Tea

Darye, Korean tea ceremony

Tea in Korea dates back over 2000 years.[14] It was part of a number of worship recipes, hoping that the good scents would reach the heavenly gods. Tea was introduced in Korea, when Buddhism was introduced from China, and later gave rise to the Korean tea ceremony, of which Korea has over 3000.

Originally tea was used for ceremonial purposes or as part of traditional herbal medicine. Green tea, as it is used in China and Japan, is not the only kind of tea drunk in Korea. A great number of teas made of fruits, leaves, seeds or roots are enjoyed. Five tastes of tea are distinguished in Korea: sweet, sour, salty, bitter, and pungent.
