What is the difference between a latte and a cappachino?

The differences between these drinks are subtle, but significant.

Think of a cappuccino as drinking espresso and a little steamed milk through a "cap" of tons of light, fluffy, shaving cream-style foam. The espresso and steamed milk are sitting on the bottom of the cup, while the huge "cap" of light, fluffy, shaving cream-style foam is on top.

A lattè is a blend of espresso and velvetized foam. A lattè is a little heavier in the hand than a cappuccino because the lattè does not have that huge "cap" of light, fluffy, shaving cream-style foam. Finally, a lattè is a little milder than a cappuccino due to the greater volume of steamed milk and velvetized foam.

Since this is one thing I do for a living, I think I can safely trump in here and say that a latte (meaning milk) has more milk than a cappuccino.

A cappuccino has more espresso than a latte. This is a guide I give my staff:
