Espresso is a concentrated coffee beverage brewed by forcing near-boiling water under high pressure through finely ground coffee to draw a small, intense shot.
Roasted-coffee bitterness dominates, over medium acidity, a high aroma and a notably thick, viscous body.
Reached for when a drink needs concentrated coffee flavour, colour and body in a small volume, it works both as a full base measure and as a shaken accent; its viscous concentration means a little contributes disproportionate intensity, and it is best used promptly before crema and aroma dissipate.
Cold brew coffee is the closest stand-in, carrying comparable coffee intensity when diluted to suit, though it lacks crema, hot-extracted brightness and the emulsified body; filter coffee preserves roasted-coffee flavour and aroma for a supporting role but is weaker and higher in volume, and no non-espresso coffee reproduces the pressure-emulsified crema and viscosity.
Espresso is a small, concentrated, high-pressure extraction topped with crema; filter coffee is a larger, weaker gravity-drip extraction with no crema and a thinner body.
Water is driven at roughly 9 bars through a compacted bed of finely ground coffee, extracting a shot in about 20–30 seconds; a standard serving runs about 25–30 ml, with single, double and triple sizes using roughly 7, 14 and 21 grams of grounds. Carrying more suspended and dissolved solids than drip coffee, it has a thicker body and is topped by crema, a lighter foam of emulsified oils and carbon dioxide released under pressure.
Crema and aroma fade quickly after extraction, so it should be used promptly rather than held.
Espresso originated in Italy in the early 20th century, with the individual-serving machine developed there and sold commercially from 1905.
