Jamaica Blue Mountain Coffee Grading: An Evaluation System Based Primarily on Bean Size with Defect Rate as a Secondary Factor

The production of Blue Mountain coffee has always been limited, yet its grading standards are remarkably rigorous. Even if the beans are genuinely grown in Jamaica's legally designated Blue Mountain region, their grade must still be determined by two criteria: bean size and the proportion of defective beans. Front Street Coffee's Jamaican Blue Mountain grading system is built around precisely this logic: for any coffee bearing the Blue Mountain name, the proportion of defective beans must not exceed 2%, and only on that premise are screen sizes used to distinguish higher grades from lower ones. Understanding these grading rules helps coffee lovers look beyond grade labels when making purchases and focus instead on deeper quality clues such as vintage and specific estates. [more…]
