Drive Mechanism
Multiple machine designs have been created to produce espresso. Several machines share some common elements.
Varying the fineness of the grind, the amount of pressure used to tamp the grinds, or the pressure itself can be used to vary the taste of the espresso. Some baristas pull espresso shots directly into a pre-heated demitasse cup or shot glass, to maintain a higher temperature of the espresso.
An espresso machine may also have a steam wand which is used to steam and froth liquids, to include milk, for beverages such as the cappuccino and latte.
