This article will systematically sort out the SCAA's defect classification rules and scoring requirements, explain in detail the causes of various defective beans and their impact on cupping flavor, and help enthusiasts develop a keen eye for identifying specialty coffee.

Those new to specialty coffee are often confused by labels such as G1 and AA on the packaging.

Geisha coffee, by contrast, is famous for Hacienda La Esmeralda's red, green, and blue label system. This article will systematically sort through these grading systems while taking a deeper look at the core differences in flavor and mouthfeel between Mandheling and Geisha, helping coffee lovers understand the logic of quality evaluation in specialty coffee more clearly.
