Because of using steam as pressure and there is not always enough steam to create strong pressure, it sometimes cannot make a full-flavored espresso. It can make one carafe at once (about four shots of espresso). Besides, you cannot open it in the middle of processing to add more water because it needs to keep water to be hot to create pressure.

#3. Lever/Piston espresso machine

It is a manual machine, using a lever or a piston to create pressure. You need to have strong hands to push the lever when making coffee.
