I bought 700 lb of crack corn for winter its in 100lb Bags . I but them in a metal cabinet to keep out squrrels and mice in the garage ,I would like to know if it will Sour? or will it be all right. thanks
It will be fine. It is dried enough to store safely that it will keep from spoiling so long as you keep it dry, and it sounds like you have it stored well.
Awhile back I bought some food grade 55 gal drums with lids and haven't had any trouble with bugs, mice or mold and they keep the corn all winter and beyond. DMc
