In 1938 Milan coffee bartender Achille Gaggia filed a Patent for a steam-free coffee machine. Unlike its predecessors Gaggias design used a revolutionary piston mechanism which forced water through the coffee grounds at high pressure. It was his quest for the perfect espresso in 1930s Milan that gave birth to one of Italys most iconic brands and heralded the production of the Espresso as we know it. Traditional Espresso Coffee Machines are the type you see in Café Nero Costa Coffee etc.
The special espresso coffee machines of the day are also capable of producing the special cappuccino latte and ordinary coffee drinks. These special coffee makers deliver rich and nearly syrupy espresso beverage as there is extraction and emulsifying of oils found in ground coffee. With usage of the superior espresso machines the ideal double shot of espresso should be taking only between 25 to 30 seconds to make ready the espresso drink from the time the pump of the coffee maker is turned on.
Other similar coffee machines use a tube in the center to pump the water to the top where it drops back down over the coffee grounds. They are coffee percolators and coffee urns and come in varying sizes. Urns have greater serving sizes that go as high as 60 cups for home use. Another coffee machine makes coffee by putting coffee in the bottom of a cylinder which is usually glass. A filter the size of the inside of the cylinder is then pressed down to the bottom producing the coffee. These coffee machines have names such as French press water press a press pot coffee press coffee plunger or cafetière.
One that is not as popular as all the others is the vacuum machine. They come in many shapes and sizes yet they are more alike than they are different. This system heats the water in the lower chamber creating a water vapor. This increases the pressure in the lower chamber and forces the water upward into the upper chamber that you add just before the water begins to rise. Brew for about 1.5 minutes then remove from heat the gases in the lower chamber cool and draws the brewed coffee downward via suction caused by a partial vacuum that ensures accurate extraction of oils and caffeine for a cleaner unit without the bitter taste.
