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.
The French press also known as a press pot coffee press coffee plunger or cafetière is a brewing device popularized by the French. Its operation is simple and can produce a stronger pot of coffee than some other types of java makers. The press pot consists of a narrow cylindrical container usually made of glass or clear plastic equipped with a lid and a "plunger" also made of metal or plastic which fits tightly in the cylinder and which has a fine wire or nylon mesh acting as a filter which can be cleaned and reused.
