The leaves of green and semi fermented teas are usually whole and the grade is not specified. The same applies for a few of the black teas, particularly Chinese, where its name is a synonym of quality. For other black teas the grade is important since it gives two pieces of information:
- the fineness of the crop
- the size of the leaf (whole, broken, ground).
In these grading the term "orange" is not connected with the fruit of the same name. It means "royal", and comes from the name of the Dutch dynasty Orange Nassau. As for the word Pekoe it comes, as you will remember, from the Chinese word
Pak-ho meaning "fine hair" or "down", and denotes the end bud, which gives an impression of white down, since it is not entirely open.
