Fermentation & Preservation

Kimjang

Also: kimchang, gimjang, 김장

The Korean communal autumn tradition of making and sharing large quantities of kimchi to last through winter.

/GEEM-jang/Korean: 김장 (gimjang); the character 김 (gim/kim) relates to kimchi, and 장 (jang) denotes the season or act of preparation. The practice dates to the Three Kingdoms period (57 BCE–668 CE), though the modern gochugaru-spiced kimchi form only emerged after chili peppers arrived in Korea in the late sixteenth century via Japan.

Definition

Kimjang (김장; also romanized as gimjang) is the Korean practice—and the season—of collective kimchi-making in late autumn, typically between November and early December when napa cabbage (baechu) has sweetened with cold nights and the temperature is right for slow fermentation. It is one of the most significant food-preservation events in Korean culture and has been inscribed on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity since 2013. Historically, kimjang was a community survival event: households lacked refrigeration and needed to produce enough kimchi—often hundreds of heads of cabbage—to feed a family through the long Korean winter. Neighbors, extended family, and villagers convened to salt, rinse, and dress cabbages together over one or more days, sharing labor and ingredients. The social dimension is inseparable from the culinary one: kimjang reinforces communal bonds, passes down regional recipes and technique from elders to younger generations, and serves as a marker of the agricultural calendar. Modern kimjang takes place in apartment courtyards, church halls, community centers, and kitchen co-ops; corporate kimjang events are common in workplaces. The varieties made during kimjang are not limited to baechu kimchi—radish kimchi (kkakdugi), cubed radish (깍두기), water kimchi (mul kimchi), and wrapped kimchi (bossam kimchi) are all commonly prepared. Seasoning paste—made from gochugaru (Korean red pepper flakes), fermented salted shrimp (saeujeot), fish sauce, garlic, and ginger—is mixed in large communal batches. Finished kimchi is packed into onggi (earthenware crocks) or, today, dedicated kimchi refrigerators that hold the ferment at near-ideal temperature.

In use

“Every November, three generations of the family spent a weekend together for kimjang, salting sixty heads of baechu cabbage and rubbing each leaf with the deep-red seasoning paste.”

Notes

Scale of production

A single kimjang session for a family of four might process 30–100 heads of napa cabbage (30–100 kg), yielding enough kimchi for four to six months. Larger extended-family gatherings can process several hundred kilograms in a single day.

North and South regional variation

Northern Korean kimchi (and by extension North Korean style) tends to be less spicy and less salted, as milder winters allowed slower, gentler fermentation; southern kimchi uses more gochugaru, garlic, and fish-sauce, producing a spicier, more pungent result that ferments faster and stores well in warmer climates.

UNESCO recognition

Korea's 2013 UNESCO inscription emphasized kimjang as a living cultural practice of community solidarity and intergenerational transmission, not merely a culinary technique. The recognition has spurred government and local NGO programs to revitalize urban kimjang participation.
