How Much Caffeine Is In Espresso and regular coffee?

You don’t “jump off the walls” with espresso, but you do get a little jolt of energy from a cup of regular coffee. In the minds of many, espresso and black coffee have roughly the same amount of caffeine, but it’s more complicated than that.

Let’s put the record straight with accurate caffeine numbers so you can better control your coffee intake and avoid the jitters or insomnia that comes with it.

There is 96 mg of caffeine in an eight-ounce cup of brewed coffee. 64 mg of caffeine are found in a typical one-ounce shot of espresso.

When it comes to caffeine content, an espresso shot is less potent than an entire cup of coffee. 

Caffeine and Coffee Beans

No such thing as “espresso” beans exist. Espresso beans aren’t any different than regular coffee beans. Almost 90% of the coffee sold in the United States is either Arabica or Robusta. 

Due to the deeper crema, Robusta beans are typically used in “Classic Italian” Espresso. Espresso in the United States is often made with Arabica beans, which have a more pronounced flavor. 

Coffee from Arabica beans contains about half as much caffeine as coffee from Robusta beans, so espresso produced from Robusta is more likely to have a higher caffeine concentration. As a result, the kind of coffee beans you use can make a difference. 

While the amount of caffeine in each beverage is essential, it’s also important to consider how quickly you’re likely to consume it.

How fast do you drink your coffee?

There’s no disputing the facts, but one crucial question remains unresolved. Why does a one-ounce espresso shot feel more potent than an eight-ounce cup of coffee?

The primary explanation is that you’re likely consuming the espresso far more quickly. European coffee consumers tend to enjoy their brews more slowly. However, espresso is typically consumed in one gulp.

Caffeine’s effects are felt within 15 minutes. Thus, an espresso shot’s 64 milligrams of caffeine feels more potent than a cup of coffee’s 96 milligrams of caffeine, which is drunk slowly.

Espresso has a lot of caffeine, but how much?

Do they serve espresso-based beverages in your local neighborhood coffee shop? A lot relies on how much espresso is used and how it’s prepared.
