The idea of a vacuum coffee maker is to heat water in the lower vessel of the brewer until the expansion forces the water through a narrow tube into an upper vessel that contains the coffee grounds. When the lower vessel has more or less emptied itself and enough time has elapsed the heat is removed and the resulting vacuum will draw the brewed beverage through a strainer back into the lower chamber from which it can be stored. The device must usually be taken apart to pour into a mug. An early variation of this principle is called balance siphon. This variation has the two chambers arranged side by side on a balance like device with a counterweight attached to the heated chamber.
French press makers require hot water from a separate source while a vacpot which is called a siphon brewer or vacuum brewed coffee uses hot or cold water depending how one wants to use it. Another that requires hot water may not be considered a coffee maker but the coffee dripper that has a filter in it and sits on your cup or mug does make coffee. The most common maker is a drip coffee maker. This is true whether it is a pour over where hot water is poured over the grounds or hot water is pumped up from a side source and allowed spray water over the grounds. These makers have two shapes of filters known as the cone and the basket shape that has more drip area. Some drip makers offer a low electric heated hot plate while others offer radiant heat. Drip makers come in closed sealed and open coffee dispensing. Closed and sealed dispensing systems often close off the flavor and aroma while the coffee is being made.
