1. The perfect espresso surface is covered with a rich red crema (dark brown coffee oil, containing key aroma molecules of coffee).

2. A good espresso will leave a rich fragrance in the cup after drinking it.

3. Observe the degree of crema hanging cup (remaining on the cup wall).

Hanging more cups is a good espresso. If there is no "hanging cup" abroad, you can refuse to pay the bill!
