How long does an open jar of wheat germ last?

An open jar of wheat germ typically lasts about 3 to 6 months when stored in the refrigerator to maintain its freshness and prevent rancidity. If kept in a cool, dark place, it may last only a few weeks. Always check for any off smells or unusual changes in texture before use, as these can indicate spoilage. For best quality, it's advisable to use it within the recommended time frame.
