Q&A: How Will I Know if My Milk Is Spoiled?
Just like any sort of milk, you can tell it’s bad when it stinks. (And if you still aren’t sure, you can always taste a few drops.) As a general rule, frozen milk will stay good in a chest-style deep freezer for six months to a year; in a freezer attached to a refrigerator (with a separate door) for three to six months or in a freezer compartment inside a refrigerator for up to two weeks.
