Shelf Life Tips
- How long do frozen blackberries last? The precise answer to that question depends to a large extent on storage conditions - keep blackberries frozen at all times.
-
Properly stored, frozen blackberries will maintain best quality for about 12 months in the freezer, although they will usually remain safe to eat after that.
-
Are frozen blackberries safe to eat after the “expiration” date on the package? Yes, if properly stored - commercially frozen blackberries will typically carry a Best By, Best if Used By, Best Before, or Best When Used By date but this is not a safety date, it is the manufacturer's estimate of how long the frozen blackberries will remain at peak quality.
-
How long will frozen blackberries remain safe to eat? Frozen blackberries that have been kept constantly frozen at 0°F will keep safe indefinitely, as long as they have been stored properly and the package is not damaged.
-
How to tell if frozen blackberries are no longer good? If dry spots or discolorations have developed on the frozen blackberries, freezer burn has begun to set in - this will not make the frozen blackberries unsafe to eat, but it will harm the texture and taste.
