what is espresso

Espresso is a concentrated form of coffee served in small, strong shots and is the base for many coffee drinks. It is made by forcing pressurized hot water through very finely ground coffee beans using an espresso machine. The result is a liquid stronger than coffee topped with a "crema," a brown foam that forms when air bubbles combine with the soluble oils of fine-ground coffee and sits on top of a properly pulled shot of espresso. The crema adds to the rich flavor and lingering aftertaste of espresso. The main difference between espresso and regular coffee lies in the beans, the brewing methods, and the resulting texture and flavor. Espresso is brewed through high water pressure and finely ground espresso beans, while coffee is brewed at a slower pace with less pressure and lighter roasted beans. Espresso is especially loved in its home country of Italy, where it originated, and is the base for various popular coffee drinks such as lattes, cappuccinos, and Americanos.
