They provide a balanced balance between human control and mechanised accuracy. Simple to use The top espresso machines are simple to use. The best espresso machines have an adjustable thermostat that keeps the water at a consistent temperature, as well as a pressure pump that increases the amount of water in each shot.

Traditional electric steam-driven espresso machines utilize an air-tight container to heat the water until it is at a boiling point, which releases the pressure in a shot of coffee. They are compact and cheap however they only allow 1 or 2 bar of pressure. This is less than the ideal 9 bar for espresso. Semi-automatic espresso machines work by introducing hot water through the portafilter, which is pre-ground and pre-tamped of beans. The barista handles the extraction process but has to manually measure the amount of beans, grind and tamp each cup of beans.
