Flavor: Espresso has a bold, intense flavor that is often described as earthy, nutty, and chocolatey. It can also have hints of caramel, vanilla, and fruit flavors.
Aroma: Espresso has a rich, complex aroma that is both sweet and pungent. It is often described as having notes of roasted coffee, chocolate, and caramel.
Consistency: Espresso is thicker and more viscous than coffee brewed by other methods. This is due to the higher concentration of suspended and dissolved solids, and the crema on top.
Crema: Crema is the golden-colored foam that forms on top of a properly pulled shot of espresso. It is made up of extracted coffee oils and gases, and it adds to the coffee's rich flavor and mouthfeel.

Overall, espresso is a versatile and delicious coffee beverage that can be enjoyed on its own or used as the base for other coffee drinks.
