The aroma and flavor change with roasting

As the roasting process progresses, the sugars and proteins in the beans undergo chemical changes, bringing out aromas like caramel or chocolate, fruity acidity, and nutty flavors. Roasting is not a simple act of "toasting"; it is a delicate process in which the flavor can change dramatically with just a few seconds or a few degrees.
