Lightly roasted coffee beans retain more of the original flavor of the beans, usually showing higher acidity and stronger fruity aroma. Coffee beans of this roasting degree are suitable for consumers who like a fresh and delicate taste, especially for making drip coffee and cold brew coffee.

Medium roast is the most common roasting method. It enhances the sweetness and fullness of coffee while retaining the right amount of acidity.
