Espresso is the traditional coffee of Italy. The first espresso machine was designed in Italy by Angelo Moriondo. He received a patent for his invention which he demonstrated during the Turin General Exposition in 1884. A mechanic in Italy, Luigi Bezzera, obtained a patent for the improvements he made to the machine in 1901. The founder of the La Pavoni company, Desiderio Pavoni, bought the patent in 1905. He then started making the machine for commercial purposes.
There are various kinds of espresso machines and many have different mechanics, but they all work using the same basic principles. A super-automatic espresso machine automatically takes care of grinding the beans, boiling the water, brewing the coffee, and the clean-up process. The operator just needs to load the bean hopper, and add water to the reservoir, unless the machine is set up with a water line. A number of models automatically froth the milk. Some believe that the quality of the espresso may be affected because there is no manual tamp.
These machines offer the ability to make different kinds of espresso drinks. A super-automatic espresso machine is easy to use but they are more expensive. These machines can cost anywhere from $500 to $3,000.
Just like semi-automatic machines, super-automatic machines have basic features such as a water reservoir, water pump, boiler, dials, switches, and also a steam wand. A super-automatic espresso machine is different from a semi-automatic one because they have a burr coffee grinder and an automated internal espresso brewing system. Super-automatics have a computer that makes sure each component works smoothly, consistently and effectively. These beneficial features eliminate uncertainty which some people experience when using a semi-automatic espresso maker.
The automated brew system of these espresso machines is called the “brew group.” This component carries out all of the essential functions that are required for brewing great tasting espresso. After each espresso shot, the machine’s brew group will automatically reset and prepare itself for the next shot.
Some models have extra features such as a grinder with settings, bypass dosers, dual heating elements, digital displays, programmed liquid volume control, cup warmer, and water filtration system. These additional features may give the user more control compared to using an automated espresso machine.
Commercial businesses usually use semi-automatic machines that have several group heads. These types are bigger than most consumer models. They are capable of making espresso shots faster. Many commercial espresso machines also have an automatic mode. Manual espresso machines are very popular in Europe because drinking straight espresso is very common there.
Most super-automatic espresso makers tend to be more compact compared to machines that have a separate grinder. Additionally, super-automatics can make the very popular café crème that is similar to espresso, yet not as strong. For many, the features of a super-automatic espresso machine not only add value, but also give espresso connoisseurs the ability to quickly make a delicious shot of espresso.
