Yes. Espresso is a type of coffee with a strong flavor that is brewed with hot water at 92 degrees Celsius and high pressure at 9 bar over finely ground coffee powder.

Because there is a light milk froth on top, don't stir it with a coffee spoon when you drink it, even if you want to add sugar, it's best to sprinkle it evenly on the surface layer of the milk froth, and find an angle to drink it directly, so that the coffee can still maintain a sense of hierarchy even after it has been in your mouth.

Three elements of a good espresso:

One, the perfect espresso, the surface will be covered with a layer of rich crimson crema (is the surface of the coffee on the dark brown foam, containing the key aroma molecules in the coffee);

On the second hand, a good espresso will remain in the cup after the cup of pure flavor;

Observation of Crema The degree of "hanging cup" (remaining on the wall of the cup). Hanging cup is a good espresso, in foreign countries, if there is no "hanging cup" is to refuse to pay the bill.
