Tips
  • Butter that has been continuously refrigerated will usually keep for about one month after the "sell by" date on the package.
  • If butter develops an off odor, flavor or appearance, it should be discarded.
  • Butter may be left at room temperature for 1-2 days, but it will begin to spoil rapidly if not refrigerated after that.
  • Do not store butter in the molded butter compartment of the refrigerator door for more than one week — butter will keep much longer when stored in the main body of the refrigerator.
  • To freeze butter, wrap tightly in heavy-duty aluminum foil or plastic freezer wrap, or place inside a heavy-duty freezer bag.
  • Frozen salted butter will generally keep longer (up to 9 months for best quality) than unsalted butter (5-6 months for best quality).
  • Freezer time shown is for best quality only — foods kept constantly frozen at 0° F will keep safe indefinitely.
