02About

A koji house at the foot
of Munsusan

JANGAN FERMENT (장안발효) is a rice-koji processing specialist in Yul-ri, Cheongnyang-eup — the green-awning workshop by the Cheongnyang-Yul public parking lot at the mouth of the Munsusan trail.

Run by co-CEOs An Mi-jin and Jang Gu-hyeon, the team makes its own rice koji and builds every product on it: vegan rice and brown-rice yogurt, low-salt doenjang, eodoenjang, low-salt gochujang, eoganjang, salt nuruk and natural fermented seasonings, plus gift sets. Classes open with a tasting of the yogurt and the jang pantry before the doenjang-making session begins.
