The
espresso machine use steam to force the water
through the grounds instead of a pump and only generate about 3
atmospheres or bars of pressure. They also heat the water too much which
scalds the coffee.
History of Espresso Maker
- Espresso coffee was discovered by a goat herder who noticed that
goats had an extreme boost of energy after they consume red berry
growing from shrubs.
- A tired, hungry traveler witnessed this and he tried eating the
same red berry and found he was boosted with energy. He then
developed the espresso coffee.
- The first espresso coffee maker is said to have originated in
Italy in 1901 by Italian manufacturing company owned by Lugia
Bezzer.
- He introduced while he was simply looking for a way to help speed
up his employee's coffee breaks.
- He figured out that if pressure was applied in the brewing
process, the drink could be made in a lot less time.
Types of Espresso Maker
There are basically five types of espresso machines that can be grouped
into the following categories:
- Manual Espresso Maker : This machine uses a
lever that is operated manually to force the water through the
grounds. It allows the user to have a greater control over how the
espresso is made.
- Semi-Automatic Espresso Maker : This machine
allows addition of coffee manually and then the pump starts and
stops when the user pushes the brew button.
- Full Automatic Espresso Maker : This machine is
operated electrically and the user presses a switch and the machine
automatically functions.
- Super-Automatic Espresso Maker : This machine
is operated electrically and automatically grinds the espresso
beans, tamps it into a puck, doses the proper amount of water and
discards the puck into an internal dump box.
The Espresso Coffee Makers can also be classified as:
- Stovetop Espresso Maker : It is also known as
macchinetta. It works by heating water to create pressure, the
pressure then forces the water quickly through the coffee grounds,
resulting in espresso coffee.
- Countertop Espresso Maker : These brew coffee
by various methods.
The most common methods used are:
- Steam Method : The inside of the machine is
pressurized with steam needed to force water through the coffee
grounds.
- Pump Method : This will pump water
automatically into a tank to build up enough pressure to force water
through the grounds.
- Piston Style Method : This is an ideal method
for brewing coffee. This machine uses manual force to store up the
pressure needed to force water through the coffee grounds. The
machine works manually by the use of a lever connected to a spring
loaded piston.
