What is Chinese Fermented Cabbage? A Complete Guide
Chinese fermented cabbage goes by several names depending on where in China it is made and how it is prepared. The two most common terms are suancai (酸菜), the sour cabbage of Northern China, and paocai (泡菜), the brine-pickled vegetables rooted in Sichuan cuisine. Both are traditional lacto-fermented foods with deep cultural roots, distinct flavors, and their own fermentation methods. In this guide, you will learn exactly what Chinese fermented cabbage is called, how suancai and paocai differ, why people sometimes call it "Chinese kimchi" or "Chinese sauerkraut," how these foods are made, what they may offer for gut health, and how to buy, store, and cook with them.
The Short Answer: What Is Chinese Fermented Cabbage Called?
The most direct answer is that Chinese fermented cabbage is usually called suancai in Northern China and paocai in Southern and Sichuan regions. Neither term refers to a single product. Instead, each is an umbrella term covering a family of preserved cabbages and vegetables that vary by region, ingredient, brine, and fermentation time.
Beyond these two headline names, you may also encounter other preserved cabbage products with their own names, including Tianjin preserved vegetable (often labeled dōngcài, or "winter vegetable"), zha cai (a pickled mustard stem), and mei gan cai (dried and aged mustard greens). Modern packaged versions may simply be labeled "preserved cabbage," "pickled cabbage," or "sour cabbage," sometimes with pinyin or regional characters on the label.
A quick pronunciation guide can help if you are ordering or asking for these foods:
- Suancai — pronounced "swan-tseye" (suān means "sour"; cài means "vegetable")
- Paocai — pronounced "pow-tseye" (pào means "to soak or steep")
- Dōngcài — pronounced "dong-tseye" (dōng means "winter")
- Zha cai — pronounced "jah-tseye"
- Mei gan cai — pronounced "may-gan-tseye"
Note that traditional varieties vary widely, and modern commercial versions may differ from the classic preparations described here.

What Is Suancai?
Suancai (酸菜) literally means "sour vegetable" and is the classic fermented cabbage of Northern and Northeastern China. It is especially associated with the colder provinces, including Dongbei (the Northeast), where winters historically made fresh vegetables scarce. In traditional suancai, large whole heads of napa cabbage are wilted, salted, packed tightly into crocks or jars, submerged in water or a light brine, and left to ferment for several weeks in a cool place. The result is a deeply sour, earthy, tangy cabbage with a soft but slightly chewy texture.
Because suancai is traditionally made with large pieces or whole leaves and fermented for a longer period, its sourness is pronounced and its flavor is well developed. It is rarely eaten on its own. Instead, suancai is a cooking ingredient — the backbone of hearty Northern stews, hot pots, and dumpling fillings. It is typically rinsed, squeezed, and shredded before being cooked.
What Is Paocai?
Paocai (泡菜) means "soaked vegetable" and refers to vegetables pickled in a seasoned brine, a method most closely associated with Sichuan cuisine. The classic paocai brine is flavored with salt, often Sichuan peppercorns, dried chilies, garlic, ginger, and sometimes a small amount of sugar or liquor. Vegetables — most commonly napa cabbage, but also radish, cucumber, long beans, and mustard greens — are submerged in this brine in a sealed fermentation jar and left for anywhere from a few days to a couple of weeks.
Paocai is generally fermented for a shorter time than suancai, which keeps the vegetables crunchy. The flavor profile is tangy, salty, lightly spicy, and often has the distinctive numbing-citrus note of Sichuan peppercorn. Unlike suancai, paocai is frequently eaten raw or at room temperature, straight from the brine, as a refreshing side dish or appetizer.
Suancai vs. Paocai at a Glance
| Feature | Suancai (酸菜) | Paocai (泡菜) |
|---|---|---|
| Meaning of name | "Sour vegetable" | "Soaked vegetable" |
| Regional home | Northern and Northeastern China | Sichuan and Southern China |
| Main vegetable | Napa cabbage, large leaves or heads | Napa cabbage, radish, cucumber, beans, mustard greens |
| Method | Salted, packed tightly, submerged in water or light brine | Submerged in seasoned spiced brine |
| Typical fermentation time | Several weeks to months | A few days to a couple of weeks |
| Texture | Soft-tender, chewy | Crisp and crunchy |
| Flavor | Deeply sour, earthy | Tangy, salty, often spicy and aromatic |
| How it is eaten | Cooked — in stews, hot pots, dumplings, stir-fries | Often raw or lightly cooked — as a side dish or condiment |
There is also an older umbrella term worth knowing: yanzuicai (腌菜), which simply means "salted/salted-and-stored vegetable" and covers a broad range of Chinese preserved vegetables, including many that are salt-cured rather than genuinely fermented. This is why the terms can overlap — and why context matters when translating Chinese preserved foods into English.

Why People Call It "Chinese Kimchi" or "Chinese Sauerkraut"
If you have searched for Chinese fermented cabbage online, you have likely seen it described as "Chinese kimchi" or "Chinese sauerkraut." These colloquialisms exist because all three foods belong to the same broad family: vegetables preserved through lacto-fermentation, a process in which naturally occurring lactic acid bacteria convert sugars in the vegetables into lactic acid. That acid gives fermented vegetables their characteristic tang and helps preserve them.
Chinese Fermented Cabbage vs. Korean Kimchi
Kimchi and paocai are genuinely related — in fact, there is longstanding historical and cultural discussion in China and Korea about their connection. Both typically use napa cabbage and a salt-based fermentation. However, there are important differences:
- Seasoning: Kimchi is coated with a chili paste gochugaru base, usually combined with garlic, ginger, salted seafood (fish sauce, salted shrimp), and sometimes fruit. Paocai vegetables are submerged in a liquid brine rather than coated in a paste, and the spice profile leans on Sichuan peppercorn and dried chili rather than Korean chili flakes and seafood.
- Method: Kimchi fermentation happens in the paste coating the cabbage; paocai happens in a reusable liquid brine, which is a living culture that can be maintained and reused for months or years.
- Serving: Kimchi is eaten raw as a banchan (side dish) in Korean meals. Paocai is often eaten raw too, but Chinese suancai — the other major Chinese fermented cabbage — is almost always cooked.
So while "Chinese kimchi" is a rough translation people use, it flattens meaningful differences in technique, seasoning, and culinary role.
Chinese Fermented Cabbage vs. German Sauerkraut
Sauerkraut and suancai share the most obvious similarities: both are sour fermented cabbage, both rely primarily on salt and time, and both can be stored for long periods. The differences:
- Cut: Sauerkraut uses finely shredded cabbage, which releases juice and ferments quickly in its own liquid. Suancai uses whole leaves or large chunks submerged in added water.
- Salt ratio and fermentation environment: Sauerkraut typically relies on a measured salt-to-cabbage ratio and the cabbage's own moisture; suancai traditionally uses wilted, salted leaves plus added water in a cool environment over a longer period.
- Culinary use: Sauerkraut can be eaten raw or cooked; suancai is almost always cooked, which changes both its texture and what it contributes to a dish.
The key point: "Chinese sauerkraut" is a reasonable approximation for suancai, but the traditional Chinese technique, texture, and role in the cuisine are distinct.
A Guide to Other Chinese Fermented and Preserved Cabbages
Chinese cuisine has an extraordinarily rich tradition of preserved vegetables, and several other products are closely related to — or frequently confused with — fermented cabbage.
Tianjin Preserved Vegetable (Dōngcài)
Tianjin preserved vegetable, often labeled dōngcài (冬菜, "winter vegetable") or "Tianjin preserved cabbage," is shredded napa cabbage salted heavily, sometimes with garlic, and then sun-dried and aged. It is more of a salt-cured, semi-dried condiment than a sour fermented pickle. It delivers an intensely salty, savory, umami flavor and is used in small amounts — in soups, steamed dishes, and dumpling fillings. Because of the heavy salting and drying, it typically contains little live bacterial activity by the time it is used.
Zha Cai (Pickled Mustard Stem)
Zha cai (榨菜) is made from the swollen stem of a mustard plant, grown especially around Fuling in Chongqing. It is salted, pressed (the name refers to the pressing process), and often chili-seasoned. Although it is not a cabbage, it is often what people encounter labeled as "Sichuan pickled vegetable" or "Chinese pickled cabbage" in packaged form. Shredded zha cai is a classic topping for noodles and congee and appears in soups and stir-fries.
Mei Gan Cai (Dried Preserved Mustard Greens)
Mei gan cai (梅干菜), sometimes called "preserved dried mustard greens," is made by wilting mustard greens, salting, briefly fermenting, and then sun-drying them — often repeating the process. The result is a dark, intensely savory, umami-rich dried product used in famous dishes such as braised pork belly with mei gan cai. Like dōngcài, it is used as a flavoring ingredient rather than eaten as a fresh-tasting pickle.
Regional Variety Beyond Sichuan and the North
While suancai is most associated with the Northeast and paocai with Sichuan, preserved vegetable traditions exist throughout China. Regional pickle traditions include Yangzhou pickles, known for refined, balanced brine-pickled vegetables in Jiangsu cuisine, and Beijing pickles, which include a range of salted and fermented vegetables traditionally prepared for winter. Southern regions produce their own mustard-green pickles, and nearly every province has local variations shaped by climate, available vegetables, and household tradition. In some families, an heirloom paocai brine — sometimes called the "mother brine" — is passed down and maintained for generations, much like a sourdough starter.

Despite the variety of names and regional styles, most Chinese fermented cabbage relies on the same three principles: sufficient salt, an anaerobic (oxygen-free) environment, and time.
Traditional Suancai Method
- Wilt: Whole napa cabbage heads are cleaned and allowed to wilt slightly, which softens them so they pack tightly.
- Salt and pack: The cabbage is salted and pressed firmly into a crock or fermentation jar, often layered with additional salt.
- Submerge: Water or a light brine is added so the cabbage is fully submerged, and a weight keeps everything below the liquid surface.
- Ferment: The crock sits in a cool place — traditionally a cellar or unheated room — for several weeks to months while lactic acid bacteria acidify the batch.
Traditional Paocai Method
- Prepare the brine: Boiled and cooled water is combined with salt and aromatics — commonly Sichuan peppercorns, dried chilies, garlic, ginger, and sometimes rock sugar or a splash of high-proof liquor.
- Add vegetables: Cleaned, cut vegetables are submerged in the brine inside a sealed fermentation jar (often a traditional Sichuan pickle jar with a water-sealed moat around the lid).
- Ferment briefly: The jar sits at room temperature or slightly cool for days to a couple of weeks, depending on taste.
- Maintain the brine: A well-kept paocai brine can be reused repeatedly, with new salt and vegetables added over time; older brines develop a deeper, more complex flavor.
The anaerobic environment is essential in both methods. Submerging vegetables below the brine keeps oxygen away, favoring lactic acid bacteria while discouraging spoilage organisms and mold. Traditional vessels like the water-sealed Sichuan pickle jar are specifically engineered to allow gases to escape without letting air in.
Health Benefits and Probiotic Content
Interest in Chinese fermented cabbage often overlaps with interest in gut health, and there is a genuine scientific basis for that connection — along with important nuances.
Live Cultures and the Gut Microbiome
Lacto-fermented foods are produced by lactic acid bacteria such as Lactobacillus and Weissella species. When these foods are eaten uncooked, they can deliver live microorganisms to the gut, where they may transiently interact with the resident gut microbiome — the vast community of bacteria, fungi, and other microbes living in the digestive tract. Research suggests that regularly eating fermented foods may be associated with greater microbiome diversity and, in some studies, markers of reduced inflammation. However, most of this research is still early, effects vary considerably between individuals, and fermented foods are not a treatment for any medical condition.
It also matters that the gut microbiome differs substantially from person to person, shaped by genetics, diet, medication use, lifestyle, and environment. This is one reason two people can eat the same food and respond differently — a principle that applies to any dietary change, not just fermented foods. For readers curious about their own gut microbial profile, an educational tool such as a gut microbiome test can offer personalized insight into the composition of their gut bacteria, though such testing is informational and does not replace medical evaluation.
The Cooking Nuance: Suancai vs. Paocai
Here is a detail many articles miss: suancai is almost always cooked, and heat destroys the live bacteria. A long-simmered suancai stew still contributes fiber, flavor, and some nutrients from the cabbage itself, but it no longer delivers live probiotic cultures. Paocai, eaten raw from the brine, does retain its live cultures — making it the more relevant choice for anyone specifically interested in live fermented foods.
Other honest caveats: fermented and preserved cabbages can be high in sodium, and some traditional and commercial preparations contain nitrites, which is one reason moderation is commonly advised. Nutritionally, fermented cabbage retains much of the vitamin C, vitamin K, and fiber of fresh cabbage, though levels vary with processing. Anyone managing blood pressure, kidney health, or a sodium-restricted diet should discuss preserved-food intake with a healthcare professional.
How to Use Chinese Fermented Cabbage in Cooking
Understanding how each type is used in its home cuisine helps you choose the right one — and explains why the raw-versus-cooked distinction matters.
Cooking with Suancai
Suancai is the soul of Northern Chinese winter cooking. Classic applications include:
- Suancai bai rou hot pot — a Northeastern hot pot of sour cabbage and sliced pork belly, sometimes with bone broth and blood sausage
- Suancai stew (suancai dun fentiao) — sour cabbage simmered with pork and glass noodles
- Dumpling and baozi fillings — sour cabbage mixed with pork is a beloved cold-weather filling
- Suancai fish soup — a famous Sichuan-style dish (suān cài yú) that pairs tangy suancai with poached fish in a peppery broth
Before cooking, suancai is typically rinsed and squeezed dry, and some cooks briefly blanch it to soften the acidity. Its tang cuts through rich, fatty meats, which is precisely why it pairs so well with pork.

Serving Paocai
Paocai shines as a contrast to plain staples. It is commonly served:
- As a crisp side dish alongside rice porridge (congee), a classic breakfast pairing
- As a palate-cleansing appetizer at the start of a meal
- Chopped into fried rice or noodle dishes for brightness
- As part of a Sichuan-style pickle plate with radish, beans, and cucumber varieties
Because paocai is crunchy and tangy with a hint of spice, it plays a role similar to a relish or quick pickle in Western meals — a small, sharp accent rather than a centerpiece.
Where to Buy and How to Store
Buying
Availability differs by type:
- Suancai: Look for vacuum-sealed bags of shredded sour cabbage in the refrigerated or ambient sections of Asian grocery stores, particularly those catering to Northern or Northeastern Chinese communities. Labels may read "sour cabbage," "pickled cabbage," or "suān cài." Traditional whole-leaf versions are harder to find but occasionally available from specialty producers.
- Paocai: Less common commercially, since quality paocai is often a restaurant or home product. Some brands sell jarred Sichuan paocai or "pickled vegetables"; read labels to distinguish genuinely brine-fermented products from vinegar-based quick pickles, which lack live cultures and have a sharper, less complex sourness.
- Related products: Tianjin preserved vegetable, zha cai, and mei gan cai are widely available in jars and vacuum packs and are labeled clearly by name.
When buying, check the ingredient list: authentic fermented products list cabbage, salt, and aromatics. Vinegar, potassium sorbate, and heavy seasoning are common in modern versions but signal a different product from the traditional fermented item.
Storing
- Refrigerate opened suancai, and keep it sealed in its packaging or an airtight container; use within the timeframe on the label, typically within a few weeks of opening.
- Store paocai fully submerged in its brine in a closed jar in the refrigerator; the brine protects it from oxygen and spoilage. Always use clean utensils when removing vegetables.
- Discard any product with off smells (putrid rather than pleasantly sour), visible mold on surfaces or vegetables, or unusual sliminess combined with other spoilage signs.
- Never store fermented cabbage in sealed containers at room temperature once opened; ongoing fermentation builds pressure.
Homemade versions require particular care: proper salt levels, clean equipment, full submersion, and cool fermentation temperatures all reduce spoilage risk. If a batch smells wrong or shows mold, the safe choice is to discard it.
Key Takeaways
- Chinese fermented cabbage is most commonly called suancai in Northern China and paocai in Sichuan and Southern regions.
- Suancai is a long-fermented, deeply sour napa cabbage used almost exclusively in cooked dishes such as stews, hot pots, and dumpling fillings.
- Paocai is a shorter brine-fermented vegetable, typically seasoned with Sichuan peppercorn and chili, and is often eaten raw and crunchy.
- "Chinese kimchi" and "Chinese sauerkraut" are informal comparisons; the Chinese versions differ from both in brine, seasoning, cut, and culinary role.
- Other preserved cabbage relatives include Tianjin preserved vegetable (dōngcài), zha cai, and mei gan cai, each with its own method and use.
- All traditional types rely on lacto-fermentation: salt, an anaerobic environment, and time.
- Raw paocai may contain live probiotic bacteria, while cooked suancai does not — heat eliminates live cultures.
- Fermented cabbages can be high in sodium, so portion awareness matters for some people.
- Commercial products labeled "pickled cabbage" may be vinegar-based rather than fermented, so ingredient lists matter.
- Individual gut responses to fermented foods vary, and microbiome testing can offer educational insight but is not a diagnostic tool.
Frequently Asked Questions
Is Chinese fermented cabbage the same as kimchi?
No. They are related — both are lacto-fermented cabbages, and paocai in particular shares ancestry and technique with kimchi. But kimchi is typically coated in a chili-seafood paste and eaten raw, while suancai is water-fermented and cooked, and paocai uses a seasoned liquid brine rather than a paste. Each has a distinct flavor, texture, and cultural role.
What is the difference between suancai and paocai?
Suancai is Northern China's long-fermented sour cabbage, made from wilted, salted napa cabbage submerged in water for weeks and used in cooking. Paocai is Sichuan's brine-pickled vegetable, fermented for days in a spiced brine and often eaten raw. Suancai is soft and deeply sour; paocai is crunchy, tangy, and often spicy.
What does Chinese fermented cabbage taste like?
Suancai is intensely sour with earthy, slightly fermented depth and a tender-chewy texture. Paocai is brighter and milder — tangy, salty, crisp, and often carrying mild heat and the citrusy-numbing note of Sichuan peppercorn. Salt-cured relatives like dōngcài and mei gan cai taste predominantly salty and umami-rich.
Can you eat napa cabbage raw?
Yes, fresh napa cabbage can be eaten raw and is commonly used raw in salads and slaws. In the context of fermented foods, raw paocai is eaten as-is from the brine, while suancai is generally cooked before serving. Homemade fermented vegetables should only be eaten raw if prepared and stored properly.
Are fermented cabbage and pickled cabbage the same?
Not always. Fermented cabbage is preserved by lactic acid bacteria converting sugars into lactic acid, while many commercial "pickled cabbages" are preserved with added vinegar and heat processing. In Chinese usage, translations blur the two: suancai and paocai are genuinely fermented, but products labeled "pickled cabbage" may be vinegar-based quick pickles with no live cultures.

Cloudiness is usually normal and expected — it reflects the growth of lactic acid bacteria and is a sign of active fermentation. What matters more is smell and surface condition: a pleasantly sour, clean aroma is fine, while putrid odors, fuzzy mold, or slimy vegetables indicate the batch should be discarded.
How long does Chinese fermented cabbage last?
Unopened, commercial products last according to their labeled dates, often many months due to salt and acidity. Once opened, refrigerate suancai and use it within a few weeks; keep paocai submerged in its brine in the refrigerator, where a well-maintained jar can keep for weeks or longer if handled cleanly. Always rely on smell, appearance, and labeled guidance.
Does cooking suancai kill the probiotics?
Yes. Live lactic acid bacteria are sensitive to heat, so simmering suancai in stews or hot pots destroys the live cultures. Cooked suancai still contributes flavor, fiber, and some nutrients, but if live cultures are your goal, raw paocai or another uncooked fermented food is the more relevant choice.
Is Chinese fermented cabbage healthy?
It can be a flavorful part of a balanced diet, providing fiber, some vitamins, and — when eaten raw — live bacteria that research suggests may support microbiome diversity. It is also typically high in sodium, and moderation is sensible. It is a food, not a medicine, and it should not replace medical care or a varied diet.
Can I make suancai or paocai at home?
Yes, both are approachable home projects. The essentials are clean equipment, adequate salt, full submersion in brine, an oxygen-free sealed jar, and a cool fermentation spot. Many beginners find paocai easier because it ferments quickly in a reusable brine. Follow well-reviewed recipes closely, monitor for spoilage, and discard anything that seems off.
Can fermented foods help my gut?
Research suggests that regularly consuming fermented foods may be associated with a more diverse gut microbiome, though individual responses vary widely and the evidence is still developing. Fermented foods are best viewed as one component of a fiber-rich, varied diet rather than a targeted fix. If you have persistent digestive symptoms, consult a healthcare professional rather than self-treating.
What should I look for on labels when buying?
For genuinely fermented products, look for short ingredient lists — cabbage, salt, and aromatics — and terms like "fermented" or the pinyin names. Vinegar early in the ingredient list, pasteurization, or preservatives like potassium sorbate suggest a vinegar pickle rather than a live fermented product. Sodium content is also worth checking.
Conclusion
So, what is Chinese fermented cabbage called? Most often, suancai or paocai — with suancai being the long-fermented, deeply sour cabbage of the North that stars in stews and dumplings, and paocai being the crisp, tangy, spiced brine pickle of Sichuan eaten straight from the jar. The informal labels "Chinese kimchi" and "Chinese sauerkraut" point to real shared roots in lacto-fermentation, but each of these foods has its own technique, flavor, and place at the table.
Knowing the names and the raw-versus-cooked distinction also clarifies what each food offers: raw paocai may deliver live cultures that interact with the gut microbiome, while cooked suancai contributes flavor and nutrients without live bacteria. Because gut responses to any food vary from person to person, and symptoms alone rarely reveal what is happening inside the digestive tract, some readers find it useful to learn more about their own microbial profile through tools such as microbiome testing — an educational window into individual gut composition rather than a medical diagnosis. Whether you choose to cook with suancai or snack on paocai, understanding the names, methods, and traditions behind Chinese fermented cabbage turns a confusing category into a genuinely rewarding one to explore.
