Colombian coffee raw bean grading method

One: according to the defect rate

The number of defective beans allowed per 500 gr sample:

-Private raw bean exporter: 72 defects

-National Coffee Council: 42 defects

There are two kinds of defective beans:

-the first one: it's called a first-class flaw.

-the second kind is called secondary defect.

First: major defects (defects that affect the taste characteristics of coffee): black beans, moldy beans or sour beans

Private raw bean exporters: no more than 12 first-class defective beans

National Coffee Committee: no more than 8 first-class defective beans

Second: secondary defects (defects that affect the appearance of raw beans):

Discolored beans (old beans, over-dried beans, soybeans), broken beans, insect bite beans, shell beans, unripe beans, special-shaped beans

Private raw bean exporters: no more than 60 minor defective beans

National Coffee Committee: no more than 35 secondary defective beans

Note: the number of major defective beans can be replaced by the number of secondary defective beans, and one primary defective bean is equivalent to 10 secondary defective beans.
