Gluten free flour is often a complex blend of various starches, grains, and fibers. Because these ingredients can be highly sensitive to moisture and air exposure, maintaining the integrity of your gluten free flour is essential for successful baking results. While it does not expire as rapidly as fresh produce, environmental factors like humidity and temperature fluctuations can degrade its texture and flavor over time. Proper storage in a cool, dry location ensures that your baked goods maintain their intended structure and prevents unwanted clumping. By monitoring the consistency and scent of your flour, you can determine if it is still suitable for use or if it has begun to age.

Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
