How does espresso differ from brewed coffee?

Espresso is distinct from brewed coffee primarily due to the method of preparation and the grind of the coffee beans. It is made by forcing hot water through finely-ground coffee under high pressure, which results in a concentrated shot of coffee with a rich flavor and creamy body. The finer grind of the coffee beans is crucial for this process, as it allows for optimal extraction of the coffee's oils and flavors during the quick brewing time.

In contrast, brewed coffee typically involves a coarser grind and is made using methods that do not apply pressure, such as drip brewing or French press. These methods take longer for the water to extract flavors from the coffee grounds. The difference in time and technique results in different flavor profiles and concentrations of the final beverage. Thus, the fact that espresso is made using pressure and a finer grind accurately captures the key factors that set it apart from brewed coffee.
