Roasted Coffee Grading Test

Time: 15 Minutes
Passing Score: 100%

Like the green grading exam, here 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. It’s important to identify in the number of underdeveloped beans in a sample — 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.
