How much caffeine is there in a shot of espresso versus a cup of regular coffee?

The answer to what has more caffeine really depends on your perspective: If you are looking at caffeine from a volume perspective, espresso has more - about 65 mg/1 oz. But if you are comparing regular coffee (6-8 oz), you are looking at about 200 m of caffeine.

In simple terms: In the morning, if you down a large coffee you will have consumed almost three times more caffeine than if you had thrown back a quick espresso.
