Tea comes from the evergreen shrub called Camellia sinensis. There are two varietals: Camellia sinensis var. sinensis (Chinese tea) and Camellia sinensis var. assamica (Assam or Indian tea). All tea comes from this plant.
Thousands of tea estates around the world produce tea. Each estate masterfully crafts a unique tea all originating from the Camellia sinensis plant. It is the process for picking and drying that determines the type of tea; green, yellow, white, oolong, black, and pu-erh.
Processing white tea
White tea is the least processed of all teas. Only the unopened buds and young leaves covered in silver fuzz are used, and they are merely withered and dried. White tea produces a very light-colored infusion with a mild flavour. Its caffeine content is even lower than that of green tea and is considered to have a very high level of antioxidants. White tea is best consumed without any additives at all.
