If you're a baker, there's nothing worse than going to your pantry and finding flour that's gone rancid. When you open bags of flour at home, it's a smart practice to transfer the contents out of the bag and into an airtight container and store it in the freezer. According to the Wheat Foods Council, flour can last indefinitely if frozen. If you don't have room in your freezer and need to keep it in the fridge instead, your flour can stay fresh there for a whole two years.
