Espresso Coffee Machine

A coffee maker is an electric countertop appliance that brews hot coffee automatically. It consists of a hot plate, a carafe or glass coffee pot, filter basket, and water reservoir. A coffee maker is a very simple, low-tech, yet efficient machine. A heating element circles the hot plate at the bottom of the maker.In the most basic terms, an espresso machine works by using steam, pistons, or pumps to force hot water through the puck of coffee beans. The high pressure inside an espresso machine and the low water ratio to coffee give espresso its distinctive thick consistency.
