How do Espresso Machines Make Espresso Coffee
Espresso machines are devices specifically engineered to brew espresso coffee drinks. Espresso machines vary in price depending on the type and come in a variety of sizes with matching features. In the marketplace you will generally find five different types of espresso machines.
Manual Espresso Machines
Manual espresso machines require the user to manually initiate each process step of brewing an espresso coffee. Manual espresso machines host a lever that the user manually operates to apply pressure to water forcing it through the coffee grinds to produce a cup of coffee.

These machines include controls for manually starting and stopping the brew process and a pump for assisting in the brewing action. You must manually add coffee to the machines, tamp the coffee grinds in the portafilter and clean the machines when finished. Semi-automatic espresso machines do not contain a coffee grinder.
Automatic Espresso Machines
Automatic espresso machines are easy to operate and automate those steps performed manually in semi-automatic machines. These types of machines also feature a pump.
Most cafes use the automatic type of espresso machine for preparing espresso drinks. High volume cafes find the push-button operation convenient and fast, which is a big help in situations with constant customer flow.
Within a cafe setting, for example, the barista simply fills the portafilter with coffee grinds, tamps the grinds and uses the auto buttons to allow the machine to perform the espresso brewing stage. An automatic machine can produce one or more cups, depending on the settings. The machines are capable of producing both regular espresso and decaffeinated brew styles. The final cup of espresso is ready to drink within a few seconds. A knob or preset button controls the milk steamer. This gives the barista choices over the final espresso quality. The design features of automatic espresso machines ensure that brewing espresso coffee is fast, ideal for high volume demand purposes, easy to learn how to operate.
Steam Driven Espresso Machines
The oldest type of espresso machine, steam driven models use steam pressure and boiling water to create espresso and other coffee drinks. The models are inexpensive, brew a cup of espresso in about one minute and may or may not contain a pump to aid in sending water through the coffee grinds.
