The Korean tea ceremony or darye is a traditional form of tea ceremony practiced in Korea. Darye literally refers to "etiquette for tea" or "day tea rite" and has been kept among Korean people for a few thousand years. The chief element of the Korean tea ceremony is the ease and naturalness of enjoying tea within an easy formal setting.
In 1981 Chae Won-hwa launched what became the Panyaro Institute for the Promotion of the Way of Tea, and by November 1995 she had established a formal graduation ceremony for those who had completed the full course of study. Such ceremonies are now held each year.
