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 finely-ground coffee beans, resulting in a thicker consistency than regular coffee. The brewing process extracts the flavors and oils from the coffee beans, creating a rich and robust taste. Espresso is typically enjoyed on its own or used as a base for other beverages like lattes, cappuccinos, and macchiatos. It is known for its bold flavor and is often appreciated by coffee enthusiasts for its intensity and complexity.
