Tea from Jeju Island

OSULLOC is a Korean tea brand born on Jeju Island. According to the brand, its story began in 1979, when Suh Sung-whan, founder of the Amorepacific group, started growing tea on Jeju at the Dolsongi tea farm. The first OSULLOC green teas came out in 1980.

The brand added the Seogwang tea farm in 1984 and the Hannam tea farm in 1995, and opened the OSULLOC Tea Museum on Jeju in 2001.

According to OSULLOC, its tea fields have held organic certifications, including USDA NOP and IFOAM, since 2010. Every tea on this page comes from the brand’s range made with Jeju-grown tea.

Sejak is a Korean grade of green tea made from young leaves. OSULLOC’s Sejak won Gold at the World Green Tea Contest in Shizuoka, Japan, in 2009 and 2014, according to the brand’s timeline. On our store it is listed as Sejack Green Tea and Sejac Tea.
