Types of Espresso Machines
Espresso machines generally fall into three categories:
Super-automatic espresso machines
Semi-automatic espresso machines
Manual or lever espresso machines
A super-automatic machine does everything automatically -- the
grinding, the tamping, the brewing, and sometimes even the disposal of
the used grains are all done with the press of a button. They leave
maintenance and consistency out of the hands of the operator in order
to create ease and quality with every espresso shot. However, many
prefer to have some control in the tamping and brewing process. It is
considered an art form to produce the perfect espresso.
Semi- and fully-automatic espresso machines will control the pressure
required to brew electrically, but the grinding, the pulling of the
shot, and the tamping must all be done manually. The espresso is then
brewed with the push of a button. The machine will usually need to be
taken apart and cleaned manually. It is easy to use, and generally the
most affordable type, but will allow variance in quality as the
tamping and grinding will be inconsistent.
The manual or lever espresso machine is operated solely by hand,
except for the heating unit. The water is forced through the shot by
pumping a piston manually. This can be an aesthetically pleasing
machine made of chrome or copper finish, and the challenge and art
that goes into preparing a superb espresso using a manual machine is
oftentimes a source of great pride in baristas. The highest quality of
espresso can come from a manual machine, yet the wide opportunities
for variations in the process will lead to inconsistencies.
