A classic blend of coffee should possess the following characteristics:
* First, it should have a nice sustained crema. Mouthfeel is a huge part of the espresso experience.
* Second, there should be at least a hit of brightness to wake up the palate.
* Third, as the taste of your sip lingers in your mouth the body should become more apparent and provide that rich palate coating experience people love.
* Fourth, the shot should finish relatively cleanly and the aftertaste should be pleasurable.
