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.
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.
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.
