What Coffee Has the Most Caffeine?

Many people assume espresso contains the most caffeine. The answer is more complicated than that.

Caffeine Depends On

The total caffeine in your cup depends on bean type, roast level, brew method, and serving size.

Brewed Coffee vs Espresso

Per ounce, espresso wins. But per serving, drip coffee often contains more total caffeine because the serving size is much larger.

Final Thought

The strongest coffee isn’t always what you think. Understanding serving size matters just as much as brew method.
