Abstract This study examined tea-life in Pungseok Seo Yu-gu’s Limwongyeongjeji, who was an outstanding Silhak scholar of the late Joseon. Seo Yugu was born in Gyeonghwasejok family, and after he passed the state exam, he gained the favor of King Jeongjo, as a publisher of various books at Gyujanggak. Owing to the ruin of his clan, Seo Yugu began writing during his 18 years’ exile, and he continued writing after he returned to the central government and was appointed to important posts. He published a large-scale work, Limwongyeongjeji, composed of 16 chapters, fully describing food, clothing, shelter, cultural life, and health care methods necessary for noblemen to live in the country district based on the interest in wide knowledge, which was a tradition of his clan. Seo Yu-gu had a tea life, cultivating a tea farm since he was young, and he was a tea master, who wrote about his tea life in his works, Ongheejabji and Geumhwagyeongdokgi. Limwongyeongjeji systematically included various and expert contents about tea, which were extracted from 144 books including Dagyeong. Currently, there are Dasan, Choui, and Chusa, who are known as masters of tea, and developed tea culture of the late Joseon. Unfortunately, it is regrettable that Seo Yu-gu , who cultivated tea trees and wrote more records of tea than them, is not included because he was young. Searching for the aspects of Seo Yugu as a tea master by considering the records related to tea included in Limwongyeongjeji makes us reflect on the trend considering that it was natural that there was no record and person related to tea of Joseon. Seo Yu-gu was a person who provided huge data for the prosperity of tea culture during the late Joseon, which was considered a declining phase of tea culture, and he is a person to be raised to a tea master who represented the late Joseon because he extended the prospect of tea culture during that time.
