Kimchi origin: Korean history, culture and tradition

Kimchi origin : This iconic fermented condiment originated in Korea over 3,000 years ago, stemming from a tradition of preserving vegetables with salt and spices. A study published in the Journal of Ethnic Foods (2021) [1] estimates that kimchi is consumed daily by more than 95% of Korean households. Here are the key points to know:

• Kimchi has its first written records in Korean annals from the 1st century AD.
• Lactic fermentation is at the heart of its traditional preparation.
• Red chili pepper (gochugaru) was only added to the recipe in the 17th century.
• Kimjang, the ritual of collectively preparing kimchi, has been listed as UNESCO Intangible CulturalHeritage since 2013.
• More than 200 varieties of kimchi exist across the Korean peninsula.

Kimchi origin: 3,000 years of history in Korea

Kimchi's origins lie in the need to preserve vegetables during the long Korean winters. The first written records appear in the Samguk Sagi, a 12th-century compiling events dating back to the 1st century BC [2]. At that time, preservation was achieved solely with salt, without chili peppers.

Archaeological excavations confirm that Koreans practiced salting vegetables as early as the Three Kingdoms period. Cabbage, radish, and cucumbers were the most commonly used vegetables. This simple technique allowed them to maintain a consistent nutritional intake during the winter.

According toUNESCO [3], kimchi embodies a know-how passed down from generation to generation, making it much more than just a food: a vector of Korean cultural identity.

Before the chili pepper: the original form of kimchi

The earliest kimchi had nothing to do with the red, spicy dish we know today. For over 2,000 years, kimchi was simply cabbage or radish preserved in a salty brine, sometimes flavored with garlic or ginger. This type of white kimchi, called baek kimchi, still exists today.

Texts from the 13th century mention the addition of spices such as mustard and wild onions. Natural fermentation already produced probiotics, including lactic acid bacteria of the genus Lactobacillus. A study published in Food Microbiology (2020) [4] identified more than 700 strains of lactic acid bacteria in traditional kimchi preparations.

This rich microbial diversity partly explains why kimchi has endured through the centuries without losing its place in Korean cuisine. To learn more about fermented vegetables in general, see our guide on lacto-fermented vegetables.

The 17th century: the arrival of chili peppers transforms kimchi

The major turning point in the history of kimchi originated in the 17th centurywith the introduction of red chili peppers to Korea through Portuguese and Japanese trade. Gochugaru (dried red chili flakes) revolutionized the traditional recipe.

Before this date, no Korean text mentions chili peppers in the preparation of kimchi. After its introduction, chili peppers became an essential ingredient in less than a century. They provided not only flavor but also natural antimicrobial properties that improved preservation.

Food historians note that this rapid adoption demonstrates the adaptability of Korean cuisine. Kimchi, for example, has evolved from a staple food to a complex gastronomic element, rich in capsaicin and antioxidants.

Kimjang: the collective ritual at the heart of kimchi origin

Kimjang , and communities come together to prepare hundreds of kilograms of kimchi.

In December 2013, UNESCO inscribed kimjang on the Representative List of the Intangible Cultural Heritage of Humanity [3]. This recognition underlines that kimchi is not just a food, but a fundamental social bond in Korean society.

During kimjang, families prepare enough kimchi for the entire cold season. The quantities vary depending on the size of the household: a family of four prepares an average of 50 to 60 kilograms of kimchi during this annual session.

The founding ingredients of kimchi origin

The traditional kimchi recipe relies on a few essential ingredients, the selection of which reflects the geography and climate of the Korean peninsula. Here are the historically documented components:

• Chinese cabbage (baechu) : a staple vegetable since ancient Korean times.
• Sea salt : a primary preservative for 3,000 years.
• Garlic : used since the 9th century for its antimicrobial properties.
• Ginger : included for its flavour and digestive properties.
• Red chili pepper (gochugaru) : arrived in the 17th century via international trade.
• Fish sauce or fermented shrimp (jeotgal) : added for umami depth.
• Green onions : present in almost all regional varieties.

These ingredients work together to create an acidic environment conducive to lactic acid fermentation, naturally producing beneficial bacteria for the gut microbiota. Discover how these bacteria affect your health in our article on gut flora and probiotics.

The 200+ Varieties: Regional Diversity of Kimchi Origin

The original kimchi has given rise to remarkable diversity. Today, there are over 200 officially documented varieties, each reflecting local resources and regional preferences across the Korean peninsula.

The colder northern regions of Korea traditionally produce less spicy and more watery kimchi. Southern regions, such as Jeolla province, are known for their kimchi that is rich in spices and fermented fish sauce.

Kimchi origin: international recognition and globalization

Kimchi, of Korean origin, crossed national borders during the 20th century, first brought by the Korean diaspora, then adopted by lovers of Asian cuisine worldwide. Today, kimchi is sold in more than 80 countries.

South Korea exports more than 40,000 tons of kimchi annually, according to data from the Korea Agro-Fisheries and Food Trade Corporation (2022). The United States, Japan, and Australia are among the main importing markets.

This growing popularity is partly explained by the increasing scientific interest in fermented foods. A meta-analysis published in Nutrients (2021) [5] confirmed that regular kimchi consumption is associated with improved gut microbiota diversity.

The Korea-China controversy over the origin of kimchi

The question of kimchi's origin has been the subject of a notable diplomatic controversy between South Korea and China. In November 2020 , China submitted a request to the ISO for recognition of its own fermented cabbage, pao cai , which South Korea interpreted as an attempt at cultural appropriation.

The Korean government responded by strengthening the historical documentation of kimchi's origins, emphasizing that Korean fermentation practices are distinct from Chinese techniques. UNESCO maintained its recognition of kimjang as Korean heritage.

This controversy has paradoxically increased the global visibility of kimchi and its history. Many readers have told us that this debate has led them to take a greater interest in Korean culinary culture and to try kimchi for the first time.

Lactic fermentation: the scientific mechanism behind the origin of kimchi

Original kimchi relies on a lactic fermentation . When the vegetables are salted, the water is extracted by osmosis, creating an anaerobic environment conducive to the development of lactic acid bacteria naturally present on the vegetables.

The main bacterial species involved in kimchi fermentation include:

• Leuconostoc mesenteroides : dominant at the beginning of fermentation.
• Lactobacillus plantarum : predominant in advanced fermentation.
• Lactobacillus sakei : contributes to preservation and flavor.
• Weissella koreensis : species specifically identified in kimchi.
• Lactobacillus brevis : producer of lactic acid and carbon dioxide.

This process produces lactic acid, which lowers the pH of kimchi to between 3.5 and 4.5, inhibiting the growth of pathogenic bacteria. It is this mechanism, discovered empirically millennia ago, that has ensured the food safety of kimchi throughout the centuries.

Kimchi origin and nutritional value: what science says

Kimchi, with its ancient origins, has produced a food whose nutritional value is now validated by modern research. Kimchi is naturally low in calories (approximately 15 to 30 kcal per 100 g) while being rich in essential nutrients.

Here's what 100 grams of traditional kimchi provides:

• Vitamin C : 18 to 22 mg (source of antioxidants).
• Vitamin K : 43 µg (important for blood clotting).
• Folates : 28 µg (essential for cell division).
• Dietary fiber : 2 to 3 g (promotes intestinal transit).
• Live probiotics : 1 to 2 billionCFU per gram.
• Capsaicin : active compound in chili peppers with anti-inflammatory properties.

An ANSES study on fermented foods ( 2022 ) [2] confirms that lacto-fermented vegetables such as kimchi contribute to intestinal microbial diversity, a key factor in overall health.

How to prepare kimchi according to the original tradition

Respecting the original kimchi in preparation involves following precise steps, passed down orally from generation to generation before being codified in Korean culinary texts such as the 17th -century Eumsik dimibang .

The fundamental steps in traditional preparation are:

1. Salting : cut the cabbage and massage it with sea salt for 2 to 4 hours.
2. Rinsing : Rinse thoroughly to remove excess salt.
3. Preparation of the seasoning paste : mix gochugaru, garlic, ginger, fish sauce.
4. Massage : Incorporate the paste evenly into the cabbage leaves.
5. Fermentation : place in airtight jars, let ferment for 1 to 5 days at room temperature.
6. Storage : Refrigerate to slow down fermentation and store for several weeks.

Traditionally, kimchi was stored in earthenware jars (onggi) buried in the ground to maintain a constant temperature. This ingenious technique allowed for slow and even fermentation. To recreate this recipe at home, see our guide on how to make homemade kimchi.

Kimchi originates in popular culture and world gastronomy

Kimchi, of Korean origin, has inspired a global wave of interest in fermented foods. From Michelin-starred chefs to food bloggers, kimchi has become a popular fusion ingredient in kitchens around the world.

In France, kimchi has been available in Asian grocery stores since the 1990s, but its popularity exploded after 2020, fueled by the K-pop wave and Korean dramas. French supermarkets now offer industrially produced kimchi, often pasteurized, which differs from traditional, fresh kimchi.

The distinction is important: pasteurized kimchi loses a large portion of its live bacteria, reducing its probiotic value. To fully benefit from the nutrients in traditionally made kimchi, it's best to choose unpasteurized kimchi, kept refrigerated. To find out where to buy it, read our guide, "What is Kimchi?"

Kimchi origin and microbiota: current scientific evidence

Modern research validates what Koreans have known empirically for millennia: the original kimchi produced a food exceptionally beneficial to the gut microbiota. A randomized clinical trial published in Cell (July 2021) [5] demonstrated that a diet rich in fermented foods, including kimchi, increases microbiome diversity and reduces markers of systemic inflammation.

Researchers observed an increase in 19 types of beneficial bacteria in participants who consumed fermented foods daily for 10 weeks. These results highlight the importance of kimchi in the context of modern nutrition.
