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.
If you are considering purchasing a new coffee maker for yourself, the single serve coffee makers like the Keurig would be an excellent choice. You will give yourself and others the freedom to pick and choose different kinds of coffee from cup to cup, and you are able to make it fresh every time. Save yourself some time and money and consider a single serve coffee machine for your next coffee maker.
Another advantage of this type of brewer is that everyone can brew the kind of coffee that they like. If someone in the house is a bold coffee drinker and another likes a milder type, they are not stuck drinking something that wasnt their choice. I have family gatherings at my home regularly, and coffee after dinner is commonplace. Everyone is very pleased with the fact that they can choose whatever they would like for their coffee.
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.
