If you choose fermentation, you’ll know that it’s ready to eat once it starts to smell and taste sour — or when small bubbles begin to move through the jar. After fermentation, you can refrigerate your kimchi for up to 1 year. It will continue to ferment but at a slower rate due to the cool temperature.
Can kimchi be frozen?
For store-bought plastic-wrapped and unopened kimchi, you can stick the product directly in the freezer. If the pack’s been opened, you can either transfer the kimchi in a resealable container or seal the original packaging before sticking in the freezer.
