Espresso doesn't just have a high concentration of caffeine, it also has a high concentration of every other part of the coffee bean.

    It has less caffeine because it extracts quickly under pressure. Strength = flavor

    Yup. That said, espresso also uses more coffee per amount of liquid, and the amount of caffeine is basically a function of the amount of coffee and how long it's in contact with the water.
