Espresso

Espresso is a concentrated coffee beverage that is brewed by forcing hot water through finely-ground coffee beans. It typically is pressurized. It's known for its strong and bold flavor, and is the basis for many different recipes. To make espresso, the barista uses an espresso machine, which pressurizes the water and forces it through the grounds. Espresso is often used as the base for various drinks like cappuccinos, lattes, and macchiatos. In the traditional preparation of espresso, a single shot (known as a "solo") utilizes 7 grams of finely ground espresso beans, resulting in approximately 30 milliliters of espresso, which is roughly equivalent to 1 fluid ounce.

Espresso is also used to describe a specific variety of coffee bean. Espresso beans are normally roasted to a medium to dark level. These beans are often a blend of different coffee varieties to achieve a well-balanced and flavorful shot of espresso. The distinction between espresso and regular coffee lies in their preparation methods, not the specific coffee beans used. Typically, espresso involves a lengthy roasting process (resulting in a dark roast), a fine grind, and the application of high pressure to produce a concentrated ounce or two of coffee.
