Good coffee beans are shiny and have a strong aroma without being mixed with peculiar smell. No matter what kind of coffee beans, freshness is an important factor affecting the quality.
When shopping, grab one or two coffee beans in your mouth and chew them with a crisp sound (indicating that the coffee is not damp) and the fragrance of the teeth and cheeks is the top grade, but it is best to squeeze it with your hands to feel whether it is solid, rather than buying crispy coffee.
