Tips

  • How long does a package of white flour last? The precise answer depends to a large extent on storage conditions - to maximize the shelf life of white flour (all-purpose white flour) store in a cool, dry area.
  • How long does white flour last at room temperature? Properly stored, a package of white flour will generally stay at best quality for about 1 year at room temperature.
  • To maximize the shelf life of white flour once the package is opened, transfer flour to a covered airtight container or place original flour bag in a resealable plastic freezer bag.
  • Is white flour safe to use after the "expiration" date on the package? Yes, provided it is properly stored and the package is undamaged - commercially packaged white flour 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 white flour will remain at peak quality.
  • Storage time shown is for best quality only - after that, the white flour's texture, color or flavor may change, but in most cases, it will still be safe to consume if it has been stored properly, the package is undamaged, and there are no signs of spoilage (see below).
  • Can you keep white flour in the fridge or freezer? Yes, to further extend the shelf life of white flour, refrigerate or freeze it; place the white flour inside covered airtight containers or heavy-duty freezer bags.
  • How long does white flour last in the fridge? White flour will maintain best quality for about 2 years in the refrigerator.
  • How long does white flour last in the freezer? Properly stored, it will maintain best quality for about 2 years, but will remain safe beyond that time.
  • The freezer time shown is for best quality only — white flour that has been kept constantly frozen at 0° F will keep safe indefinitely.
  • How can you tell if white flour is bad or spoiled? The best way is to smell and look at the white flour: if the white flour develops an off odor, flavor or appearance, or if insects appear, it should be discarded.
