How do Espresso Machines Work
Espresso machines are purpose engineered and manufactured for brewing espresso coffee. The type, size, brand and feature list are determining factors in the price of an espresso machine. In the marketplace you will generally find five different types of espresso machines.
Manual Espresso Machines
The manual espresso machine requires the operator to manage each step of the espresso coffee brewing process. The machines feature a lever that is manually operated to force water through coffee grinds to brew a cup of espresso. Initially, coffee grinds are packed into the portafilter with a tamper then the portafilter is connected to the espresso machine to begin the manual lever action. Automatic and semi-automatic espresso machines feature a pump to help the brewing process, this is not the case with a manual machine. So the espresso brewing process demands some learning and training for the operator to achieve an ideal cup of espresso.
Potential espresso machine owners, who seek a more authentic espresso brewing experience can opt for buying a manual espresso machine. Manual machines are also useful for educating professional baristas because the trainee gets the opportinity to fully appreciate each stage of the brewing process and develops an deeper understanding of the complete brewing process.
Semi-Automatic Espresso Machines
Several manufactures produce semi-automatic espresso machines. These machines feature automatic controls to begin and stop the espresso making process and a pump to aid the brewing stage. 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
Easier to operate compared to the manual and semi-automatic machines, these machines create an espresso coffee drink with little interaction from the user.
Most cafes use the automatic type of espresso machine for making espresso drinks. High volume cafes find the push-button operation convenient and fast, which is a big help in situations with constant customer flow.
Using an automatic machine only requires the barista to add coffee grounds into the portafilter, push the auto buttons and wait for the machine to deliver the espresso coffee into the cup. Automatic machines have settings for one or more cups with outlets for both regular and decaffeinated espresso brew. The machine then delivers an espresso coffee in 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
Steam type espresso machines produce coffee by the use of high pressure steam and boiled water. This design is a older type of process for making espresso 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.
Super Automatic Espresso Machines
These super automatic machines are relatively expensive when compared to other types noted above. But for the price, the whole espresso coffee making process is fully automated. The process includes; gindng the beans to produce the appropriate grind for the portofilter; tamping the coffee grinds; managing water pressure and flow, and finally removing the used coffee grinds ready for the next brew cycle. Although these machines are high ticket items, the espresso making process is fully automated right to the final step of turing itself off.
