For shop-bought kimchi in the UK, look for a jar that lists napa cabbage, gochugaru, garlic, ginger, and salted seafood or a plant-based swap, with no added vinegar or preservatives masking the ferment. Small UK producers such as Mr Kimchi and The Kimchi Company sell fresh, actively fermenting kimchi, while Korean supermarkets and larger Asian grocers stock imported brands with a longer shelf life.
Not all jarred kimchi is made the same way. This guide covers what separates a good jar from a flat one, where to find it in the UK, and what to check on the label.
What to check before you buy
- Live fermentation. A good kimchi is still fermenting in the jar. Look for “unpasteurised” or “live” on the label, and check the jar for small bubbles, a sign the ferment is active.
- Ingredients list. Napa cabbage, Korean chilli flakes (gochugaru), garlic, ginger, spring onion, and salt should sit near the top. Fish sauce or salted shrimp add depth in traditional recipes; vegan versions swap these for soy sauce or seaweed.
- Sugar and vinegar. Some supermarket own-brand kimchi is sweetened or vinegar-forward to mimic the sour taste without a real ferment. This tastes flatter and lacks the gut-friendly bacteria a live ferment gives you.
- Spice level. Gochugaru varies in heat. If you’re new to kimchi, a “mild” label is a safer start.
Where to buy it in the UK
- Korean and Asian supermarkets carry the widest range, including well-known Korean brands imported directly.
- Small UK producers, sold online and in some independent grocers and farmers’ markets, tend to ferment in smaller batches with fresher, more complex flavour.
- Large supermarkets now stock a basic own-brand or a single well-known imported jar in the world food aisle, though the range is limited.

|---|---|---|
| Korean supermarket import | Authentic flavour, bulk buying | Longer shelf life, wide range of heat levels |
| UK small-batch producer | Fresh, actively fermenting kimchi | Shorter shelf life, more complex sour flavour |
| Supermarket own-brand | Convenience | Often milder and less fermented |

FAQ
Is shop-bought kimchi as good as homemade?
A live, small-batch jar comes close. Mass-produced versions are often milder and less fermented, since they’re made to a longer shelf life.
How long does an opened jar of kimchi last?
An opened jar keeps fermenting slowly in the fridge and stays good for several weeks, often becoming more sour over time. Keep it submerged in its own liquid and use a clean utensil each time.
Is all kimchi vegetarian?
No. Traditional kimchi often contains fish sauce or salted shrimp. Check the label if you need a plant-based version, since more UK brands now offer one.
