They all start with the same shot
Espresso is the foundation of both drinks. It is a small, concentrated coffee made by forcing hot water through finely-ground coffee under pressure. A latte is espresso + lots of milk. A cappuccino is espresso + a little milk + lots of foam. Remove the milk from either and you are left with espresso.

So which is strongest?
In flavor, espresso is by far the strongest because it has no milk at all, followed by the cappuccino, then the latte. In caffeine, however, they are nearly identical when each uses one shot — around 64–68 mg. A bigger drink does not mean more caffeine; more shots do.
