Roasted Coffee Grading Test
Time: 15 Minutes
Passing Score: 100%
Like the green grading exam, you must correctly identify the number of defects in a roasted coffee sample. In roasted coffee, the defects are “Quakers” — underdeveloped beans that do not develop in roasting. Most underdeveloped coffee beans are under-ripe — or picked too early as green cherries. Identifying the number of underdeveloped beans in a sample is essential, particularly when sharing diagnostic information with coffee farmers.
Count the number of pale beans in a sample of 100g, then classify that sample as specialty coffee, premium, or commercial. The roasted coffee grading exam is also open book.
