Espresso is a beloved coffee beverage known for its concentrated, bold flavor and robust caffeine content. Many coffee drinkers, particularly those new to espresso, are curious about how much caffeine in espresso is typically present. Understanding the caffeine in espresso is crucial for both casual drinkers and serious coffee enthusiasts who want to enjoy their coffee in moderation or maximize their caffeine intake.
In this article, FnB Tech will delve into the factors that determine how much caffeine is in an espresso shot, how it compares to other types of coffee, and other key aspects of caffeine in espresso that will help you make informed decisions when ordering or brewing espresso.

What Is Espresso?
Espresso is a type of coffee made by forcing hot water through finely-ground coffee beans under high pressure. The result is a small but strong shot of coffee that serves as the base for various other coffee drinks, such as lattes, cappuccinos, and macchiatos. Unlike drip coffee, which is brewed over a longer period, espresso is made quickly and is characterized by its concentrated flavor and high caffeine content.
A standard espresso shot, or ristretto, is usually served in a small demitasse cup and measures about 1 ounce (30 milliliters). Despite its small size, espresso is packed with caffeine and intense flavor, making it a popular choice among coffee aficionados.

Caffeine in Espresso
The caffeine content in espresso is one of the key factors that make it so popular and potent. A standard single shot of espresso typically contains around 63 milligrams of caffeine. However, the amount of caffeine in espresso can vary depending on various factors, such as the type of beans used, the grind size, and the brewing time.
How Much Caffeine in a Shot of Espresso?
The caffeine in espresso varies depending on several factors, but the general consensus is that a single shot of espresso contains approximately 63 milligrams of caffeine. This is an average figure, and the actual caffeine content can range anywhere from 50 milligrams to 75 milligrams, depending on factors like the type of coffee bean and the grind size.
Here are the primary factors that influence how much caffeine in espresso is extracted:
-
Coffee Bean Type: Espresso is usually made with either Arabica or Robusta beans. Robusta beans contain significantly more caffeine than Arabica beans. If your espresso is made with Robusta beans, the caffeine content will naturally be higher.
-
Grind Size: The grind of your coffee beans affects how much caffeine is extracted during the brewing process. Espresso requires a fine grind to maximize the surface area, which allows for more efficient caffeine extraction.
-
Brewing Time and Pressure: Espresso is brewed under high pressure, which is essential for extracting caffeine from the coffee grounds. The standard brewing time for espresso is around 25 to 30 seconds. A longer brewing time can lead to more caffeine extraction, but espresso is typically brewed in a shorter time than other methods like French press or drip coffee.
-
Serving Size: Espresso is usually served in 1-ounce portions. If you choose a double shot (a doppio), the caffeine content will naturally double, with approximately 126 milligrams of caffeine.
Comparing Caffeine in Espresso to Other Coffee Drinks
When comparing caffeine in espresso to other coffee drinks, it’s important to consider both the concentration of caffeine and the total volume of the beverage. While espresso contains more caffeine per ounce than most other coffee drinks, the total caffeine intake depends on the amount you consume.
Drip Coffee vs. Espresso
A typical 8-ounce cup of drip coffee contains approximately 95 milligrams of caffeine, which is more than a single shot of espresso. However, drip coffee is consumed in much larger quantities.
The caffeine concentration per ounce in drip coffee is lower, around 12 milligrams per ounce, compared to espresso, which contains about 63 milligrams per ounce.
Americano vs. Espresso
An Americano is a coffee drink made by adding hot water to one or more shots of espresso. While the caffeine content of an Americano is similar to that of espresso, the volume is much larger.
A typical Americano made with two shots of espresso contains around 126 milligrams of caffeine, which is more than a single shot of espresso but still roughly equivalent to the caffeine content of a standard cup of drip coffee.
Latte and Cappuccino vs. Espresso
Lattes and cappuccinos are espresso-based drinks that combine espresso with steamed milk. The caffeine content of these drinks depends on the number of espresso shots used.
For example, a single shot of espresso in a latte or cappuccino contains around 63 milligrams of caffeine. However, the milk in these beverages dilutes the flavor and caffeine concentration, making them less potent than a straight shot of espresso.
Cold Brew vs. Espresso
Cold brew coffee is made by steeping coffee grounds in cold water for an extended period, usually between 12 and 24 hours. As a result, cold brew tends to be less acidic and smoother than regular brewed coffee. A typical 16-ounce serving of cold brew contains about 200 milligrams of caffeine, which is significantly more than a single shot of espresso.
However, cold brew has a lower caffeine concentration per ounce compared to espresso, as it is consumed in much larger quantities.

Factors That Influence Caffeine Content in Espresso
Several factors influence the amount of caffeine in espresso, and understanding these factors can help you control how much caffeine you’re consuming with each shot.
1. Coffee Bean Type
The type of coffee bean used plays a crucial role in determining the caffeine content of your espresso. Robusta beans, known for their stronger flavor, contain nearly twice as much caffeine as Arabica beans. As a result, espresso made with Robusta beans will generally have a higher caffeine content than one made with Arabica beans.
2. Grind Size
The grind size affects how efficiently the caffeine is extracted during brewing. Espresso requires a fine grind to maximize the surface area of the coffee grounds, which leads to more efficient extraction.
If the grind is too coarse, the water will flow through the coffee grounds too quickly, resulting in less caffeine being extracted. On the other hand, a grind that is too fine can cause over-extraction, leading to a bitter taste and possible under-extraction of caffeine.
3. Brew Time and Pressure
Espresso is brewed under high pressure, which helps extract caffeine from the coffee grounds. The pressure and brewing time are crucial in determining how much caffeine is extracted.
A typical espresso shot is brewed in about 25 to 30 seconds, which allows for optimal extraction of caffeine and flavor. Any variation in brewing time or pressure can result in a stronger or weaker espresso shot.
4. Serving Size
The size of your espresso shot determines how much caffeine you’ll consume. A standard espresso shot is typically 1 ounce, but if you order a double shot, you’ll get twice the amount of caffeine.
A double shot of espresso contains about 126 milligrams of caffeine, while a triple or quad shot would contain even more.
Conclusion
In conclusion, the amount of caffeine in espresso is generally around 63 milligrams per shot, though this can vary based on factors like the type of coffee bean used, the grind size, brewing pressure, and time. Although espresso is highly concentrated in terms of caffeine per ounce, the total caffeine intake will depend on the size of your espresso shot.
If you’re curious about how much caffeine in a shot of espresso is right for you, it ultimately depends on your individual caffeine tolerance and your preferences. Espresso is a great choice for those who enjoy a bold, concentrated coffee flavor with a significant caffeine boost in a small volume, but you can always adjust your intake by choosing larger servings or opting for drinks with more espresso shots.
Understanding the caffeine content in espresso allows you to enjoy your coffee experience while being mindful of how much caffeine you’re consuming.
