Yes, you can absolutely store kimchi in a glass jar. Glass jars, particularly mason jars, are a popular and effective choice for both fermenting and storing kimchi.
Why Choose Glass Jars for Kimchi Storage?
Glass offers several advantages when it comes to storing fermented foods like kimchi:
- Non-Reactive: Glass does not react with acidic foods, ensuring the flavor and safety of your kimchi remain unaffected over time.
- Visibility: You can easily see the kimchi inside, monitoring its progress during fermentation and checking its condition during storage.
- Easy to Clean: Glass is non-porous, making it simple to sterilize and clean thoroughly between uses.
- Aesthetic: Kimchi looks vibrant and appealing in a clear glass jar.
The Role of the Lid
While the jar itself is suitable, the lid is crucial, especially during the initial fermentation process where gases build up. As the provided reference states, "All you need is a mason jar with a fermentation lid." This type of lid is designed to manage the natural process:
- Gas Release: "You can either use an airlock device or low profile silicone lid to release the build-up of gases in the jar." This prevents pressure from accumulating to dangerous levels.
- Oxygen Protection: These lids also "protect your fermentation from oxygen," which is important for creating the anaerobic (oxygen-free) environment needed for proper lactic acid fermentation.
For long-term storage after active fermentation slows down, a standard airtight lid (like a regular mason jar lid) is sufficient, as gas production significantly decreases. However, always burp the jar occasionally if you notice significant pressure build-up.
Practical Tips for Storing Kimchi in Glass Jars
- Ensure jars and lids are thoroughly cleaned and sanitized before use.
- Pack the kimchi down firmly to remove air pockets and submerge it under its brine.
- Use fermentation lids during the active fermentation phase (typically the first few days to weeks at room temperature).
- Store fermented kimchi in the refrigerator to slow down the fermentation process and extend its shelf life.
- Leave some headspace in the jar, as kimchi can expand slightly and gases may still be produced, even in the fridge.
Storing kimchi in a glass jar with the appropriate lid management is a reliable method for both fermenting and preserving this delicious and healthy food.
