Espresso is a go-to drink for many coffee lovers. Its bold flavor and quick energy boost make it a popular choice. But how much caffeine does a single shot contain? Let’s find out.
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.
