How Much Caffeine is in a Shot of Espresso?
The average shot of espresso contains around 64 milligrams of caffeine. This might seem surprising, but it’s true! While espresso is a more concentrated form of coffee, the actual caffeine content per shot is generally less than that of a regular eight-ounce cup of coffee, which contains about 96 milligrams.
Understanding Coffee Beans and Caffeine
There aren’t special ‘espresso beans’ used to make espresso. Most coffee, including espresso, is made from either Arabica or Robusta beans.
Robusta beans have nearly twice the caffeine content as Arabica beans, which can influence how much caffeine ends up in your espresso shot.
Why Espresso Feels Stronger
The brewing method plays a crucial role in the caffeine content of espresso machines. Fine grounds and high pressure water extraction result in a highly concentrated coffee. While a single shot has about 64 milligrams of caffeine, the perception of its strength is due to the quick intake and rapid effect on your system.
Espresso vs. Brewed Coffee
| Drink | Size | Caffeine Content |
|---|---|---|
| Espresso (single shot) | 1 ounce | 64 mg |
| Brewed Coffee | 8 ounces | 96 mg |
This table shows that although espresso has a higher concentration of caffeine per ounce, a regular cup of coffee often contains more total caffeine.
Impact of Espresso-Based Drinks
Various espresso-based beverages have different caffeine levels mostly depending on the number of espresso shots used. For instance, a doppio (double shot) has about 128 milligrams.
Here’s a quick list of popular espresso-based drinks and their caffeine content:
- Single Shot Espresso: 75mg
- Double Espresso: 150mg
- Cappuccino, Latte, Macchiato: 75mg (short/tall), 150mg (grande/venti)
- Mocha: 90mg (short/tall), 175-180mg (grande/venti)
These values reflect the average caffeine content in coffee and can vary based on the specific coffee blend and preparation method.
Conclusion
So next time you’re debating between a cup of coffee or a shot of espresso, remember the actual caffeine content might be less than you think.
The concentrated nature of espresso and the quick consumption make it feel more potent, but milligram-for-milligram, coffee often wins the caffeine contest.
