Espresso is a concentrated form of coffee served in small, strong shots. It is made by forcing pressurized hot water through finely-ground coffee beans. This process results in a rich, aromatic brew with a layer of crema on top, which is a creamy foam that forms during the extraction process. Espresso serves as the base for many popular coffee drinks, such as lattes, cappuccinos, and macchiatos. It is known for its bold flavor and robust aroma, making it a favorite among coffee enthusiasts. Whether enjoyed on its own or as part of a larger beverage, espresso provides a quick and satisfying caffeine boost.
