Espresso vs coffee: which has more caffeine?
A shot of espresso has about 63 mg; a mug of drip coffee about 95 mg. The per-ounce truth is the opposite. See why.

Per serving, drip coffee has more. Per ounce, espresso is far stronger. A single shot has about 63 mg; an 8 oz drip coffee about 95 mg. But espresso is about 63 mg per ounce against about 11.9 mg.
| Drink | Serving | Caffeine | Per ounce |
|---|---|---|---|
| Espresso | 1 oz | 63 mg | 63 mg/oz |
| Brewed coffee | 8 oz | 95 mg | 11.9 mg/oz |
The classic trap
Espresso tastes stronger and is more concentrated, but the cup is tiny. A double shot latte lands above a small drip; a single shot lands below it.
