Shelf life of rice bran?

Anyone know what the shelf life of unopened bag of rice bran is? Does it go bad?

Should be good for a long time as long as it’s kept dry.

It will get weevils but the deer don't care.

Speaking of rice bran I just got a bag of the peanut butter flavor to try after I had been feeding plain. Should it have a berry flavored smell? I know theres a berry flavor but my bag clearly says peanut butter. Just curious on the smell.
