Roasting levels refer to the degree to which coffee beans are roasted, affecting their flavor, aroma, and color. The main levels include light, medium, and dark. Light roasts retain more of the bean's original flavors and acidity, while medium roasts balance sweetness and acidity. Dark roasts have a bold, rich flavor with less acidity, often featuring smoky or bitter notes. Each roasting level is achieved by controlling the temperature and time during the roasting process. Factors like the type of coffee bean and the desired flavor profile influence the choice of roasting level. Understanding these levels helps consumers select coffee that suits their taste preferences.
