Espresso Has Less Caffeine Than Regular Coffee

Espresso Has Less Caffeine Than Regular Coffee

Today I found out that an espresso actually contains less caffeine than a brewed (regular) coffee.

This would be due to the simple fact that when making an espresso, the water doesn't stay long enough in contact with the coffee and so the caffeine doesn't get trap in/by the water.
