Espresso is a favorite for coffee lovers, prized for its bold flavor and quick energy boost. But how much caffeine is in a single shot of espresso? In this guide, we break down the caffeine content, what affects it, and how it compares to other coffee drinks.
Caffeine Content in a Single Shot
A single shot of espresso is about one ounce. It typically contains 63 milligrams of caffeine. This is more concentrated than regular coffee. However, the serving size is much smaller.
What About a Double Shot?
A double shot of espresso is called a “doppio.” It contains approximately 125 milligrams of caffeine. This is the standard amount used in many coffee drinks. Examples include lattes, cappuccinos and Americanos.
Factors That Affect Caffeine in Espresso
The amount of caffeine in espresso can vary. Several factors influence this:
- Type of Coffee Beans: Robusta beans have more caffeine than Arabica.
- Roast Level: Lighter roasts often have slightly more caffeine than darker ones.
- Brewing Time: A longer extraction time can result in higher caffeine content.
- Grind Size: Finer grinds may increase caffeine concentration.
Espresso vs. Regular Coffee
Espresso is more concentrated in caffeine. However, a full cup of regular coffee has more caffeine overall.
- Espresso (1 oz): 63 milligrams
- Regular Coffee (8 oz): 95 milligrams
If you need more caffeine, an entire cup of coffee may be the better choice.

- Boosts Energy: Provides a quick burst of alertness.

- Rich in Antioxidants: Supports overall health by fighting free radicals.
Potential Side Effects

- If you’re new to espresso, start with a single shot.
The most common misconception about espresso is that it is the “strongest” coffee option available. While it is true that espresso has the highest concentration of caffeine per ounce (roughly 63mg), the way we consume it changes its impact. A standard 8oz cup of drip coffee actually delivers more total caffeine than a single espresso shot because of the sheer volume of liquid. However, because espresso is a small, intense “hit,” the caffeine is often absorbed more rapidly by the body, leading to a quicker spike in alertness. This makes espresso the ideal choice for a precise, “surgical” energy boost when you need focus immediately, whereas a larger cup of brewed coffee is better suited for a slow, sustained caffeine release throughout a long morning.
