Place the wrapped butter in a freezer bag. For freshness, do not remove the butter from its original waxed wrapping, and be sure that the bag is a zip-top freezer bag. Regular zip-top bags are not meant to keep food fresh in the freezer. In the refrigerator, butter can be safely stored for up to one month. Consult the package for its sell-by date, but be aware that the Western Dairy Association says dairy products can stay good up to one week or longer after the sell-by date. Butter can be left out on the counter for one to two days before spoiling.
