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.
Also in large scale machines there are options of keeping the water heated for a longer time and the coffee is constantly brewed so that the supply is almost instantaneous when switched on. However in small scale machines not much importance is given to the Commercial Coffee Maker heating and efficiency factors. The speed is also not much to talk about and hence the supply is done a long time after the switch is turned on as the brewing and heating starts again and again for every new cup of coffee. But all said and done the lapse in time due to reheating is hardly a minute or two making the wait a breeze when compared to other machines.
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.
There are several different kinds of single serve coffee machines on the market but I have a Keurig coffee machine. For the Keurigs coffee machines there are over 250 different kinds of coffee to choose from. They call their pod a K-cup. K-cups come in the caffeinated and non-caffeinated versions as well. So you are essentially able to brew a gourmet-style cup of coffee in the comfort of your own home at any time of the day.
