What is expresso shot?

Espresso shot is a highly concentrated form of coffee that is made by forcing hot water through a compacted puck of finely ground coffee beans. The result is a small, concentrated shot of coffee with a thick, creamy layer of foam on top, known as crema. Espresso shots typically contain about 1-2 ounces of coffee and are a popular base for a variety of coffee drinks, including lattes, cappuccinos, and macchiatos. The shot is known for its strong, bold flavor and caffeine content, making it a favorite among coffee lovers who crave a quick caffeine boost. It is also the foundation of many coffee drinks, as the strong flavor of the espresso can be complemented by other ingredients such as milk, syrups, and flavorings.
