Separate freezer≤-18ºC (0ºF)6 to 12 months Store milk toward the back of the freezer
These recommendations are for quality only. Foods are kept safe almost indefinitely in the freezer.19 20

Some things to consider when navigating optimal versus acceptable storage times:

  • The temperature of the room matters. If the surrounding temperature is on the higher end, consider the lower length of the referenced time. If the surrounding temperature is low, consider the higher length of the suggested storage time.
  • When storing in a refrigerator, placing items in the door versus the back, and whether a refrigerator is opened often or not also matter when it comes to consistency of temperature.
  • These temperatures are for freshly expressed and refrigerated milk. Previously frozen milk spoils faster since it lacks some of the properties of fresh or refrigerated milk.
