As an artist, baristas must monitor the quality of Italian espresso from the perspective of beauty. First of all, baristas must know how to judge the quality of coffee beans from their appearance. The coffee beans used to make espresso are roasted to a wide range.

Overbaked beans can make the bitter taste of espresso uncomfortable, like a mouthful of dirt.
