1. Why Traditional Korean Kimchi Is NOT Vegan or Shellfish-Free
First-time shoppers are often shocked to learn that traditional Korean restaurant and supermarket kimchi is NOT vegetarian or vegan. Even though napa cabbage (baechu) and radish (mu) are vegetables, traditional Korean kimchi fermentation relies on marine amino acids (jeotgal) to feed lactic acid bacteria (Lactobacillus) and create deep umami:
- Salted Fermented Shrimp (μμ°μ / Saeujeot): Tiny whole crustaceans fermented in sea saltβa major FDA Crustacean Shellfish allergen that can trigger anaphylaxis in shrimp/crab-allergic diners.
- Anchovy & Sand Lance Fish Sauce (λ©ΈμΉμ‘μ / κΉλ리μ‘μ ): Fermented finfish extractβa mandatory FDA Fish allergen.
- Raw Oysters or Squid (κ΅΄ / μ€μ§μ΄): Frequently added to fresh winter kimchi (bossam kimchi) in Korean BBQ restaurants.
2. Saeujeot (Shrimp) vs. Aekjeot (Anchovy): Understanding Crustacean Allergy Risk
If you have a crustacean shellfish allergy (shrimp, crab, lobster) or a finfish allergy, you must never assume restaurant banchan kimchi is safe. For example, the best-selling Jongga Sliced Napa Cabbage Kimchi tub at Costco lists both Salted Shrimp and Anchovy Sauce on its US nutrition label.
Thankfully, the explosion of plant-based dining in the US has prompted both heritage Korean makers (Jongga, Pulmuone/Nasoya) and American craft fermenters (Cleveland Kitchen, Mother-in-Law's, Wildbrine) to replace seafood with kelp (kombu) stock, fermented soybean umami (Yondu/miso), and nutritional yeast.

4. How to Make Restaurant-Style Vegan Kimchi Jjigae Without Anchovy Broth
In Korea, Kimchi Jjigae (kimchi stew) and Sundubu Jjigae (soft tofu stew) are typically simmered in an anchovy-kelp stock (myeolchi dashima yuksu). To achieve the exact same deep, savory restaurant broth at home with zero fish or shellfish:
- Simmer dried kelp (dashima) and dried shiitake mushrooms in water for 10 minutes.
- Add 1 tablespoon of Sempio Yondu Vegetable Umami Essence (certified Vegan & Gluten-Free).
- Stir-fry aged Vegan Kimchi in toasted sesame oil (or perilla oil) with 1 tsp of pure Korean Gochugaru before pouring in the broth and soft tofu!
Frequently Asked Questions (FAQ)
Does Costco Jongga Kimchi have shellfish?
Yes! The standard large tub of Jongga Sliced Napa Cabbage Kimchi sold at US Costco warehouses contains salted fermented shrimp (crustacean shellfish) and anchovy sauce (fish). Look specifically for the green-lid Jongga Vegan Kimchi at Walmart/Target/H Mart if you have a shellfish allergy.
Is Trader Joe's Kimchi vegan and fish-free?
Yes, Trader Joe's Spicy & Tangy Napa Cabbage Kimchi in the refrigerated produce section is 100% vegan and formulated without fish sauce or shrimp.
Is kimchi naturally gluten-free?
Almost all napa cabbage kimchi is naturally gluten-free because traditional kimchi binder paste is made with sweet glutinous rice flour (chapssal-pul), not wheat. However, always check specialty kimchi varieties that may add soy sauce.
