Conclusion

It is better to store walnuts unshelled and shelled walnuts do not stay fresh for that long. Storing walnuts in a cool and dry place, in an airtight container is preferred. When a package of walnuts is opened, they should be stored in the freezer in a sealed bag so that moisture doesn’t get in.

Shelled walnuts when stored properly can even last for a year in the refrigerator and unshelled walnuts longer than that. When they are not placed in an air-tight container, it is better to seal them in a resealable heavy-duty freezer bag.

When someone wants to store the shelled walnuts indefinitely, it is better to keep them constantly frozen at 0 degrees Fahrenheit at all times, and when walnuts are bad, they will have a bitter taste, and they can also develop an odor. When molds appear, they should be thrown away for sure.
