Flour lasts basically indefinitely in a deep freezer. I just emptied out the last bits of a bag bought during covid and it was fine.

This is in food grade air tight sealed buckets so ymmv.

Who wants to waste freezer space with 40 lbs of flour? Pretty bad use unless, again, you love baking or don’t have a use for it.

Also, most flour lasts well past the 12 month expiration just fine. Barely a need to freeze it.
