The sharp scent of spicy pepper flakes permeates the air at a kimchi factory in Incheon. Within, brined napa cabbage rests in large metal vats during the first step of a traditional method.

"It's now considered a world food originating in Korea, but this situation is absurd," notes a factory owner. "This market has been taken away from us."

The challenge stems from a widening trade imbalance. The country brings in a greater volume of kimchi than it sends abroad, with lower-cost Chinese-made products taking hold in the domestic market.

A Costly Difference

Chinese kimchi sells to restaurants at about 1,700 won per kilogram. However, domestically produced kimchi average about 3,600 won per kilogram—over twice the price.

From January to October this year, imports reached $159 million, almost entirely from China, while overseas sales amounted to $137 million.

A Cornerstone of Culture

Kimchi is a fundamental part of culinary tradition on the peninsula. Its definition covers far more than the fiery napa cabbage best known by international diners.

• There are over 150 recognised varieties, made with daikon, cucumbers, scallions and other vegetables.
• They are seasoned with mixtures of chilli powder, garlic, ginger and fermented seafood paste.
• The natural fermentation produces health-promoting probiotics, bolstering its status as a health food.

Shifting Habits

Historically, families prepared large quantities together during kimjang, a tradition designated by UNESCO. However, how Koreans consume kimchi are evolving.

Single-person households have more than tripled since 2000, now accounting for more than 36% of all households. Consequently, a declining number make kimchi at home.

Nowadays, it is more often eaten pre-packaged or while eating out, where it is provided complimentary with every meal. Charging for such a staple would be inconceivable.

The Producer's Plight

"If you avoid losses and stay afloat, that’s considered lucky," comments a producer. "For many of us over the past decade, we could not afford to upgrade in equipment."

An Emotional Staple

Market forces mean that cost, rather than provenance or method, is now the decisive factor.

One producer who has operated a business for 29 years canceled plans for expansion years ago as foreign kimchi became popular. "Is it right to use kimchi from abroad when this is a food that contains our people’s soul?" he says. "It's deeply saddening."

Additional Challenges

These difficulties are worsened by the changing climate, which is disrupting napa cabbage agriculture. Growing in summer has become harder in usual highland growing areas, causing market prices to sharply increase from one year to the next.

Government agencies and producers are working on hardier cabbage types and improved storage systems, but industry groups doubt whether such measures can offset the economic pressures.

Around three-quarters of South Korea’s kimchi manufacturers are micro-businesses with four or fewer employees, relying on handcrafted techniques that struggle to compete with industrial-scale production in China.

Seeking Solutions

The industry is trying to respond, though with few options.

• A voucher scheme offers restaurants a financial incentive to switch back to domestically produced kimchi.
• There are calls for increased scrutiny of declared import prices for kimchi.
• Government measures include origin labeling programs for restaurants, agricultural support for cabbage growers, and research to extend kimchi’s storage time for export.

A Matter of Taste

Ultimately, many are convinced that quality remains the local industry's best asset.

"Our kimchi has a distinct flavor," states an association head. "That cannot be replicated."
