Roasting Coffee Beans
Different coffee bean roasts are just as important to the flavor of your cup as the type of beans that went into your coffee. Overall, beans that are roasted lightly will be sharper and have a more acid overtone than heavily roasted beans. Dark beans are bolder and have a more fully developed flavor, though it is definitely possible to over-roast beans. They'll taste burned or smokey if they have been roasted for too long.
