Vietnam has different ways to describe the quality of coffee:
Grade 1, 2 en 3 are quality descriptions based on imperfections.
Screen 13,14,16 en 18 are ways to grade/describe bean size.
– Polished: Wet Polished (shortened as WP) is a way to rid the coffee bean of its skin, which improves the appearance and the flavor.
