Espresso is a brewing method. The espresso brewing method is a process of heated water under pressure that passes through ground espresso blended coffee. Espresso blended coffee is what the roaster’s interpretation of how the espresso should taste, look, feel, and look.
Look: The espresso should have a crema (micro bubbles) floating on the top. The crema should be thick & longstanding throughout the cup.
Taste: Should be sweet, chocolaty, with a touch of earthy notes and the oils should linger on your tongue for a moment or two.
Feel: Creamy with a touch of astringency.
