What is Espresso coffee?
Espresso (Italian) is a flavorful coffee beverage brewed by forcing hot water under high pressure through finely ground coffeeThe qualitative definition of espresso includes a viscous, honey-like consistency, a higher amount of dissolved solids than drip coffee per relative volume, and is served in small amounts known as single or double shots (occasionally triple or more shots may be ordered). Espresso is chemically complex and volatile, with many of its chemical components degrading from oxidation or loss of temperature. A distinguishing factor of properly brewed espresso is the presence of crema, a reddish-brown foam which floats on the surface of the espresso. It is composed of oils, proteins and sugars. Crema has elements of both emulsion and foam colloid.
