Chinese tea can be classified into five distinctive categories: white, green, oolong, black and post-fermented. Others add categories for scented and compressed teas. All of these come from varieties of the Camellia sinensis plant. Tea is an important part of Chinese tradition while tea consumption has remained a practice of daily life. The history of Chinese tea is a long and gradual story of refinement. Generations of growers and producers have perfected the Chinese way of manufacturing tea, and its many unique regional variations.
