Espresso (/ɛˈsprɛsoʊ/ (About this soundlisten), Italian: [eˈsprɛsso]) is a coffee-brewing method of Italian origin, in which a small amount of nearly boiling water (about 90 °C or 190 °F) is forced under 9–10 bars (900–1,000 kPa; 130–150 psi) of atmospheric pressure (expressed) through finely-ground coffee beans. Espresso coffee can be made with a wide variety of coffee beans and roast degrees.
