Kimjang Season in Korea | How Winter Kimchi Is Made and Where Visitors Can Join in 2026

By late October, Korean supermarkets start to change. Napa cabbage arrives by the box, chili flakes by the sack, salted shrimp by the bucket, and signs go up taking orders for pre-salted cabbage. This is the run-up to kimjang (김장), when households make a winter's supply of kimchi in one long, messy, sociable session.

This guide explains what kimjang is and when it happens, what goes into the classic cabbage kimchi, a small-batch method for home kitchens, the food-safety points that matter, and the events visitors can join in autumn 2026. Dates and prices are as of October 2026 and come from the organizers or news reports linked under Sources.

Key takeaways

Kimjang, the communal making and sharing of winter kimchi, has been on UNESCO's intangible heritage list since 2013. Home kimjang usually peaks in late November and December.
Confirmed 2026 events: Gwangju Kimchi Festival (October 23-25), Goesan Kimjang Festival (November 5-8, foreigners' session November 5) and Gwangju's Kimjang Daejeon (November 27-December 13).
At home, start with a small chopped batch: clean tools, the recipe's full salt, a short warm ferment, then the fridge.

1. What kimjang is, and why UNESCO listed it

Kimchi is a whole family of salted, seasoned and fermented vegetables. Kimjang is the event: relatives, neighbors or a whole community make a large quantity at once and split it so every household has enough for winter.

The 2013 UNESCO listing

In 2013 UNESCO added "Kimjang, making and sharing kimchi in the Republic of Korea" to its Representative List of the Intangible Cultural Heritage of Humanity. The listing honors the practice, not the dish. UNESCO's description stresses cooperation between families, the exchange of kimchi and ideas between households, and recipes passed down within families, typically from a mother-in-law to a new daughter-in-law.

A year-long cycle

According to UNESCO, preparation follows the calendar: seafood such as shrimp and anchovies is salted in spring, sea salt is bought in summer, and chilies are dried and ground in late summer. Late autumn is the kimjang itself. Seoul still shows that shopping rhythm. Mapo-gu's salted-shrimp festival, held October 16-18 this year, targeted kimjang shoppers and included a "Kimjang with Foreigners" event, SBS reported.

Kimchi even has its own date. Korea's Kimchi Industry Promotion Act, amended in 2020, names November 22 as Kimchi Day (김치의 날).

2. When kimjang happens

Families watch the forecast, as UNESCO notes, for a practical reason. Mild weather makes fresh kimchi sour too quickly, while a hard freeze can damage cabbage and radish before they are salted.

The temperature rule of thumb

The Korea Meteorological Administration has described the ideal time as when the daily low falls to 0°C (32°F) or below and the daily average stays at or under 4°C (39°F). In a 2007 release it put Seoul's best date around November 29 and Busan's around the end of December. The further south, the later the kimjang.

What that means for travelers

Between late October and mid-December you will likely see kimjang somewhere: cabbage piles at markets, tarps and red rubber gloves in apartment courtyards, charity kimjang events run by local governments. Festivals often come earlier than the home peak because they double as ingredient markets, which fits a fall trip. Our fall foliage guide covers the same weeks.

3. What goes into kimjang kimchi

Recipes change by region and family, and that variety is the point. Most kimjang tables still share a core list for cabbage kimchi (배추김치, baechu-kimchi):

Ingredient	Korean	Role
Napa cabbage	배추 (baechu)	The base; salting softens the leaves so they bend without snapping
Coarse sea salt	천일염 (cheonilyeom)	Brining; non-iodized salt is the usual advice
Korean radish	무 (mu)	Matchsticks in the filling; daikon works abroad
Chili flakes	고춧가루 (gochugaru)	Color and heat; buy coarse flakes labeled for kimchi
Garlic, ginger, green onion	마늘, 생강, 파	Aromatics; some families add mustard greens (갓, gat)
Salted seafood	젓갈 (jeotgal), e.g. 새우젓 (saeujeot)	Savory depth; salted shrimp and fish sauce are common
Glutinous rice paste	찹쌀풀 (chapssal-pul)	Helps the seasoning cling

Whole heads or chopped

Kimjang traditionally makes pogi-kimchi (포기김치): halved cabbages, salted and stuffed leaf by leaf. Mak-kimchi (막김치) chops the cabbage first. It looks plainer but salts far more evenly in a home kitchen, so the method below uses it.

4. A basic napa cabbage kimchi method

This is a shortened version of the tested mak-kimchi recipe from Colorado State University Extension (reviewed October 2025); see their page for full detail.

Ingredients

Two medium napa cabbages (6-8 lb, about 2.7-3.6 kg in total); 1½ cups coarse non-iodized salt and 1 gallon (about 3.8 L) of cold water; 2 Tbsp sweet rice flour cooked in ½ cup water; garlic to taste and about 3 slices of ginger; 1 cup Korean chili powder; half a Korean radish (1-1.5 lb); 10 green onions; optionally an Asian pear and 1 tsp fish sauce.

Step by step

Prep. Wash your hands, rinse the cabbage, trim damaged spots, quarter, core and chop into 2-inch (5 cm) pieces.
Salt. Dip the pieces briefly in ½ cup salt dissolved in the gallon of water, then discard the water. Massage in the remaining cup of salt and leave covered at room temperature for 3-6 hours; longer means saltier.
Rinse. Rinse 3-4 times in cold water and drain for at least 30 minutes.
Make the paste. Boil the rice flour in its water, cool, then stir in minced garlic, ginger and the chili powder.
Add vegetables. Mix in matchsticks of radish, green onion and pear, plus fish sauce. Wear gloves; chili stings.
Pack. Rub the paste through the cabbage and press it into a glass or food-safe plastic container about two-thirds full. CSU advises against metal containers and chipped earthenware.
Ferment, then chill. Close the lid loosely enough for gas to escape. Ferment 1-2 days at a steady 68°F (20°C), or 3-4 days in the fridge, until test strips read pH 4.6 or lower.

For a first batch, we would go light on garlic and fish sauce, taste after a day, and note what to change. Family recipes are built from that kind of adjustment.

5. Fermentation and storage: the safety notes

These points come from University of Georgia Extension's 2025 guide to safe home kimchi and the CSU recipe.

During fermentation

Sanitize tools. UGA suggests washing equipment, then holding it in water of at least 160°F (71°C) for 30 seconds.
Keep the recipe's salt. Early on, salt is what holds harmful bacteria back until lactic acid bacteria take over. Cutting it sharply is not a safe shortcut.
Do not leave it out long. After the first day or two at room temperature, refrigerate at 41°F (5°C) or below.

Storage and when to discard

Keep kimchi pressed under its liquid and covered. It keeps souring; CSU says quality is best within about two weeks, and very sour kimchi is classic for stews and pancakes. Throw out any batch with mold, an off smell unlike normal sourness, or an unusual texture. UGA treats these as safety warnings, not just quality issues.

Allergens and salt

Fish sauce, salted shrimp and anchovies make traditional kimchi unsuitable for fish or shellfish allergies unless omitted. It is also salty: UGA, citing USDA data, lists 498 mg sodium per 100 g (as of October 2026).

6. Where visitors can join kimjang in fall 2026

We list only events with 2026 dates confirmed by an organizer or news report. Booking pages are mostly in Korean, so a Korean-speaking friend or hotel staff can help.

Event	2026 dates	Where	For visitors
Gwangju Kimchi Festival (광주김치축제)	Oct 23-25	Gwangju Government Complex plaza	Kimchi-making experience, market, master classes; free entry, some programs paid
Goesan Kimjang Festival (괴산김장축제)	Nov 5-8; foreigners' session Nov 5	Goesan Organic Expo Plaza and Sports Complex, North Chungcheong	Pre-booked kimjang with salted cabbage supplied, kimchi market
Bitgoeul Kimjang Daejeon (빛고을 김장대전)	Nov 27-Dec 13	Gwangju Kimchi Town	Individual or group kimjang; kimchi and ingredients for sale

Gwangju Kimchi Festival

The nearest on the calendar. VISITKOREA lists the 33rd edition for October 23-25, 10:00 to 20:00, with free entry and fees for some programs. It is the easiest place to taste many regional styles at once.

Goesan Kimjang Festival

Goesan County is known for salted cabbage (절임배추, jeolim baechu), and its festival is about making kimchi, not watching it. Local media, reporting county announcements, say November 5 is set aside for a foreigners' kimjang session. Main sessions opened for first-come booking on October 8. Reported prices: 148,000 won for a 20 kg general set (20 kg salted cabbage plus 7.5 kg filling) and 76,000 won for 10 kg. That is a lot of kimchi for a traveler, so the foreigners' session or the market is the realistic option. Fifteen farms also run village kimjang from November 1 to 30.

Gwangju Kimchi Town and Seoul

Gwangju's Kimjang Daejeon runs November 27 to December 13. Its booking page lists kimjang participation at 67,000 won without stating the quantity, so confirm before paying.

In Seoul, Museum Kimchikan (뮤지엄김치간) in Insadong, run by Pulmuone, opens Tuesday to Sunday, 10:00-18:00, per its website. It is known for kimchi classes, but its class page would not load when we checked, so contact the museum first. Seoul has held a Seoul Kimjang Culture Festival (서울김장문화제) at Seoul Plaza in past years, including a foreigners' corner in 2019. We found no official 2026 date as of October 20; some sites listing "2026" dates seem to reuse an older schedule. Planning a city base? See where to stay in Seoul and our eSIM and T-money guide.

FAQ

Is kimjang the same as making kimchi?

Not quite. Kimchi is made all year in small amounts; kimjang is the large, usually shared batch made in late autumn to last the winter.

Can tourists join without speaking Korean?

Yes, at events with foreigner sessions such as Goesan's on November 5. The work is easy to follow by watching; booking is the harder part.

Can kimchi be vegan?

Yes. Skip the fish sauce and salted seafood; CSU already lists fish sauce as optional. Fermentation still works because the bacteria come from the vegetables.

Conclusion

Kimjang is less a recipe than people making winter food together, which is why UNESCO listed it. This fall, Gwangju's festival this weekend, Goesan's November 5 session and Kimchi Town later in the season are confirmed ways in. At home, start small, keep it clean and cold, and adjust next time.
