Oolong is neither a black tea nor a green tea; it falls into its own category of tea. Yet an oolong may end up with more black tea characteristics or more green tea characteristics depending on the direction the tea master takes in the processing of the tea.
Oolong represents a true artisan mastership of tea processing. The appearance, shape and flavor of an oolong tea can vary wildly depending on the region where it’s grown and how it’s processed. The origins of oolong are claimed in both China and Taiwan and the tea is still highly revered in both countries today.
