About 3 months, according to USDA FoodKeeper v128, stored as follows: cool, dry pantry away from heat and light.
Rye (flour, meal) is shelf-stable at room temperature: cool, dry pantry away from heat and light. Refrigerating it mainly preserves quality rather than safety.
Look for: A rancid, paint-like, or musty smell; Clumping, or moisture in something that should be dry; Insects, webbing, or larvae in the package; Faded colour or a lost aroma. Those are the general signs for baking & cooking — USDA FoodKeeper v128 publishes no spoilage note for Rye (flour, meal) specifically. Never taste something to test it — when in doubt, throw it out.
Yes — USDA FoodKeeper v128 gives about 6 months in the freezer at 0°F (−18°C). Frozen food stays safe indefinitely; that window is about quality, not safety.
