The content of defective beans directly affects coffee quality and grade classification. Taking Brazil as an example, the local system uses a "deduction method," grading based on the number of defective beans per 300 grams of main beans. In addition, coffee usually requires hand sorting during processing, and only by fully mastering the types and characteristics of defective beans can they be effectively removed. So exactly how many types of defective beans are there? This article will use illustrated explanations to introduce ten common defective beans one by one, including shell beans, stones, moldy beans, fermented beans, dead beans, immature beans, shell beans, insect-damaged beans, black beans, and cocoa beans, explaining their causes, appearance characteristics, and negative effects on coffee flavor, laying the foundation for subsequent learning about defective bean selection.

Espresso is the foundation of the Italian coffee system, and it is also something that many coffee lovers both love and fear. It is extracted in a short time through high temperature and high pressure, and the golden, dense layer of Crema on its surface is its hallmark.
