price than Arabica beans.

Plus, these banes are famous for their strong and earthy taste. Of course, Robusta beans have their own fans as well.

But which one of these two bean types has more caffeine?

You might be surprised that even though Arabica beans are more high-quality, they have a lot less caffeine than Robusta beans. In fact, Robusta coffee has twice as much caffeine as Arabica coffee.

The good news is that Robusta coffee is way more available than Arabica. You should find it at your nearby supermarket with no trouble. Yes, Robusta beans can come in cheap blends, but if you do some digging, you should find high-quality roasts as well.

Roast Type and Caffeine Content

The next thing that affects the amount of caffeine in a coffee cup is the roast type. The majority of people assume that darker beans equal more caffeine, but this isn’t the right way to look at it.

Furthermore, you might think that a light profile roast includes more caffeine. Again, this isn’t entirely correct.

Much to our surprise, it was found that a lightly roasted bean has as much caffeine as a dark roasted bean. However, the roast type still affects the caffeine inside coffee beans in another way.

See, the roasting process causes the coffee beans to lose some of their mass. Therefore, dark-roasted coffee weighs less than light-roasted beans.

As a result, a pound of dark-roasted beans will include a bit more bean count than a pound of light-roasted beans. Thus, this pound of dark-roasted beans will have more caffeine.

But what happens if we change the scenario?

If you’re ready to brew a cup of coffee in the morning, chances are you’ll measure your beans by volume or weight. In each of those cases, the caffeine content will change according to the method.

By Volume

If you use a scoop to measure your beans, then a cup of light-roast beans will include more caffeine than dark-roast beans.

This is because the volume of beans you’ll use for both roasts will be equal. And since dark-roasted coffee has less mass, then, in this case, light-roast beans will produce a more caffeinated cup of coffee.

By Weight

Now, if you measure your coffee beans by weight, then you’ll automatically use more dark-roast bean count since it’s smaller in size.

Therefore, if you measure out, let’s say, 20 grams of both dark and light roast coffee beans, the dark-roast beans will have more caffeine.

Beverage Type and Caffeine Content

Last but not least, the way you brew your coffee can also affect its caffeine content. You may have already noticed this difference after taking a look at the table at the top.

An average decaf coffee cup has the least caffeine, followed by drip coffee, then espresso. However, the caffeine that exists in a coffee cup also depends on the serving size.

See, an 8-oz cup of drip coffee has around 94.8 mg of caffeine. On the other hand, a shot of espresso, which is about 1-oz, has 62.8 mg of caffeine.

So, if you want to go for the beverage with the most caffeine, drip coffee can be the best choice. Yet, the most remarkable thing about espresso is that it has 40-55 mg of caffeine per ounce.

You don’t get that with drip coffee, where it only includes 9-18 mg of caffeine per ounce.

Therefore, to stay on the right path, you should create a nice balance between the beverage type and serving size. For instance, a double shot of espresso undoubtedly has more caffeine than an average cup of drip coffee.

Using the chart that we’ve included above, you can easily brew or order your perfect cup of coffee. You should be able to control your caffeine intake based on the several points that we’ve discussed.

What are the health risks of consuming too much caffeine in coffee form?

As with anything in the world, too much coffee can lead to a multitude of side effects.

Anxiety

Too much caffeine could lead to anxiety. That’s because caffeine triggers the release of adrenaline, which gives you more energy. Thus, too much adrenaline in your system means additional anxiety and nervousness.

Insomnia

Yes, most of us rely on coffee to keep us up at night if we have plenty of work to do. Yet, too much coffee can make you restless, causing your brain to remain alert for more time than you need.

In the long term, a person who is used to high caffeine intake can find it harder to sleep at night. They might need a long time before they can relax, not to mention that they tend to sleep for only a few hours each night.

High Blood Pressure

Generally, coffee doesn’t lead to high blood pressure if it’s consumed in moderation. Still, for people with heart conditions, too much coffee can be risky.

Also, studies have found that caffeine can cause temporary high blood pressure. This is usually the case if the person drinking coffee isn’t used to it.

In fact, a high intake of caffeine can raise blood pressure in healthy people during exercise.

Therefore, to keep yourself in a safe zone, make sure that you stick to the recommended amount of caffeine per day. Even if you don’t have any health issues, moderation is always a good idea.
