Korean Onggi Jar Stand (Jangdokdae): A Unique Symbol of Fermentation Culture Found Nowhere Else in the World
A Traditional Fermentation Space Filled with the Wisdom of Korean Nature, Family, and Daily Life
A jangdokdae—the outdoor platform where onggi jars are placed—is a traditional Korean space for storing fermented foods such as soy sauce, doenjang, and gochujang. It is a uniquely Korean cultural heritage that even China and Japan do not possess in the same form. This article introduces the jangdokdae to international readers by explaining its structure, history, regional characteristics, daily-life culture, fermentation science, and cultural value in a clear and comprehensive way.
Introduction: Jangdokdae, the Heart of Korean Flavor and Emotion
Dear readers, hello!
Today, I would like to introduce you to Korea’s unique and unparalleled tradition: the jangdokdae culture.
Let’s begin.
The jangdokdae is much more than a place to store fermented foods. It is a living heritage that reflects Korean daily life, lifestyle patterns, family culture, and the wisdom of an agricultural society. Korean soybean paste, soy sauce, and red pepper paste have been essential to the Korean table for thousands of years, and the jangdokdae has been the central space where their fermentation and aging took place.
Korea’s four distinct seasons influence the fermentation process, while the earthenware jars naturally regulate temperature, humidity, and ventilation. When combined with the placement of jars, sunlight direction, drainage conditions, and the meticulous care of homemakers, each household developed its own distinctive “jang taste.”
Although traditional jangdokdae spaces are gradually disappearing today, the global rediscovery of fermented foods as health-promoting meals has brought renewed attention to the jangdokdae. To many foreign visitors, it appears as a unique and even mysterious tradition—and an essential element of Korea’s fermentation culture.
1. Definition and Functions of the Jangdokdae
“Jangdokdae” literally means a raised platform in the yard designed to hold jars filled with fermented pastes and sauces. According to the National Institute of Korean Language, it is defined as “a platform of a certain height used to place jars that contain soy sauce, doenjang, gochujang, and similar condiments.”
The jangdokdae serves two primary purposes:
1) To preserve fermented foods in optimal condition
Placed facing east to maximize sunlight
Built with drainage layers to prevent moisture accumulation
Raised 20–30 cm above ground level for ventilation and dryness
Onggi jars release fermentation gases through microscopic pores
2) A cultural space containing family tradition, beliefs, and wishes
A place to pray for the family’s health, success, and safety
A location where clean water was offered for wishes and blessings
A spiritual site for household deities such as Seongju or Chilseong
Thus, the jangdokdae was not merely a kitchen facility—it was a symbolic world reflecting Korean values and everyday spirituality.
2. History of the Jangdokdae: From Ancient Tomb Murals to Modern Homes
The history of the jangdokdae is exceptionally long. Jars appearing in 4th-century murals found in the Anak Tombs of Hwanghae Province suggest that this culture has existed for at least 1,600 years.
During the Joseon Dynasty, managing jars was one of the most important responsibilities of housewives, and even the royal court had court ladies whose sole duty was to oversee the making and storage of sauces. Jang management was considered so crucial that people even said the rise and fall of a household could be predicted by the taste of its sauces.
When I was young, children in the neighborhood would sometimes break a jar lid while playing and would immediately get scolded by adults.
Back then, every Korean household living in a detached home opened its jars at the jangdokdae to take out various fermented condiments and side-dish bases.
Even today, although fewer in number, many detached houses still maintain a jangdokdae in some form.
3. Structure of the Jangdokdae: Wisdom for Scientific Fermentation
A jangdokdae is not merely a pile of stones. It is a carefully designed and scientifically structured space optimized for fermentation.
3.1 Ground Structure
A 20 cm layer of gravel and river stones for drainage
A flat foundation built with stone slabs or lime
Raised 20–30 cm above ground level to enhance sunlight exposure and airflow
Jar lids opened at dawn to allow fresh air circulation
Korean onggi jars have microscopic pores that naturally circulate air and release gases, a process impossible to reproduce with metal or glass containers. This is one of the secrets behind natural Korean fermentation.
4. Regional Names and Diverse Forms: A Wide Spectrum of Korean Culture
The jangdokdae varies in name and form across regions, reflecting Korea’s cultural diversity.
North Korea: Jangdokgeori
Central & Gyeongsang regions: Jangdokgan
Jeolla region: Janggwang (often enclosed with a low wall and gate)
Jeju Island: Janghanggup
Particularly in the Jeolla region, the jars were protected within a walled enclosure, reflecting the region’s reputation for culinary excellence.
4.1 Regional Jar Shapes
These variations developed in harmony with local geography, climate, and lifestyle.
5. Criteria for Selecting Onggi Jars: Key to Perfect Fermentation
Choosing a good jar was considered just as important as preparing the sauce itself.
A bundle of straw was burned inside the jar to check for leaks
A clear, resonant sound when tapped indicated high-quality craftsmanship
Artisans carved symbolic patterns such as bamboo, turtles, or dragons for good fortune
These details reveal the care, intention, and aesthetic sensibility embedded even in a single jar.
6. Jangdokdae and Korean Daily Culture
The jangdokdae was regarded as a sacred space under the care of the homemaker, and many household rituals and folk beliefs were centered around it.
6.1 Rituals Performed by Homemakers
Placing a bowl of clean water on the jangdokdae and making a wish
Praying before major events such as exams, childbirth, travel, or illness
Seeking peace, protection, and blessings for the family
6.2 Everyday Wisdom: Socks, Chili Peppers, Pine Twigs
Attaching a piece of sock cloth to repel centipedes and enhance sunlight
Using pine branches to honor ancestors and bless the fermentation
Hanging chili peppers and charcoal on straw ropes to ward off harmful spirits
These practices combine folk beliefs, scientific reasoning, and the heartfelt wishes of Korean homemakers.
7. Social Importance and Historical Records
Classical Korean texts such as Samguk Yusa and Goryeosa contain numerous stories about soybean paste and soy sauce saving people’s lives. Between the reigns of King Taejong and King Seongjong of Joseon—a period of about 65 years—there are at least eight records of soy sauce being used to rescue suffering citizens during famines.
These accounts show that fermented foods were not merely condiments; they were medicine, survival tools, and national assets.
8. Changes in Modern Society
After the 1990s, urbanization and apartment living led to the decline of the traditional jangdokdae. Today, most people buy mass-produced fermented sauces from factories, and only a small number of households maintain a traditional jangdokdae.
However, recently:
The value of natural fermentation
Eco-friendly food storage
The cultural charm of household-specific flavors
Rising global interest in healthy fermented foods
These factors have brought new attention to the jangdokdae and the traditional practice of making sauces. There is even discussion about nominating this tradition for UNESCO Intangible Cultural Heritage status.
9. Why the Jangdokdae Exists Only in Korea
China and Japan both have rich fermentation cultures, but neither has a system resembling the Korean jangdokdae.
Japan: Stores miso and soy sauce in wooden barrels
China: Uses ceramic containers but lacks an outdoor platform system
Southeast Asia: Climate conditions prevent similar large-scale jar fermentation traditions
Thus, Korean onggi and the jangdokdae form a uniquely Korean tradition shaped by climate, cuisine, and lifestyle.
Conclusion: Jangdokdae—A Cultural Heritage that the World Is Beginning to Notice
The jangdokdae is the root of Korean flavor and family history—a unique fermentation system where scientific principles and cultural values are harmoniously combined. Although it may seem to be fading, the global resurgence of interest in fermented foods has renewed recognition of its importance.
The Korean jangdokdae is not simply a cooking area.
It is a cultural heritage containing Korean identity, lifestyle, and the wisdom of living in harmony with nature.
If we continue to preserve and share this tradition with the world, the jangdokdae will remain a powerful cultural symbol for future generations.
Thank you for reading today. I look forward to sharing more stories with you soon.
