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.

A shot of espresso in a small cup

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.

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.
