Let's understand the basic concept of coffee roasting. Coffee roasting refers to a series of physical and chemical changes that occur in coffee beans under high temperature. During this process, the color, aroma and taste of the coffee beans will change significantly. Different degrees of roasting control these changes to create unique coffee flavors.

Lightly roasted : The surface of lightly roasted coffee beans is light brown, and there is a slight oil oozing out of the surface of the beans. Coffee at this roasting level has a fresh taste, obvious acidity, rich fruity and floral aromas, and an overall refreshing taste. Lightly roasted coffee is suitable for coffee lovers who like sour and fresh taste.

Medium roasted : The color of medium roasted coffee beans is between light brown and dark brown, and oil begins to precipitate on the surface of the beans. Medium roasted coffee has a balanced taste, with both sourness and sweetness, and also shows some nutty and chocolate aroma. This degree of roasting is suitable for the majority of coffee lovers and can fully show the original flavor of the coffee beans.

Deep roasted : Deep roasted coffee beans are dark brown with a glossy and full surface. The acidity of coffee at this roasting level is greatly reduced, the bitterness is strong, the taste is mellow, and it has obvious caramel and chocolate aromas. Deep roasted coffee is suitable for coffee fans who like heavy flavors and rich tastes.

In addition to the three common roasting degrees mentioned above, there are some special roasting methods, such as very light roasting and burnt roasting. Very light roasted coffee beans are close to the color of the original beans, and the taste is almost similar to that of light roasting, but the fruity acidity is stronger; while burnt roasting is to roast the beans to the point of almost carbonization. This kind of coffee tastes extremely bitter and generally only appears in specific occasions or experimental tastings.
