The color of medium roasted coffee beans is between light brown and dark brown, and the oily sheen begins to appear on the surface. At this time, the taste of the coffee beans begins to show a sense of balance, with moderate acidity and bitterness, fruity aroma and a slight caramel flavor. The overall taste is rich and suitable for making a variety of daily coffee drinks.

3. Deep Baking

Deeply roasted coffee beans are dark brown to black with a noticeable oily surface. Coffee beans at this roasting degree have a strong bitterness, very low acidity, rich caramel flavor, and a mellow taste. However, it should be noted that over-roasting may cause the coffee beans to have a burnt smell and affect the taste. It is suitable for making coffee drinks such as espresso that emphasize a mellow taste.
