Storing in the Refrigerator. Scoop sauerkraut into jars or freezer bags. Close the jar or bag tightly so no air can enter. Label the jar or bag with the date. Sauerkraut can stay good for up to three months in the refrigerator. Dating the bag will help you remember its age. Place the jar or freezer bag filled with sauerkraut on a shelf in your refrigerator.
Sauerkraut in its own container can last for months after it's been opened. Pork, however, tends to go bad fairly quickly even if it's been cooked. If you have leftover kraut and pork, and if the kraut has been sitting in the same container as the pork: I would try to eat it within three days after its initial preparation. By the third or fourth day, I would rather throw the leftovers out rather than risk getting ill. Biran_Sefar Â· 1 decade ago.
