For long term storage, I put the grains in a plastic bottle and add a piece of dry ice, the dry ice ejects the oxygen. In this way the grain lasts forever. I have bottles here since 2010, they are all perfect. I have beans, rice, corn, and others. I do the same with popcorn and the popcorn is perfect, like fresh grains. Have lots of corn, so you can have chickens and eggs.
