It’s crucial to know how much caffeine you’re sipping, especially with something as potent as a double shot of espresso.

Let’s compare: A typical 12 oz serving of brewed coffee has about 95 milligrams of caffeine. But when it comes to espresso, size can be deceiving. In just 2 oz, a double shot of espresso (or doppio) averages around 80 milligrams of caffeine, with some variations depending on where it’s made.

  1. What exactly is in a double shot of espresso in terms of caffeine content?
  2. How does the double shot compare to other caffeinated drinks?
  3. What should you consider when calculating your caffeine intake from espresso?

With these insights, you’re on your way to becoming an espresso caffeine expert.

How Much Caffeine in a Double Shot of Espresso

How much caffeine in double espresso? In a double shot of espresso or two shots, also known as doppio, you’ll find around 80 milligrams of caffeine on average. Different coffee shops or espresso machines may produce varying caffeine content in double shots. For example, a double shot of espresso at Starbucks contains approximately 150 milligrams of caffeine.

How Much Caffeine Is In A Double Shot of Espresso?

Typically, a double shot of espresso contains around 80 milligrams of caffeine. However, this value can vary depending on many factors, such as the coffee beans, the roast, the brewing method, and the serving size.

Caffeine in double shot espresso values can range from 58 mg to 185 mg, but a common estimation is around 150 mg for two shots.

To put this caffeine content in perspective:

  • Single Shot Espresso: 29-100 mg (often around 75 mg)
  • Decaf Espresso, Single Shot: about 8 mg

Remember that espresso-based drinks like lattes and cappuccinos will have different caffeine levels depending on the number of espresso shots used in the drink.

Also, it’s worth noting that coffee shops and brands might serve different amounts of caffeine in their double-shot espressos. For example, a double shot espresso at Starbucks contains nearly 150 mg of caffeine.

What Affects The Double Shot Espresso Caffeine Content

Coffee Beans

Different types of coffee beans have different levels of caffeine content. Arabica beans, which are the most common, have less caffeine than the more robust Robusta beans. When choosing coffee beans for your espresso, remember that the type of bean can impact the caffeine content.


The fineness of the grind also affects the caffeine content in your espresso. Finer grinds have more surface area, allowing for a more efficient extraction of caffeine during brewing.

To get the most caffeine out of your coffee beans, it’s important to select a grind that’s appropriate for espresso, which is typically finer than what you’d use for drip coffee.

Coffee Bean Roasting

The roasting process can have a significant effect on the caffeine content of your espresso. Lighter roasts retain more caffeine than darker roasts, as caffeine can be lost during roasting.

Opt for a lighter roast coffee bean if you prefer a higher caffeine content in your espresso.

Serving Size

Lastly, the serving size of your espresso shot impacts the overall caffeine content. A single shot of espresso is generally about 30-50 ml (1-1.75 oz) and contains approximately 63-75 mg of caffeine.

On the other hand, a double shot of espresso will contain roughly 125-150 mg of caffeine, depending on the factors mentioned above.

What Is a Double Shot of Espresso

Espresso Shot

An espresso shot is a concentrated coffee drink that pushes pressurized hot water through densely packed coffee grounds. Rich, complex, and highly caffeinated, a single shot of espresso is typically one ounce and has around 64 milligrams of caffeine.

Espresso is the base for many coffee beverages and is a favorite for coffee enthusiasts seeking an intense coffee experience.


When you hear about a double espresso or a “doppio,” it refers to two espresso shots in one serving. A doppio is simply double the amount of coffee grounds and hot water used in a single espresso shot. This makes it a two-ounce coffee drink, often containing approximately 130 milligrams of caffeine.

You can expect around 150 milligrams of caffeine in a doppio at Starbucks.

A double espresso has more caffeine and enhances the flavor profile of the drink, offering twice the rich and bold taste of a single espresso. The caffeine content in a doppio can vary depending on the type of coffee bean used and how the drink is prepared.

For example, a doppio made with Arabica beans may contain less caffeine than one made with Robusta beans.

Here’s a quick summary of the differences between an espresso shot and a doppio:

  • Espresso shot: One ounce, approximately 64 milligrams of caffeine.
  • Doppio: Two ounces, approximately 130 milligrams of caffeine (150 milligrams at Starbucks).

When choosing your coffee drink, consider the intensity of flavor you prefer and your desired caffeine intake. A doppio is an excellent option if you’re looking for a more robust and concentrated coffee experience with a higher caffeine content.

Enjoy experimenting with different beans and brewing techniques to find the perfect double shot of espresso that suits your taste buds.

Comparing Caffeine in Espresso to Other Beverages

Now that you know a double shot of espresso contains approximately 150 mg of caffeine, let’s see how this compares to other popular caffeinated beverages.

Of course, these show the total amount in a normal-sized drink. A double espresso is only around 2 ozs, so I have included the amount of caffeine in 2 ozs to compare the caffeine strength relative to 2 espresso shots.

We’ll examine tea, soda, and energy drinks and their caffeine content.


Tea comes in a wide variety of flavors and caffeine levels. While some teas have little to no caffeine, others can pack quite a punch. Here are some common types of tea and their average caffeine content:

DrinkRegular ServingCaffeine In 2 ounces
Green tea20-45 mg per 8 oz5-12 mg
Black tea40-70 mg per 8 oz10-18 mg
Oolong tea30-50 mg per 8 oz7-13 mg
White tea15-30 mg per 8 oz4-7 mg

As you can see, even the most caffeinated tea has less caffeine than a double shot of espresso. However, remember that the caffeine content can vary depending on factors such as brewing time, water temperature, and the tea blend.


Soda, or soft drinks, come in a variety of caffeine levels. Some popular soda options and their caffeine content include:

DrinkRegular ServingCaffeine in 2 ounces
Coca-Cola34 mg per 12 oz5.6 mg
Pepsi38 mg per 12 oz6.3 mg
Mountain Dew54 mg per 12 oz9 mg
Dr. Pepper41 mg per 12 oz6.8 mg

Compared to a double shot of espresso, the caffeine levels in soda are significantly lower.

Energy Drinks

Energy drinks are known for their high caffeine content and often appeal to those seeking an energy boost. Some popular energy drinks and their caffeine content are:

DrinkRegular ServingCaffeine in 2 ounces
Red Bull80 mg per 8.4 oz19 mg
Monster Energy160 mg per 16 oz20 mg
Rockstar240 mg per 16 oz30 mg
5-hour Energy200 mg per 2 oz200 mg

When comparing energy drinks to a double shot of espresso, you’ll find a wide range of caffeine amounts. Some, like Red Bull, contain less caffeine, while others, such as 5-hour Energy, have significantly more than a double shot.

Energy drinks often contain additional stimulants and other ingredients that can affect how your body responds to caffeine.

Calculating Your Caffeine Intake

how much caffeine in two shots of espresso

In this section, we will cover how to calculate the caffeine intake from a double shot of espresso and its relation to the recommended maximum daily dose of caffeine.

Maximum Dose

It’s important to be mindful of your caffeine consumption, as excessive intake may cause adverse health effects. Experts recommend a daily maximum of 400 mg of caffeine for healthy adults.

However, pregnant women, children, and those with specific health conditions should consult a physician for safe, moderate consumption values.

Total Caffeine (mg)

To determine the total caffeine intake from a double shot of espresso, let’s first understand its caffeine content. A double espresso typically contains around 80 milligrams of caffeine, slightly less than a regular cup of coffee, which has around 95 milligrams of caffeine.

Now that you know the amount of caffeine in a double espresso, you can calculate your daily intake and compare it to the recommended maximum dose.

For example, if you consume:

  • Two double shots of espresso: 160 mg (80 mg x 2) of caffeine
  • One cup of coffee: 95 mg of caffeine

In this scenario, your total daily caffeine intake would be 255 mg (160 mg + 95 mg), well within the recommended daily maximum of 400 mg.

Remember that other sources of caffeine, such as tea, soda, and energy drinks, can also contribute to your daily intake. Be sure to account for these when calculating your total consumption.

By monitoring your caffeine intake from sources like double shots of espresso and other beverages, you can enjoy the benefits of coffee and stay within healthy limits.
