How Long Does Kimchi Last?
Kimchi keeps for months in the fridge and gets funkier as it ages. How long it lasts, how to store it, and when it's past it.
Like sauerkraut, kimchi preserves itself through the acid it produces, so it lasts for months. It just keeps evolving as it goes.
In the fridge
Move your kimchi to the fridge once it's fermented to your taste. Cold slows the process but doesn't stop it, so kimchi keeps for roughly 3 to 6 months and frequently longer, getting steadily more sour and pungent. Older kimchi is prized for cooking, in stews, fried rice and pancakes, even when it's too funky to eat raw.
| Storage | How long it keeps |
|---|---|
| Fridge, submerged | 3 to 6 months+ |
| Room temperature | Ferments fast, use quickly |
How to store it
- Keep the kimchi under its liquid; press it down so nothing sits exposed on top.
- Use a clean utensil each time.
- Keep the jar sealed and cold, kimchi is pungent and will scent the fridge otherwise.
It gets funkier, not spoiled. Increasing sourness and a stronger smell are the ferment maturing, not going off. Trust fuzzy mould and a genuinely rotten (not sour) smell as your stop signs.
Signs it's past it
Discard kimchi if you see fuzzy mould, if it turns slimy, or if it smells rotten rather than sharply sour and pungent. A little surface yeast or softening is normal. For safety questions on fermented foods, the NCHFP is the authority.
The verdict
Kimchi keeps 3 to 6 months or more in the fridge, growing more sour and funky as it ages, which makes older kimchi great for cooking. Keep it submerged, sealed and handled cleanly, and discard only for fuzzy mould, sliminess, or a rotten smell.
Kimchi keeps 3 to 6 months or longer in the fridge, preserved by its acid and salt, and grows more sour and pungent with age, which is ideal for cooking. Keep it submerged, sealed and handled with clean utensils, and discard only for fuzzy mould, sliminess, or a genuinely rotten smell.
Frequently asked questions
How long does kimchi last in the fridge?
Around 3 to 6 months, often longer, preserved by its acidity and salt. It keeps fermenting slowly even cold, growing more sour and funky over time, which many people prefer for cooking.
Does kimchi go bad?
It sours over months rather than spoiling quickly, but discard it if you see fuzzy mold or it smells putrid rather than sour. Keep it submerged under its brine and use a clean utensil each time.
Can you eat very sour old kimchi?
Yes, if it looks and smells right, sour rather than rotten, with no mold. Older, sour kimchi is prized for cooking, in stews, fried rice and pancakes. When unsure about safety, follow USDA or NCHFP guidance.
