How Long Does Brown Rice Last in Mylar Bags?
Quick Answer: Brown rice only lasts 1-2 years in mylar bags — far shorter than white rice (25-30 years). The bran layer contains natural oils that go rancid even without oxygen. For long-term storage, choose white rice instead. Brown rice is best for 6-18 month rotation plans.

Brown Rice Storage FAQ
How long does brown rice last in mylar bags?
Brown rice only lasts 1-2 years in mylar bags, even with oxygen absorbers. The bran layer contains oils that go rancid over time. White rice lasts 25-30 years.
Why does brown rice not store as long as white?
Brown rice retains the bran and germ layers which contain 2-3% fat. These oils oxidize and go rancid within 1-2 years even in oxygen-free environments.
