Black tea, also known as red tea, is a type of tea that is more oxidized than green, oolong, and white teas. It is made from the leaves of the Camellia sinensis plant and is known for its rich flavor and bold color. The production process includes withering, rolling, oxidation, and firing. The leaves are rolled and oxidized until they turn dark and develop a strong aroma and taste. Black tea is often consumed with milk and sugar and is a popular beverage worldwide. It is also used in cooking and baking to add flavor and depth to dishes. Some popular types of black tea include Darjeeling, Assam, and Ceylon.
