All Korean traditional nonalcoholic beverages are referred to as eumcheong or eumcheongnyu (음청류 飮淸類) which literally means "clear beverages". Eumcheongnyu can be divided into the following categories: tea, hwachae (fruit punch), sikhye (sweet rice drink), sujeonggwa (persimmon punch), tang (탕, boiled water), jang (장, fermented grain juice with a sour taste), suksu (숙수, beverage made of herbs), galsu (갈수, drink made of fruit extract, and Oriental medicine), honeyed water, juice and milk by their ingredient materials and preparation methods. Among the varieties, tea, hwachae, sikhye, and sujeonggwa are still widely favored and consumed; however, the others almost disappeared by the end of the 20th century.
