1. Classification of coffee roasting degrees

The degree of roasting of coffee can be divided into light medium roasting, medium roasting, deep roasting, etc. Each degree of roasting will bring different characteristics to the coffee.

Light-medium roast : The surface of the coffee beans at this stage is light yellow to light brown, with a slight bean aroma. Coffee at this roasting level has a fresh taste, obvious acidity, and a strong aftertaste.

Medium roasted : Medium roasted coffee beans are darker in color and have a rich aroma. The taste of the coffee is balanced, with both sourness and sweetness, making it the choice of many coffee lovers.

Deep roasted : Deep roasted coffee beans are dark in color, have a glossy and full surface, and exude a rich caramel aroma. Coffee of this roasting degree has a distinct bitterness and a mellow taste, but low acidity.

2. The relationship between baking degree and quality

The impact of roasting degree on coffee quality is mainly reflected in flavor and preservation.

Flavor : Different types of coffee beans have different optimal roasting degrees. Over- or under-roasting will destroy the original flavor characteristics of the coffee beans. The right roasting degree can highlight the unique flavor of the coffee beans, such as the floral, fruity or chocolate aroma of certain producing areas.

Preservability : Moderate roasting helps preserve coffee beans for a long time. Deeply roasted coffee beans have a glossy and full surface, which can isolate air and moisture to a certain extent, thereby extending the shelf life.

3. The relationship between baking degree and taste

Taste is the most direct feeling that coffee gives people, and the degree of roasting has a crucial impact on the taste.

Stimulation : Light-medium roasted coffee has a higher acidity and a stronger stimulation, which is suitable for drinkers who like a refreshing taste. Dark-roasted coffee is mellower and less stimulating, which is suitable for moments when you need to relax.

Sweetness : As the degree of roasting increases, the starch and sugar in the coffee will undergo a Maillard reaction, producing more sweetness. Medium to dark roasted coffee is usually sweeter.

Body and taste balance : Deeply roasted coffee has a higher body and a mellower taste, while moderate roasting can balance the various flavors of the coffee and present a richer taste.

We can see that the degree of roasting of coffee not only affects the quality of coffee, but is also closely related to the taste.
