Oolong teaΒ defies a fixed definition. It is typically described as βpartially oxidized teaβ, which is not wrong, but itβs not a complete picture. The oxidation level does not distinguish it as oolong tea.
Itβs their similarly shared process of elaborate transformation (withering, shaking, pan-firing, rolling, drying, baking) that put these otherwise disparate group of teas under the same name.
Note that the proper pinyin spelling is βwulongβ tea, but it is more common in English to see it spelled βoolong" tea and they mean the same thing.
