Flavor description of moderately roasted and deep-roasted coffee beans

Baking is roughly divided into shallow baking (Light), medium baking (Medium), urban baking (City) and deep baking (Deep). Light roasted coffee beans: will have a strong smell, very crisp, high acidity is the main flavor and slightly mellow. Medium-roasted coffee beans: have a strong mellow, but also retain a certain degree of acidity. City-baked coffee beans: the surface is dark brown, the acidity is replaced by slight bitterness, and most of the flavor has been destroyed. Deep-roasted coffee beans: dark brown in color and oily on the surface. For most coffee beans, the alcohol content increases significantly and the acidity decreases. In fact, roasting coffee is a way of processing food.

A series of chemical changes occur during the baking process. After about 5-25 minutes of baking (depending on the temperature selected), the green coffee beans lose some humidity and turn yellow. In this process, the coffee beans will swell, changing from a strong, high-density raw bean to a low-density fluffy state. After this process, the coffee beans will about double in size and begin to show a light brown after stir-frying. After this stage is completed (after about 8 minutes of baking), the calories will be reduced. The color of the coffee soon changed to dark. When the preset baking depth is reached, cold air can be used to cool the coffee beans in order to stop the baking process.
