An espresso machine brews coffee by forcing pressurized water near boiling point through a "puck" of ground coffee and a filter in order to produce a thick, concentrated coffee called espresso. Multiple machine designs have been created to produce espresso. Several machines share some common elements, such as a grouphead and a portafilter. An espresso machine may also have a steam wand which is used to steam and froth liquids for coffee drinks such as cappuccino and caffè latte.

Espresso is a coffee-brewing method in which a small amount of nearly boiling water is forced under pressure through finely ground coffee beans.
