After the initial purchase of a single serve coffee machine which ranges in price from $85 to $190, the cost per cup of coffee is much less than that of a cup of coffee from a gourmet coffeehouse. The average cost per cup of coffee is anywhere from $0.65 to $1.25 with a Keurig coffee machine. Compare this to upwards of $5.00 per cup at a coffeehouse. You will save a lot of money with the single serve coffee brewer.
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.
There is a separate Grinder, which usually sits on top of a Knockout Drawer which is used for the spent coffee pucks. Although most Traditional Espresso Machines have automatic dosing these days, the coffee making process is by hand (Artisan). The coffee shot; single or double is prepared using the machine. The milk is foamed using the machine Steam Wand. The coffee is then put together to make any one of the most popular coffees. Cappuccino, Latte, Mocha and Macchiato etc. All of the preparation adds to the "Theatre" of the Coffee Culture. Customers have a higher perception of an "Artisan Coffee" and are willing to pay more. Training is required to ensure quality and consistency.
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.
