How Much Caffeine in a Shot of Espresso?
A single shot of espresso contains around 63 milligrams of caffeine. See the video below for better understanding.
Single vs. Double Shot Espresso
Most cafes now serve double shots by default. So, if you order a latte or cappuccino, you’ll probably receive a double shot:
-> A single shot of caffeine (1 oz) contains approximately 63 mg, while a double shot (2 oz) contains approximately 125 mg.
Did you realize that the caffeine level in espresso can vary?
Here’s what influences it:
| Factor | Impact on Caffeine |
|---|---|
| Coffee bean type | Robusta contains roughly twice as much caffeine as Arabica |
| Roast level | Lighter roasts usually contain significantly more caffeine |
| Grind size | A finer grind leads to stronger extraction |
| Water temperature | Higher temperatures – more caffeine extracted |
| Machine pressure | The better the machine, the better the extraction |
So, while 63mg is the average, your espresso might include 50 to 80mg depending on how it is prepared.
Espresso Vs Coffee Vs Other Drinks
Now, for a fun comparison! How does espresso compare to other favourites?
| Drink | Serving Size | Caffeine Content |

| Energy Drink | 8 oz | ~80 mg |
