Expiration & Storage Tips
When does kimchi expire?
Kimchi, given its fermented nature, has a longer shelf life than many other foods. If unopened and kept refrigerated, commercial kimchi can last up to a year past the printed date. Once opened, provided it's kept refrigerated, kimchi will remain good for up to a month, often longer. With proper refrigeration, homemade kimchi can last for several months to a year. The spicy, tangy, and crunchy dish actually becomes more flavorful over time as it continues to ferment. If frozen, kimchi can last indefinitely, but its texture may change upon thawing.
How do you tell if kimchi is bad?
Although kimchi is fermented, it can still spoil. To tell if it’s bad, look for changes in color, smell and texture. If the cabbage has turned dark or murky, it’s a sign that kimchi has spoiled. A sour or overly spicy smell, beyond the usual tangy odor, can also indicate it's time to throw it out. Lastly, if the texture is slimy or excessively soft, it's likely spoiled. Always discard the kimchi if you see mold, regardless of any other indications.
Tips for storing kimchi to extend shelf life
• Keep kimchi constantly refrigerated. The cold slows down the fermentation, preserving the taste for longer.
• Always use a clean utensil when serving kimchi. Any contamination can cause it to spoil faster.
• Store kimchi in a glass jar with a tight lid to prevent odor from spreading to other foods.
• If you make homemade kimchi, make sure to prepare it in a clean environment and use fresh ingredients to prevent early spoilage.
