I'm not going to lie, we eat a ridiculous amount of kimchi and there is never any left to freeze so I cannot speak to this with much authority. But, I did a little digging and found this article at Pantry Tips. It's a super helpful post and well worth a look. "Yes, you can freeze kimchi. By freezing kimchi, you can extend their shelf life for up to 7 years. Kimchi will need to be stored in an airtight container or freezer bag and sealed tight to prevent air from leaking in. Any air that gets in the container or bag can cause freezer burn to the kimchi."
