Originally 'tea' in Korean meant an aromatic beverage prepared by pouring hot water over treated (but not fermented or oxidated) leaves of the Camellia Sinensis plant. However, nowadays 'tea' in Korea also means beverages from other sources. These are officially called 'replacement tea' (??ａ?????). Thus, Korean tea (Korean: ?? ) is a common name for a variety of herbal and plant infusion, including the leaves of the tea bush (Camellia sinensis). Like brews made from tea leaves, Korean tea is prepared by combining hot water with fruits, leaves, roots, or grains. The resulting drink is served hot or cold.
