How to accurately determine the roasting degree of coffee beans?

The roasting degree of coffee beans is one of the important factors that affect the taste and flavor of coffee. Accurately judging the roasting degree of coffee beans is crucial for baristas and enthusiasts. Here are some common methods to help you better judge the roasting degree of coffee beans.

First of all, appearance is one of the most intuitive and commonly used methods to judge the degree of roasting. Lightly roasted coffee beans are usually light yellow or light brown, with a smooth surface and no oil; medium roasted coffee beans are medium brown with slight oil; and deep or full city (French RoaST) are dark black and have obvious oil coverage.

Secondly, smelling can also help us identify different degrees of roasting. Light roasting will give off floral, fruity and slightly malty aromas; medium to dark roasting will have richer and more complex chocolate, nutty and woody aromas; and the whole city may have a spicy and smoky smell.

In addition, the texture of the coffee beans can also provide some clues. Lightly roasted coffee beans are usually harder and denser; medium to dark roasts make the coffee beans more fragile and have a noticeable oily feel on the fingers; full roasts make the coffee beans very fragile and have a very obvious oily feel.

Finally, tasting is one of the most direct and effective ways to judge the degree of roasting of coffee beans. Light roasting usually has a prominent acidity, a refreshing taste, and a distinct fruity aroma; medium to deep roasting has a more balanced and rich taste, with prominent chocolate and nut flavors; full roasting may bring bitterness and heavy taste.

In summary, several methods can be used to accurately judge the roasting degree of coffee beans: observing the color, smelling the smell, checking the texture, and tasting the taste can all provide us with important clues about the roasting degree of coffee beans. Of course, these methods require experience and practice to improve accuracy, so it is recommended to try coffee beans of different roasting degrees and communicate and share experiences with others.
