Kimchi Containers and Fermentation Gear for a US Kitchen
김치통과 발효 도구
In Korea, kimchi is less a side dish than a household system. There are containers stacked in the fridge, often a second fridge just for kimchi, and the annual tradition of gimjang (김장) — making a big batch of kimchi in late autumn to last through winter, which is recognized by UNESCO as Intangible Cultural Heritage. You don't need any of that scale in a US kitchen, but a little of the same thinking — the right container, the right size, and clean habits — makes homemade or store-bought kimchi much easier to live with.
How Korean homes store kimchi
Three things show up in most Korean kitchens:
- The kimchi container — gimchitong (김치통). Usually a rectangular, airtight plastic box with a gasketed lid that latches on all four sides. They come in many sizes and stack neatly.
- The kimchi refrigerator — gimchi naengjanggo (김치냉장고). A separate appliance (often a chest or upright style) with settings intended to keep kimchi at a steady, cold temperature. Its main jobs are slowing fermentation, keeping texture, and isolating the smell.
- Onggi (옹기). Traditional breathable earthenware jars. Historically, large onggi were stored outdoors on a terrace called jangdokdae (장독대) or partly buried in the ground during winter to keep kimchi cold and stable. Today many urban households use onggi for soy sauce, doenjang, and other pastes more than for everyday kimchi.
For most US kitchens, the practical takeaway is a couple of good airtight containers sized to what you'll actually eat.
Container materials compared
| Material | Pros | Cons |
|---|---|---|
| Food-grade plastic (often polypropylene) | Light, inexpensive, stackable, unbreakable, widely available with latch lids | Absorbs smell and red stains over time; can scratch |
| Glass | Doesn't absorb odor or color, easy to see fermentation, easy to clean | Heavy, breakable; wide-mouth jars can be awkward to scoop from |
| Stainless steel | Durable, odor-resistant, doesn't stain | Opaque; quality of lids and gaskets varies a lot |
| Onggi earthenware | Traditional, breathable, good for long ferments | Heavy, fragile, requires care, and lid fit is often loose for fridge use |
| Ceramic crocks with water seal | Good for larger batches and sauerkraut-style ferments | Bulky; not designed for fridge storage |
Avoid reactive metals such as aluminum or bare cast iron for storage. Kimchi is salty and becomes acidic as it ferments.
A note on plastic and stains
Gochugaru (고춧가루, Korean chili flakes) will tint most plastic orange over time. That's cosmetic. To keep things simple, many people dedicate one container to kimchi and nothing else. If you want to avoid stains and smell transfer altogether, choose glass or stainless steel.
Choosing the right size
Size matters more than material. Kimchi ferments best when it's packed down with little air above it, and it releases gas and liquid as it goes.
- Match container to batch. A small household might use a 1–2 liter container for a store-bought jar's worth of kimchi. A whole napa cabbage (baechu, 배추) batch usually needs considerably more.
- Several small beats one huge. Opening a large container every day exposes all of the kimchi to air. Many Korean cooks portion a batch into one "eating" container and keep the rest sealed.
- Leave headspace. Fill to roughly 70–80% and press the kimchi down under its brine.
- Check your fridge. Measure the shelf height before buying tall containers.
Gear for your first batch
If you're making kimchi rather than just storing it, here's what's useful.
Essentials
- A large mixing bowl or basin. Salting a whole napa cabbage takes space. Korean households often use wide stainless or plastic basins called daeya (대야). A large stainless bowl works fine.
- Food-safe gloves. Gochugaru and garlic will sting and stain your hands. Long rubber kitchen gloves (gomu jangap, 고무장갑) are a Korean kitchen fixture.
- Coarse salt. Korean recipes commonly call for coarse sea salt, cheonillyeom (천일염), for salting cabbage. Fine table salt behaves very differently by volume, so follow your recipe's guidance.
- A colander. For rinsing and draining salted cabbage.
- Airtight containers as described above.
Nice to have
- A food processor or blender for the garlic, ginger, and fruit that go into the seasoning paste.
- Fermentation weights or a smaller lid to keep vegetables under brine in a jar.
- A kitchen scale. Salting is easier to repeat when you weigh cabbage and salt.
- Labels or tape to date each container.
Fermentation basics (the short version)
Recipes vary by household and region, but the general pattern is:
- Salt the vegetables to draw out water and season them.
- Rinse and drain, then mix with a seasoning paste (often gochugaru, garlic, ginger, fish sauce or salted shrimp, and scallions).
- Pack tightly into a clean container, pressing out air pockets, and leave headspace.
- Ferment briefly at room temperature — often around a day or two, depending on warmth and taste — then move it to the fridge, where fermentation continues slowly.
- Taste as you go. Kimchi gets more sour over time. Fresh kimchi (geotjeori, 겉절이) is eaten almost immediately, while well-fermented, sour kimchi (mugeunji, 묵은지) is prized for stews like kimchi jjigae.
Food safety: Use clean utensils every time, keep vegetables submerged, and keep the rim clean. If you see fuzzy mold, smell something off rather than pleasantly sour, or are unsure, throw it out. For tested home-fermentation guidance, the National Center for Home Food Preservation is a useful reference.
Dealing with kimchi smell
The most common complaint from US households isn't fermentation — it's the fridge smelling like garlic and fish sauce. A few habits help:
- Use gasketed, latching lids and check that the silicone seal is seated properly.
- Wipe the rim and lid with a paper towel after scooping. Brine on the outside of the container is the main culprit.
- Don't overfill. Fermentation gas can push brine past the seal.
- Put the container in a bag or a second box if your fridge is small.
- Glass or stainless containers retain less smell than plastic between batches.
- Clean plastic with baking soda, and air it out in sunlight if possible; sunlight is a traditional Korean trick for fading smells and stains.
- Consider a small second fridge if kimchi becomes a regular habit. It's the US equivalent of the kimchi refrigerator.

- Airtight lid with a removable gasket you can wash.
- Clear capacity in liters or quarts — compare against your fridge shelf.
- Food-safe material stated by the seller (for plastics, many listings say BPA-free; check what's stated).
- Rectangular shape if you want to stack containers efficiently.
- Wide opening for scooping and pressing kimchi down.

Bottom line
Start with one or two well-sealing containers in the size you'll actually use, keep them dedicated to kimchi, and leave a little room at the top. Add glass or stainless if smell bothers you, and an onggi if you want to explore longer traditional ferments. The Korean kitchen system is built on that simple idea: keep kimchi sealed, cold, and pressed down, and it will take care of itself.
Frequently asked questions
What is the best container for kimchi?
There isn't one best material. Airtight food-grade plastic is light and common in Korean homes; glass doesn't absorb odors or stains; stainless steel is durable and odor-resistant; onggi earthenware is traditional and breathable. The most important features are a tight-sealing lid, the right size, and room for the kimchi to stay submerged in its brine.
How do I stop kimchi from making my fridge smell?
Use a container with a gasketed, airtight lid, don't overfill it, wipe the rim and lid clean after each use, and consider a dedicated kimchi container or a second small fridge. Glass and stainless steel tend to hold onto smells less than plastic.
How full should a kimchi container be?
Leave some headspace, because kimchi releases gas and liquid as it ferments. Many people fill to roughly 70–80% and press the kimchi down so it stays under its brine. Overfilled containers can leak or bulge.
Can I ferment kimchi in a metal container?
Stainless steel containers are commonly used for kimchi. Avoid reactive metals such as aluminum or uncoated iron, because the salt and acidity can react with them.
What is a kimchi refrigerator?
A kimchi refrigerator (gimchi naengjanggo, 김치냉장고) is a dedicated appliance found in many Korean homes. It's designed to hold kimchi at steady, cold temperatures with settings for different stages of fermentation, and to keep its smell away from other food.
Should I burp my kimchi jar?
Many people open or press down the kimchi in the first days of room-temperature fermentation to release gas and keep vegetables submerged. Once it's in the fridge, fermentation slows a lot. Using a clean utensil each time helps prevent unwanted mold.
