How dark or light the coffee beans are. Darker coffee is your classic Italian beans and lighter coffee brings more flavours and complexity to the forefront.
How heavy or light the coffee tastes. Heavy is a deeper more coffee-like feeling, whereas light will hold more flavours and feel lighter in your mouth.
To get of sense of this brew two coffees, try a Press / PourOver with one spoon full and try it again with 3 and notice how it feels in your mouth.
How was the finish? Short, it disappeared too quickly and didn't sit in your mouth? Too Long a finish, the aftertaste it sat around and lingered for a little too long?
