How Come An Espresso Shot Has Less Caffeine Than Your Regular Cup Of (Drip) Joe?

Espresso around 70. A cup of drip around 100. You need like a fistful of ground to make a single shot of E but barely a spoonful for a cup of brew. Ya’ll?

Maybe I missed it in the responses, but a shot of espresso is also far SMALLER than a cup of drip.

[By the numbers from the Mayo Clinic](https://www.mayoclinic.org/healthy-lifestyle/nutrition-and-healthy-eating/in-depth/caffeine/art-20049372), a cup of drip with 96mg of caffeine is 8 ounces, while the espresso (64mg in their chart) is 1 ounce.

To directly compare,

1 ounce espresso: 64 mg

1 ounce drip: 12 mg

8 ounces drip: 96 mg

8 ounces espresso: 512 mg
