Coffee and Caffeine

Robusta coffee contains more caffeine than Arabica does.

There are about 65 mg of caffeine in an Arabica espresso. Our bodies are able to eliminate 50 mg per hour on average.

A Robusta espresso contains 180 mg of caffeine, meaning your body will take 4 times as long to get rid of the caffeine!

There's more caffeine in a filter coffee than an espresso, because the water stays in contact longer with the coffee grounds, meaning that more caffeine is extracted.
