O'sulloc

O'sulloc traces to 1979, when Suh Sung-hwan — who also founded the wider AmorePacific Group — set out to revive Korean tea culture by developing tea fields on Jeju Island's volcanic soil, starting with the Dolsongi field before adding the Seogwang and Hannam estates. Seogwang, once barren land turned into an organic plantation, carries its own historical footnote as the exile home of the calligrapher Kim Jeong-hui; Hannam, in Seogwipo, runs both green and black tea production out of a modern factory built for roughly 646 tons of annual output. The company launched its Sulloc-Cha tea brand in 1980 and opened the O'sulloc Tea Museum on Jeju in 2001, letting visitors walk the tea fields and see production up close rather than encountering the brand only through packaged retail. O'sulloc's fields earned USDA National Organic Program and IFOAM organic certification in 2010, and the company has entered — and been recognized at — major international tea competitions in Beijing and Japan. O'sulloc became a wholly owned, independently structured AmorePacific subsidiary in 2020, decades after starting as one founder's attempt to rebuild a tea-growing tradition that had largely disappeared from Jeju.
