What is a characteristic of coffee brewed using the espresso method?

Coffee brewed using the espresso method is known for its rich and concentrated flavor. This brewing technique involves forcing hot water through finely-ground coffee under high pressure, which extracts a robust essence of the coffee grounds. As a result, espresso has a heavy body and a bold taste, often featuring complex flavor notes that can include sweetness, bitterness, and acidity all in a very concentrated form.

The espresso method also produces a small volume of coffee, typically served in shots, which enhances the perception of its flavor intensity. This characteristic is what distinguishes espresso from other brewing methods, which may produce a milder or more diluted beverage. The crema, a golden foam that forms on top of the espresso, contributes to both the flavor and visual appeal, further emphasizing its rich character.

In contrast, the low caffeine content option would misrepresent espresso, as it generally contains a higher amount of caffeine per ounce compared to regular brewed coffee. Smooth and light flavor suggests a different brewing method, such as pour-over or drip coffee, which typically yields a lighter body. The cold temperature doesn’t apply to espresso, as it is traditionally brewed and served hot. Thus, the defining characteristic of espresso is its rich and concentrated flavor, making it the correct choice.
