How to Store Kimchi Properly

Kimchi is a living, fermented food. Proper storage is essential to preserve its flavour, texture, and beneficial probiotics.

Refrigeration Is Important

Kimchi should always be stored in the refrigerator.

Cold temperatures slow down fermentation
Helps maintain a balanced sourness and crunch
Preserves probiotic quality for a longer period

If left at room temperature for too long, kimchi can over-ferment, become overly sour, and lose its desired texture.

Why Glass or Ceramic Jars Are Best for Kimchi

Kimchi is acidic and continues to ferment even after packing.
Glass and ceramic containers are the safest and most suitable materials for storing fermented foods.

Non-reactive: Glass and ceramic do not react with acids produced during fermentation
Odour-resistant: They do not absorb strong fermentation smells
Probiotic-safe: No risk of chemical leaching into the food
Maintains taste: Preserves the original flavour without interference

This is why traditionally, fermented foods across cultures — including kimchi, pickles, and curds — were always stored in earthenware, ceramic, or glass containers.

Why Pouches and Plastic Containers Are Not Advisable

While plastic pouches or containers may seem convenient, they are not ideal for long-term kimchi storage.

Plastic can react: Acidic fermentation may cause plastic to degrade over time
Odour absorption: Plastic absorbs strong smells and flavours
Possible leaching: Prolonged contact with fermented foods may lead to micro-leaching
Texture impact: Soft pouches can trap excess gases and moisture

For a living, naturally fermented food like kimchi, stability and safety matter.
