Classification of Green Coffee Beans: Brazil / New York Method

Grading Coffee Beans in Brazil

In the Brazilian method 300 grams of coffee is classified.  The number of coffee beans equivalent to one full defect is given below.  For example, a set of three shells counts as one full defect.  On the other hand, one large rock counts as five full defects.  If a coffee bean has more than one defect, the highest defect is counted.  For example, a bean that is black and damaged by insects counts as one full defect due to its black attribute. Generally, coffee beans without defects, of the same origin, and that are similar in size, color, and shape, are classified as specialty green coffee beans.

The coffee beans classification table is split up into two, since Brazilian legislation allows a maximum of 1% of foreign defects.  After counting the number of defects, use the third chart is used to classify the type and its point rating.
