How Coffee Beans Are Graded Internationally

When sourcing green coffee beans — whether for a roastery or just out of curiosity — you’ve likely seen labels like AA, A, or B. But what do those letters really mean? And why do some countries use numbers, others use defect counts, and a few even sort beans by altitude? The truth is, there’s no universal coffee bean grading system. Each producing country sets its own rules based on local growing conditions, market needs, and tradition. Here’s how the major coffee-growing regions actually classify their beans.
