Readers would like to ask about the baking of fine beans. After baking, we will first judge from the appearance of beans. The size of fine beans should not be too different, and there should be no unbaked beans among them. After that, it is necessary to judge from the aroma, acidity, texture and so on after brewing.

Distinguish between fine beans and fine coffee through sensory identification, just like wine tasters, judged by their professionally trained sense of smell, taste and vision. In fact, it is not easy for ordinary consumers to judge, but they can look from the appearance to see if there are defective beans, and then drink to see how the taste can be used as their own reference.
