How Much Caffeine in a Shot of Espresso
What Defines a Shot of Espresso?
A shot of espresso is a small, concentrated coffee beverage made by forcing hot water through finely-ground coffee beans under high pressure. This method creates a rich and robust flavor profile distinct from other brewing methods.
Typically, a shot of espresso measures about 1 ounce (30 ml) and is characterized by its strong taste and velvety crema—a layer of foam on top that enhances its texture. The brewing process takes approximately 20-30 seconds, balancing strength and flavor in this tiny yet potent drink.
Caffeine Content in a Single Shot
A single shot of espresso contains approximately 63 milligrams of caffeine, making it one of the most concentrated coffee beverages. While the serving size is smaller than drip coffee, the caffeine punch per ounce is much higher. However, this amount can vary slightly depending on factors like the type of coffee bean used and brewing conditions. Despite its small size, this caffeine content makes espresso a popular choice for those seeking an instant energy boost.
Double Shots and Their Caffeine
A double shot of espresso, often called a “doppio,” is simply double the quantity of a single shot. It’s made by using twice the coffee grounds and yields approximately 2 ounces (60 ml) of espresso.
In terms of caffeine, a double shot typically contains about 125 milligrams, offering double the kick of a single shot. Many coffee drinkers prefer this option for its stronger flavor and higher caffeine content, especially when paired with milk in espresso-based drinks.
Factors Affecting Caffeine Levels
Bean Type and Roast
The type of coffee bean greatly influences the caffeine content in espresso. Arabica beans are known for their smoother flavor and typically contain less caffeine than Robusta beans, which are stronger and more bitter. Additionally, the roast level matters—lighter roasts tend to retain more caffeine, while darker roasts lose some caffeine during the roasting process.
Brewing Time
The amount of time hot water is in contact with the coffee grounds affects caffeine extraction. Longer brewing times can lead to higher caffeine levels, as more caffeine is extracted into the espresso. However, over-extraction can also make the coffee taste bitter, so a balance is crucial.
Grind Size
The grind size of coffee beans impacts the rate of caffeine extraction. Finely ground coffee allows more surface area for the water to extract caffeine, resulting in a stronger espresso. Coarser grinds, on the other hand, may lead to weaker caffeine extraction, altering the final caffeine content.
Espresso-Based Drinks and Caffeine
Lattes
A latte combines a shot (or double shot) of espresso with steamed milk and a small amount of foam. While the caffeine content remains around 63–125 milligrams, the milk dilutes the flavor, making it a smoother and creamier beverage.
Cappuccinos
A cappuccino uses equal parts espresso, steamed milk, and foam. The espresso content stays the same as a latte, but the airy foam creates a lighter, frothy texture. The caffeine content is typically 63–125 milligrams depending on the shot size.
Macchiatos
A macchiato features a shot of espresso “stained” with a small amount of steamed milk or foam. With minimal dilution, it retains its bold flavor and contains 63 milligrams of caffeine per shot.
Americano
An Americano is made by diluting espresso with hot water, creating a lighter flavor profile without reducing the caffeine. A single-shot Americano has about 63 milligrams of caffeine, while a double shot offers 125 milligrams.
| Drinks | Caffeine Content |
|---|---|
| Latte | 63–125 mg |
| Cappuccino | 63–125 mg |
| Macchiato | 63 mg |
| Americano | 63–125 mg |

Key Ingredients in Espresso Coffee
Espresso is a simple yet complex drink with a rich flavor profile, achieved through a combination of carefully selected ingredients and precise preparation methods. The following are the key ingredients:
- Coffee Beans: High-quality coffee beans, usually Arabica or Robusta, are essential. The choice of beans impacts the flavor, strength, and aroma of the espresso.
- Water: Purified water is crucial to ensure a clean and balanced extraction, as impurities can alter the taste of the espresso.
- Pressure: While not a physical ingredient, the use of high pressure (9 bars) during brewing is fundamental to creating espresso’s signature crema and concentrated flavor.
- Grind Size: Finely-ground coffee ensures maximum surface area for water to extract the rich flavors and caffeine during the brewing process.
- Heat: The ideal water temperature for brewing espresso is 195–205°F (90–96°C), which ensures optimal extraction without burning the coffee.
Comparing Espresso to Other Coffee Types
Drip Coffee
Drip coffee, brewed by passing hot water through coffee grounds in a filter, typically contains 95 milligrams of caffeine per 8-ounce cup. While it has more caffeine per serving, its concentration is lower than espresso.
Cold Brew
Cold brew coffee is steeped in cold water for several hours, resulting in a smooth yet strong flavor. An 8-ounce serving can contain up to 200 milligrams of caffeine, making it significantly stronger than espresso in total caffeine.
Instant Coffee
Instant coffee is made by rehydrating freeze-dried coffee powder with hot water. Its caffeine content ranges from 30 to 90 milligrams per cup, depending on the brand, making it less potent than espresso. How Much Caffeine in a Shot of Espresso
Decaf Espresso: Is It Truly Caffeine-Free?
Despite its name, decaf espresso is not entirely free of caffeine. The decaffeination process removes about 97% of the caffeine, but a small amount remains. On average, a shot of decaf espresso contains 3–12 milligrams of caffeine, depending on the method used. For individuals sensitive to caffeine, this is a great alternative while still enjoying the rich flavor of espresso.
Alternatives to Espresso Coffee
If espresso isn’t your cup of coffee, there are several delicious alternatives with varying caffeine levels and flavor profiles. Here are eight popular choices:
Drip Coffee
Drip coffee is brewed by passing hot water through coffee grounds in a filter, producing a lighter, less concentrated drink. While it has a smoother taste, its caffeine content per serving is higher—about 95 milligrams per 8-ounce cup—making it a great alternative for those seeking a milder flavor but a longer-lasting energy boost.
French Press
French press coffee is made by steeping coarse coffee grounds in hot water and then pressing them with a plunger. The result is a rich, full-bodied coffee with approximately 80–100 milligrams of caffeine per 8-ounce serving. This method is ideal for those who enjoy robust flavors without the intensity of espresso.
Cold Brew
Cold brew coffee is steeped in cold water for 12-24 hours, resulting in a smooth, less acidic drink. It typically contains a higher caffeine content, ranging from 150 to 200 milligrams per 8-ounce serving, making it perfect for those who prefer their coffee cold and potent.
Americano
An Americano is made by diluting a shot (or double shot) of espresso with hot water. This alternative retains the bold espresso flavor but has a lighter taste and contains about 63–125 milligrams of caffeine, depending on the number of shots used.
Macchiato
A Caffè Macchiato offers a smaller, more concentrated drink made with a shot of espresso “stained” with milk. With 63 milligrams of caffeine per shot, it’s a great choice for those who want a slight twist on traditional espresso.
Cappuccino
Cappuccino combines espresso with equal parts steamed milk and foam, creating a creamy, frothy texture. Its caffeine content is similar to espresso—63–125 milligrams—but the milk balances its intensity, making it a gentler alternative.
Turkish Coffee
Turkish coffee is prepared by boiling finely-ground coffee with water and sugar, creating a thick, unfiltered drink. It contains approximately 50–65 milligrams of caffeine per 2-ounce serving and offers a unique, bold flavor.
Instant Coffee
Instant coffee is made by rehydrating freeze-dried coffee granules with hot water. Its caffeine content ranges from 30 to 90 milligrams per cup, depending on the brand, making it the mildest and quickest alternative to espresso.
| Alternative | Caffeine Content |
|---|---|
| Drip Coffee | 95 mg per 8 oz |
| French Press | 80–100 mg per 8 oz |
| Cold Brew | 150–200 mg per 8 oz |
| Americano | 63–125 mg per serving |
| Macchiato | 63 mg per shot |
| Cappuccino | 63–125 mg per serving |
| Turkish Coffee | 50–65 mg per 2 oz |
| Instant Coffee | 30–90 mg per cup |
By exploring these options, you can find a coffee style that suits your taste and caffeine preference, whether it’s the boldness of Turkish coffee or the smoothness of a cappuccino.
