Butter

Unopened or Opened: One month after sell-by date on package in the refrigerator or six to nine months in the freezer.

Butter may be left at room temperature for one to two days, but it will begin to spoil quickly after that if not refrigerated. Salted butter will generally freeze better than unsalted butter. If it develops an off color, odor or appearance, discard it.
