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.
Percolators and urns are also different in appearance but make coffee the same way. Cold water is put in the bottom and heat is applied to the water. Once these makers are turned on the water begins to heat and be pumped up through a tube that ends above the coffee basket. Some makers wait for the water in the bottom to heat some before the perking process begins. When the perking has finished the coffee is ready to drink piping hot. Many feel this is real coffee as it is usually a stronger tasting coffee than other methods. The unseen differences are in the way the coffee maker is made. Does it have more plastic than others is it programmable or digital and how much does it cost. Other unseen differences are in warranties how the coffee will taste and the wattage it will use to make the coffee. Whether it is a single coffee maker a pod maker or a multi-cup coffee maker percolator urn or espresso machine they all make coffee but how well and for how long often remain the greatest unseen differences of all.
