Which type of coffee has a concentrated flavor due to brewing under pressure?

Espresso is characterized by its concentrated flavor, which is achieved through the brewing process that involves forcing hot water through finely-ground coffee at high pressure. This method not only extracts the rich flavors and oils from the coffee grounds but also creates a distinctive crema, a creamy, golden layer on top of the espresso shot. The pressure plays a crucial role in extracting more flavorful compounds in a shorter amount of time compared to other brewing methods, resulting in a bold and intense coffee experience.

Other methods, like cold brew, pour-over, and French press, do not utilize this high-pressure brewing technique and hence produce different flavor profiles and intensities. Cold brew typically has a smoother and less acidic taste due to its long steeping process in cold water. Pour-over emphasizes clarity of flavor but does so without pressure. The French press allows for full immersion, creating a different kind of richness but not the concentrated intensity that espresso achieves.
