Vanilla lacks a standardized grading system, but certain terminology is used in order to distinguish vanilla types, which are appearance and size. However, the quality of the vanilla beans is mostly dependent on the moisture content, which ranges from very dry levels of 15-20% to moist levels of 35-38%. Vanilla beans are established after the curing process, in which the ripe green vanilla pods are turned into the commonly known black color.
