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.
A wonderful traditional Italian concentrated coffee beverage is espresso. This is brewed by forcing hot water (195 degree Fahrenheit) at high pressure (90 bars) through special coffee ground to a consistency between extremely fine and powder. The appliances that are used to prepare the beverages are the espresso machines. The knowledge and efficiency in making the finest espressos is considered as a craft and the baristas who are adept in using the espresso machines professionally are regarded as skilled craftsmen in this light.
The traditional scenario for needing to find an office coffee machine is the obvious one of working in an office full of co-workers. In this type of situation, a one cup at a time machine could still work, but might not be optimal. If a high percentage of the people in the office are drinking coffee, it would be smart to invest in a maker with a large carafe. By brewing more coffee at a time, you improve the efficiency of the process. Some machines also feature hot water dispensers for hot water on demand. This is a great feature as it allows people in the office who enjoy hot tea or instant soup to get hot water when they need it without disrupting the production of coffee.
