What Is Kimchi?
Kimchi is a Korean side dish made from vegetables, usually napa cabbage or Korean radish, salted and fermented with a spice paste of gochugaru (Korean chili flakes), garlic, ginger, and scallions. It's tangy, spicy, funky, and loaded with live cultures from the fermentation process. On paper, it looks like it should be one of the easiest vegan wins in the condiment aisle: it's fermented cabbage. What could possibly be non-vegan about that?
Here's the problem. Traditional kimchi recipes don't stop at vegetables and chili flakes. Most authentic recipes, and most of the kimchi sold in American grocery stores, use a seafood-based ingredient to build savory depth. That single ingredient is the difference between a jar being vegan and a jar containing fish products, and it's rarely obvious from the front label.
Why Kimchi Is a Vegan Gray Area
The confusion comes down to umami. Cabbage and chili alone taste flat and one-dimensional once fermented. Korean cooks have historically solved this the same way many cuisines solve it: with fermented seafood. Salted, fermented shrimp or fish adds a savory, almost cheese-like funk that rounds out the sourness of the ferment and gives commercial kimchi its deep, complex flavor.
That means a jar of kimchi can look completely plant-based on the front of the package, list mostly vegetables on the ingredient panel, and still contain a small but meaningful amount of animal product buried a few lines down. Unlike a burger patty, where you'd expect meat, kimchi doesn't signal its non-vegan status visually or even by smell to most people unfamiliar with it. That's exactly why this label deserves a second look, and why we'd point you to the spvegan.com ingredient checker if you want to scan a specific jar's ingredient list rather than trust the front-of-pack marketing.
The Ingredients to Watch For
When you flip a jar of kimchi around, these are the specific ingredients that mean it isn't vegan:
- Fish sauce (aekjeot): A fermented liquid made from anchovies or other small fish, used for salty, savory depth. Often listed simply as "fish sauce" or "anchovy extract."
- Salted shrimp (saeujeot): Tiny fermented shrimp, sometimes whole, sometimes as a paste, mixed directly into the seasoning paste. Look for "salted shrimp," "shrimp paste," or "saeujeot."
- Anchovy paste or extract: A concentrated seafood seasoning used in place of, or alongside, fish sauce.
- Oyster sauce: Less common in kimchi specifically, but shows up occasionally as a flavor booster in some commercial recipes.
Any one of these on the ingredient list means the product is not vegan, and typically not vegetarian either since fish sauce and shrimp paste don't fit a lacto-ovo-vegetarian diet.
Is Kimchi Vegan? The Short Answer
Not by default. Traditional and most "authentic-style" kimchi contains fish sauce or salted shrimp. But a growing number of brands now sell dedicated vegan formulations, usually built around seaweed or kelp powder to replace the umami that fish sauce would normally provide. The honest answer is that you cannot assume either way just from a brand name or the fact that a jar is sold at a natural foods store. You have to check the ingredient list, or specifically look for the word "vegan" printed on the label, every single time.
Brand-by-Brand: Which Kimchi Is Actually Vegan
We looked at ingredient information across the most widely distributed U.S. kimchi brands. A few important caveats: some brands sell both a traditional (fish-based) line and a separate vegan line side by side, and formulations can vary by flavor or region, so always confirm on the specific jar in front of you rather than relying on brand reputation alone.
| Brand | Vegan Status | Notes |
|---|---|---|
| Mother-in-Law's (Vegan Napa Cabbage Kimchi) | ✅ Vegan | Uses seaweed instead of fish sauce. Sold as a distinct SKU — the brand's traditional/original line is not vegan, so check which jar you're grabbing. |
| Wildbrine | ✅ Vegan | Korean Style and Probiotic Fermented Kimchi lines use seaweed for umami rather than fish sauce. |
| Jongga (Vegan line) | ✅ Vegan | Sells a variety explicitly labeled "Vegan" alongside its traditional fish sauce–based kimchi. |
| Bibigo (Vegan Kimchi) | ✅ Vegan | Clearly labeled vegan on the jar; a good beginner pick since there's no guesswork. |
| Mama O's (Vegan version) | ✅ Vegan (specific SKU only) | The brand offers a fish-free version, but its standard Premium Kimchi contains anchovy paste — read the label carefully. |
| Seoul Kimchi (Lucky Foods) | ✅ Vegan | Vegan recipe available in original and spicy; the brand's non-vegan version uses shrimp and anchovy. |
| King's | ✅ Vegan | Marketed as vegan with no fish ingredients. |
| 1000 Year Kimchi | ✅ Vegan | Formulated without any fish products. |
| Simple Truth (Kroger) | ✅ Vegan | Store-brand option, no fish sauce in the ingredient list. |
| Cleveland Kitchen | ⚠️ Mixed reports — verify label | Some retailers list the mainstream lineup as vegan, but not every source agrees across every flavor. Check the jar before buying. |
| Sunja's | ⚠️ Mixed — has both lines | The brand sells a traditional fish sauce–based kimchi and, separately, a vegan version. Read carefully; don't assume by flavor name. |
| Choi's | ❌ Likely not vegan | Traditional recipe; no confirmed vegan SKU found. Check the label directly. |
Nutrition Comparison: Vegan Kimchi Brands
Kimchi is low-calorie across the board, but sodium varies more than you'd expect between brands. Here's how three confirmed vegan options stack up per roughly 1-ounce serving:
| Brand | Serving Size | Calories | Sodium | Carbs | Fiber | Sugar | Protein |
|---|---|---|---|---|---|---|---|
| Cleveland Kitchen Kimchi | 28g | 10 | 270mg | 3g | 1g | 2g | 0g |
| Wildbrine Korean Style Kimchi | 30g (2 tbsp) | 10 | 280mg | 2g | 1g | 1g | 1g |
| Mama O's Premium Kimchi | 30g (6 pieces) | 10 | 140mg | 2g | 0g | 1g | 0g |
If sodium is a concern, Mama O's runs noticeably lower per serving than Cleveland Kitchen or Wildbrine, though all three are salty enough that kimchi should be treated as a condiment or side, not a base ingredient you're eating by the cup.
Same Brand, Different Jar: Why Labels Matter
Mother-in-Law's is the clearest example of why brand reputation alone doesn't tell you anything. The company sells its well-known traditional kimchi, which is fermented with fish products the classic way, right alongside a separate "Vegan Napa Cabbage Kimchi" that swaps in seaweed for umami. Both jars sit on the same shelf, sometimes inches apart, with similar packaging. Grabbing the wrong one is an easy mistake if you're moving fast through the fridge aisle.
Sunja's follows a similar pattern. This is becoming more common industry-wide as brands realize there's real demand for a vegan option without wanting to reformulate their entire product line. The takeaway: don't shop by brand name. Shop by the word "vegan" on the label, or by actually reading the ingredients.
How to Check a Kimchi Label Like a Pro
- Look for the word "vegan" first. If it's printed clearly on the front, that's your fastest confirmation, though it's still worth a quick ingredient scan to be sure.
- Scan for fish sauce, anchovy, or shrimp paste. These are usually near the middle of the ingredient list, after cabbage, water, and salt.
- Watch for vague seafood language. Terms like "seafood extract" or "fish extract" are still animal-derived even if they don't say "fish sauce" explicitly.
- Don't trust "traditional" or "authentic" as marketing language. These words often signal the fish sauce version, not the vegan one.
- When in doubt, use a scanner. Running the barcode or ingredient list through the spvegan.com ingredient checker takes the guesswork out of it, especially for smaller regional brands that don't clearly label vegan status.
Making Vegan Kimchi at Home
If you'd rather skip the label-reading entirely, homemade kimchi is genuinely one of the easier fermentation projects to pick up, and it puts you in full control of the ingredients. Most vegan recipes swap fish sauce and shrimp paste for a combination of soy sauce or tamari, a small amount of miso, and either dried kelp (dashima) or kombu soaked in water to mimic the oceanic depth that fish sauce provides. Some recipes add a spoonful of blended fermented soybean paste or a touch of nutritional yeast for extra umami. The fermentation process itself, salting the cabbage, mixing in the chili paste, and letting it sit at room temperature for a few days, doesn't change at all based on whether you use fish sauce or its plant-based substitutes.
Comparison: Vegan Kimchi vs. Traditional Kimchi
| Factor | Vegan Kimchi | Traditional Kimchi |
|---|---|---|
| Umami source | Seaweed, kelp, or soy-based seasoning | Fish sauce or salted shrimp |
| Flavor profile | Slightly milder, less funky depth | Deeper, more pungent umami |
| Availability | Growing, but still a minority of SKUs on shelf | Still the dominant style in most grocery stores |
| Price | Comparable, occasionally $1–2 more per jar | Standard pricing |
| Vegetarian-friendly | Yes | No |
Who Should Pay Attention to This
This matters most for strict vegans and vegetarians who eat Korean food regularly, whether that's kimchi straight from the jar, kimchi fried rice, kimchi jjigae, or as a topping on grain bowls. It's also worth knowing if you're vegan and eating at Korean restaurants, since the complimentary banchan (side dishes) almost always includes kimchi made with the traditional fish-based recipe unless the restaurant explicitly offers a vegan version. If you're only occasionally vegan-curious or flexitarian, this is a lower-stakes issue, but it's still good to know what you're actually eating.
Final Verdict
Kimchi is not inherently vegan, and most of what you'll find on a typical grocery shelf still contains fish sauce or salted shrimp. The good news is that vegan kimchi has gone from a niche specialty item to something you can find at most major grocery chains, from Wildbrine and Bibigo's dedicated vegan lines to store-brand options like Simple Truth. The bad news is that you genuinely cannot assume vegan status from the brand, the packaging color, or whether it's sold at a natural foods store. Read the label every time, look specifically for "vegan" on the front, and scan the ingredient list for fish sauce, anchovy, or shrimp paste before it goes in your cart.
