A coffee percolator can be referred to in a number of ways, including coffee maker, coffee urn, or even just simply percolator. Other synonyms include drip coffee maker, pour-over coffee maker, and espresso machine. Depending on the style and function of the brewing device, it may also be called a French press, Moka pot, or vacuum coffee maker. Some specialized percolators may be referred to as commercial coffee makers or industrial coffee machines. Regardless of the specific name, the goal of any percolator is to extract the rich flavors of coffee beans and produce a delicious, aromatic cup of coffee.
