What Is Kimchi?
Kimchi is Korea's signature fermented vegetable dish, most commonly made from napa cabbage salted and packed with a spice paste of gochugaru (Korean chili flakes), garlic, ginger, scallions, and radish. It's tangy, spicy, funky in the good fermented way, and it shows up everywhere from side dishes to fried rice, stews, and tacos. On paper, it sounds like it should be automatically vegan — cabbage, chili, garlic, salt, time. In practice, it's one of the more deceptive foods on a vegan shopping list, because the ingredient that makes commercial kimchi taste like kimchi rather than spicy sauerkraut is often something that didn't come from a plant at all.
Why Kimchi Is Ambiguous for Vegans
The confusion isn't about the cabbage, the radish, or the chili paste — those are almost always plant-based. It's about umami. Traditional Korean kimchi recipes build savory depth using fermented seafood, and that seafood is often blended directly into the seasoning paste rather than listed as an obvious topping you could pick out. A jar can look, smell, and taste completely plant-based while containing a small but meaningful amount of fish or shellfish product mixed evenly through every bite. That's what makes kimchi genuinely ambiguous, as opposed to something like a cheeseburger where the animal ingredient is obvious.
To make things more confusing, the food industry hasn't standardized this. Some of the biggest kimchi brands in the world sell a "traditional" version with fish sauce right next to a "vegan" version with none, using nearly identical packaging. Grabbing the wrong jar off the same shelf, from the same brand, is an easy mistake.
The Ingredients to Watch For: Fish Sauce and Salted Shrimp
Two ingredients are responsible for almost all non-vegan kimchi:
- Aekjeot (fish sauce): A fermented fish sauce, traditionally made from anchovies or sand lance, used to add salty, savory depth to the kimchi paste. It's usually listed on labels simply as "fish sauce" or "anchovy extract."
- Saeujeot (salted fermented shrimp): Tiny shrimp salted and fermented for months, then stirred into the paste either whole or pureed. On an ingredient label this can appear as "shrimp," "salted shrimp," or "shrimp paste."
Some recipes and products use both. Others use one or the other. A smaller number use neither and instead lean on ingredients like kelp/kombu broth, soy sauce, miso, or extra salt and sugar to build the same savory backbone — which is exactly what makes a kimchi vegan without sacrificing much of the flavor traditional recipes are going for.
One thing to watch out for specifically: "fish sauce" and "shrimp" don't always appear near the top of the ingredient list, since they're used in relatively small quantities. That means a quick glance isn't always enough — you generally need to read the full ingredient panel, not just skim the first few items.
So, Is Kimchi Vegan?
It depends entirely on the recipe or brand — there is no single correct answer for "kimchi" as a category. Traditional, restaurant-style, and many mass-market Korean kimchi brands are not vegan by default because they use fish sauce and/or salted shrimp for flavor. At the same time, fully vegan kimchi is widely available, both from dedicated vegan-focused brands and as a specific labeled SKU from mainstream Korean kimchi companies that also sell a traditional version.
The practical takeaway: never assume a jar of kimchi is vegan just because it's kimchi, and never assume it isn't, either. You have to check that specific product.
Brand-by-Brand Breakdown
Formulations change, and brands sometimes run multiple product lines under the same name, so this should be treated as a starting point rather than a substitute for reading the label on the jar in front of you. When in doubt, run the ingredient list through the spvegan.com ingredient checker before you buy.
| Brand | Vegan Status | Notes |
|---|---|---|
| Jongga (Original line) | Not vegan | The standard "Original" line uses fish sauce. Jongga also sells a separately labeled "Vegan" product — look for the word "vegan" on the front of the jar. |
| Mother-in-Law's Kimchi | Varies by SKU | Sells a Vegan Napa Cabbage Kimchi explicitly labeled as such. Other varieties in the lineup may differ, so match the exact product name. |
| Wildbrine | Vegan | Markets its Korean-style kimchi as vegan across the line and has been outspoken about deliberately formulating without fish sauce or shrimp. |
| Cleveland Kitchen | Vegan | Classic Kimchi is labeled "vegan friendly" on retail listings and uses a plant-based brine. |
| Trader Joe's Kimchi (Spicy Fermented Napa Cabbage) | Generally considered vegan | Widely reported by ingredient-tracking sites as free of animal-derived ingredients, but formulations can change — check the current label. |
| Mama O's | Varies by SKU | Sells both an Original Kimchi and a separately labeled Vegan Kimchi as distinct products — they are not the same jar. |
| Sunja's Kimchi | Check label | Ingredient sourcing isn't consistently documented across varieties; verify the specific product's label before buying. |
Note the pattern: several of the biggest names in commercial kimchi make both a traditional and a vegan version, sold as different products with different labeling. That's the single most common source of "wait, I thought this brand was vegan" mistakes.
How to Check the Label Yourself
You don't need to memorize brand lists to shop safely. A quick label check takes about ten seconds:
- Scan the full ingredient list for "fish sauce," "anchovy," "anchovy extract," "shrimp," "salted shrimp," or "shrimp paste." These are the words that matter most.
- Look for a front-of-package "vegan" or "plant-based" claim. In the U.S., a brand generally won't put "vegan" on the label unless the formulation supports it, so it's a reasonably reliable shortcut when present — though it's still worth spot-checking the ingredients.
- Be extra cautious with restaurant or deli-counter kimchi, where there's no ingredient label at all. If you're vegan and eating out, it's worth asking directly whether the kitchen's kimchi uses fish sauce or shrimp, since most traditionally prepared versions do.
- Watch for "may contain" or shared-facility disclaimers if you're avoiding cross-contact for allergy reasons rather than strict dietary preference — those are a separate issue from the ingredient list itself.
If you want a faster way to scan a full ingredient panel for hidden animal-derived ingredients across kimchi or anything else in your cart, the spvegan.com ingredient checker is built for exactly this kind of label-reading.
What Vegan Kimchi Actually Tastes Like
The honest answer is: close, but not always identical to the traditional version. Fish sauce and salted shrimp contribute a specific savory, slightly funky depth that's hard to fully replace. Well-made vegan kimchi compensates with a combination of extra salt, sugar, kelp or kombu-based broth, and sometimes a splash of soy sauce or miso to round out the umami. Brands that have been doing this for a while, like Wildbrine and Cleveland Kitchen, tend to land closer to the traditional flavor than a quick homemade substitution does. If you've only ever had traditional kimchi and try a vegan version for the first time, expect it to read as slightly milder and less pungent rather than dramatically different — most people find it a completely satisfying substitute rather than a compromise.
Making Vegan Kimchi at Home
If you'd rather control the ingredients entirely, homemade vegan kimchi is straightforward and lets you skip the fish sauce question altogether. The basic swap is replacing the traditional fish sauce or shrimp paste with a combination of soy sauce (or tamari for gluten-free), a small amount of sugar, and a kelp or shiitake-based broth reduced down for depth. Some home cooks also add a spoonful of white miso for extra fermented complexity. The salting, seasoning, and fermentation process is otherwise identical to a traditional recipe, and the fermentation itself — the part responsible for kimchi's signature tang and probiotic content — doesn't require any animal ingredients at all.
Who Should Pay Closest Attention to This
This matters most for strict vegans and for anyone avoiding fish or shellfish for allergy reasons, since fish sauce and shrimp paste are exactly the kind of ingredients that can hide in a product that looks entirely plant-based at a glance. It's a lower priority if you're vegetarian-leaning but flexible about small amounts of fish-derived seasoning, or if you're buying specifically from a brand's dedicated vegan product line where the labeling has already done the work for you. Either way, kimchi is common enough in grain bowls, fried rice, tacos, and side-dish spreads that it's worth the ten seconds it takes to check.
Final Verdict
Kimchi as a category is not automatically vegan, and treating it as a "safe" plant-based side dish without checking is one of the more common label-reading mistakes vegans make. Traditional recipes and a meaningful share of commercial brands rely on fish sauce or salted shrimp for flavor. That said, this is one of the easier animal ingredients to avoid once you know what you're looking for: dedicated vegan brands are widely available, several mainstream Korean kimchi companies now sell a clearly labeled vegan version alongside their traditional line, and the ingredient list gives you a definitive answer in seconds rather than leaving you guessing.
Vegan-friendliness of kimchi as a category: 6/10 — genuinely mixed by default, but easy to navigate correctly once you know the two ingredients to look for and check the label every time.
