An Italian tradition is drinking espresso being brewed with an espresso machine. Growing up in an Italian family drinking espresso and cappuccino daily was the normal. When company came, out came the stove top espresso maker. Milk was steamed on the stove and temperature watched. Years later, out came the electric home espresso coffee machine that sat on the counter.
Did you know that the first Espresso Maker were built and patented in Turin, Italy in 1884 by Angelo Moriondo? It was the first espresso maker made. It was at the Turin General Exposition of 1884 as an instantaneous confection of coffee beverage.
Here are four variants that exist in making coffee in a home espresso machine; the drive mechanism along with the fineness of the grind, along with the varying, amount of pressure used to tamp the grinds, the heat of the water, and the type of espresso bean used. Also make sure the home espresso machines and a frothing wand to heat the milk to make the cappuccino or hot chocolate
Some Baristas service put espresso in preheated demitasse cups or shot glasses to keep the temperature hot. A few at home use espresso machines have a heating base to keep cups hot.
There are four drive mechanisms:
Piston-Driven Mechanism
The two types of lever machines: Manual you the operator directly to push the water through the grounds. Spring piston design you the operator work to tension a spring, which delivers pressure for the espresso. This type of lever driven machine was developed in Italy in 1945.
Steam-Driven Mechanism
This design is used as for low-cost consumer machines as it doesn't need to contain moving parts. The mechanism forces water through a common boiler by using steam or steam pressure through four heads so four cups of coffee can be made at the same time.
Pump-Driven
Pump-driven machines were a refinement of the piston- driven mechanism that commercial espresso bars use. Some high-end home machines or commercial machines are often attached directly to the plumbing or for home use directly in built-water reservoirs.
Air-Pump-Driven
This is the new type of espresso machines that has been manufactured. This type of machines use compressed air to force hot water through coffee grounds. The compressed air comes for either a hand-pimp with N20 or CO2 cartridges or an electric compressor. This is a much smaller and lighter than electric machines. Often they are hand-held and portable.
Automation
*Semi-automatic: uses a pump instead of a manual force to deliver water through grinds.The basket has 3-way valve that releases the brew into the cups
*Automatic: brew volume as needed. You still have to grind and tamper the coffee grinds.
*Super-automatic: Grinds coffees, tamps it, and extract the espresso shot and adds water to reservoir. They have automatic frothing of the milk and dispensing device. You don't have to tamp and grind coffee manually, which is not good because you have no control how it may affect the quality of the espresso.
I have enjoyed espresso coffee for years and have been searching for a good espresso machines. It has been a family tradition for years.
