If you work in a small office, a machine with a small carafe is sufficient. However, you work in a very large office, a machine that can fill a large coffee urn might be what is needed. Another feature that would be useful in this type of environment is a machine with a "time to clean" indicator coupled with a self clean feature. Often, calcium buildup can occur in these machines and an indicator of when the machine needs to be cleaned is important. In a shared environment, it is very likely that responsibilities like cleaning the coffee machine can be ignored due to the phenomenon known as the tragedy of the commons. By having a machine with simplified cleaning measures like an auto-clean, you can avoid the pitfall of nobody taking responsibility to clean.
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.
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.

Been brave enough for months bearing all those long lines on the counter, finally hearing your name and off you go with your hot concoction?
