Just like other types of tea, with the exception of herbal teas, black tea is made from the leaves of the tea plant Camellia sinensis. The leaves of black tea get their colour as a result of being fully oxidised, unlike green tea where the leaves remain green. The processing of black tea is similar to that of making other teas; the leaves are aerated, withered, rolled, and oxidised, sometimes in multiple repetitions. However, black tea undergoes particularly extensive oxidation, which endows it with its dark colour and characteristic flavour.
Black tea contains many valuable compounds such as antioxidants, vitamins, and minerals that give it many nutritious properties. Despite the growing popularity of other types of tea such as green and white tea, black tea still accounts for over 90% of all tea sold in the West. If you like black tea, you can consume it in various ways. People who enjoy drinking black tea often add milk and sugar. You can also add herbs or dried fruits to black tea to give it extra flavour.
