How does the SCAA grading system work?
The SCAA (now SCA) grading system evaluates based on physical defects and sensory quality. A 350-gram sample is inspected for primary and secondary defects, and the coffee is then cupped to assign a score. To be classified as 'specialty grade,' the coffee must have zero primary defects and a score of 80 points or higher.

The Association (SCA) grading system is the global benchmark for defining what constitutes 'specialty' coffee. It provides a standardized language that allows everyone in the supply chain—from farmers and exporters to roasters and consumers—to communicate about quality with precision. The system is divided into two main components: physical grading and sensory evaluation.
Physical grading involves a meticulous inspection of a 350-gram sample of . The grader looks for specific defects, which are categorized as either primary or secondary. Primary defects, such as full black beans, sour beans, or foreign matter like stones, are the most severe and are strictly prohibited in specialty-grade coffee. Secondary defects, such as broken or insect-damaged beans, are also counted, and there is a very low tolerance for them. If a sample exceeds the allowed defect count, it is downgraded, regardless of how good it might taste.
Once the physical inspection is complete, the coffee undergoes sensory evaluation, or '.' This is a standardized tasting process where the coffee is brewed under specific conditions and evaluated by a trained Q-Grader. The grader scores the coffee on various attributes, including fragrance, aroma, flavor, acidity, body, balance, and uniformity. Each attribute is scored on a scale, and the final tally determines the coffee's total score.
To be officially classified as 'specialty grade,' a coffee must meet two criteria: it must have zero primary defects and a total score of 80 points or higher. Coffees scoring 80–84.99 are generally considered 'very good,' while those scoring 85–89.99 are 'excellent,' and those 90 and above are 'outstanding.' This scoring system is not just a number; it is a reflection of the care taken at every stage of production, from the farm to the processing station.
In practice, this system ensures that when you see the 'specialty' label, you are getting a product that has been vetted for quality. It rewards farmers who invest in better harvesting and processing techniques, as higher scores often translate to higher prices at auction. For the consumer, it provides a reliable way to navigate the vast world of coffee, helping you find beans that consistently deliver a high-quality, enjoyable experience in your cup.
