Supermarket Kimchi: A Buyer's Guide
The fact that you can buy kimchi in UK supermarkets is wonderful. Ten years ago, you'd have needed a Korean supermarket. Now it's on the same shelf as pickles and olives. But quality varies enormously.
What's Available
Waitrose: Typically stocks 1-2 brands in the refrigerated section. Quality is generally decent, though mild.
M&S: Often has their own-brand kimchi. Pleasant enough, very accessible flavour.
Tesco: Selection varies by store size. Larger stores have more options.
Sainsbury's: Limited selection but improving.
Whole Foods: If you have one nearby, usually stocks several options including unpasteurised.
Ocado: Online selection is broader than in-store options.
The Pasteurisation Problem
Most supermarket kimchi is pasteurised – heated to kill bacteria for shelf stability. This means:
- No live probiotic cultures
- Longer shelf life
- Milder, less complex flavour
- Softer texture
It's still tasty. It's just not fermented in the traditional sense anymore.
Finding Unpasteurised Options
Some supermarkets do stock unpasteurised kimchi. Look for:
- "Live cultures" on the label
- "Unpasteurised" or "raw"
- Refrigerated (never ambient) storage
- Shorter use-by dates
These are worth seeking out for the probiotic benefits.
Reading Labels
Good signs:
- Short ingredient list
- Recognisable ingredients
- Napa cabbage as the main ingredient
- Gochugaru or Korean chilli flakes
- Fermented fish sauce (for traditional flavour)
Warning signs:
- Long lists of additives
- Vinegar as a main ingredient (not traditionally fermented)
- Vague "flavouring" ingredients
The Flavour Question
Supermarket kimchi is often milder than authentic Korean kimchi. This is deliberate – it's designed for mainstream British palates.
If you're new to kimchi, this isn't necessarily bad. You can develop your taste and then seek out stronger options.
But if you already love bold kimchi, supermarket versions might disappoint.
Cost Considerations
Supermarket kimchi is usually more expensive per gram than what you'd find at Korean supermarkets. You're paying for:
- Smaller portions
- Wider distribution
- Brand marketing
For occasional use, fine. For daily consumption, find a cheaper source.
My Honest Take
Supermarket kimchi serves a purpose: it's accessible, convenient, and introduces people to fermented foods. It's a gateway.
But once you're hooked, move beyond supermarket options. Korean supermarkets offer more authentic products at better prices. Small producers offer superior quality. Making your own offers the best flavour.
Use supermarket kimchi for convenience and discovery. Then graduate to the good stuff.
