The drip coffee machines are usually electric ones that heat the water and then pump it over the grounds. However a stove top type is still used. The water is boiled in a tea kettle and poured into a top reservoir with holes in it. A smaller container below holds the coffee grounds usually with a filter. When the water finishes dripping through to the bottom the coffee is ready to drink. Both the electric and stove top makers come in many brands and in a wide range of prices. The less expensive ones require a filter while others may come with a permanent gold-coated coffee filter or other permanent filter.
Bean to cup coffee machines are relatively recent additions to the coffee machine market. The principle is to be able to duplicate more or less the range of espresso based coffees that are normally handmade on an espresso machine. All at the "Touch of a Button". As previously explained when using an espresso machine a Barista would make coffees by hand. Although not a long process it doesnt allow the Barista to prepare other food orders for example. In fast food outlets where staff do not have time to hand make a coffee or where there is limited staff training a bean to cup machine is the ideal solution. Bean to Cup machines are found in many self-serve environments such as Cafeterias Company Canteens. Bean to Cup machines are becoming popular in Offices.
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.
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.
