Shelf Life Tips

  • How long does ground coffee last once opened? The precise answer depends to a large extent on storage conditions - store in cool, dry area and keep package tightly sealed at all times.
  • To maximize the shelf life of ground coffee after opening, transfer the ground coffee to a canister that blocks out light and has an airtight seal.
  • How long does ground coffee last at room temperature? Properly stored, an opened package of ground coffee will generally stay at best quality for about 1 to 2 weeks at room temperature, assuming it has been properly stored.
  • Should ground coffee be stored in the fridge? No, you should not refrigerate ground coffee, as the temperature fluctuations will affect the taste and flavor of the coffee.
  • Should you freeze ground coffee? Frozen ground coffee may lose some of its flavor, so freezing is recommended only for coffee that cannot be used up within two weeks of opening the package.
  • Freeze ground coffee in tightly sealed original package or place inside covered airtight container.
  • How long does ground coffee last in the freezer? Properly stored, it will maintain best quality for about 1 month, but will remain safe beyond that time.
  • The freezer time shown is for best quality only - ground coffee that has been kept constantly frozen at 0°F will keep safe indefinitely.
  • How can you tell if ground coffee is bad or spoiled? Ground coffee typically loses flavor over time and develops a stale taste - if coffee develops an off odor, flavor or appearance, it should be discarded for quality purposes; if mold appears, discard the ground coffee.
