Original black teas ( Darjeeling in India , Sri Lanka , China , Nepal , Japan ) and flavored black teas . Black tea , called red tea in China, is a fully oxidized tea, unlike green teas which are not oxidized, or oolong teas which are partially oxidized. This oxidation gives the tea its round, assertive taste as well as an infusion with colors oscillating between dark brown and yellow-orange.
Black tea is the most popular type of tea in the West, probably due to its strong flavor and long shelf life. The black tea category is diverse, including several popular varieties such as English Breakfast black teas , Darjeeling or Earl Gray .
The pronounced taste of its infusion, its amber color and its robustness do not prevent its wide variety of flavors. These depend on the quality of the product, its origin and its manufacturing process. The selection of the terminal leaves (bud, first and second leaves) and the season of picking define its basic classification.
