The difference and taste analysis between medium and dark roasted coffee beans

Basic process and classification of coffee bean roasting

Roasting coffee beans is the process of heating raw beans to transform them into cooked beans with specific flavors and aromas. During the roasting process, coffee beans undergo a series of chemical reactions, including water evaporation, oil release, and sugar caramelization. These changes cause the color of coffee beans to change from the original green to brown, and the aroma and taste will gradually become richer.

According to the degree of roasting, coffee beans are mainly divided into light roasting, medium roasting and deep roasting. Medium roasting means that the coffee beans are moderately heated, which not only retains the original flavor of the beans, but also develops a rich aroma and taste. The beans usually show a medium dark brown color, with a distinct caramelized flavor and moderate acidity.
