Connection is protection
I prep for a few yrs out....some things do not taste right after a few yrs I don't care how much mylar or vacuum sealing you do although that helps..flour gets a funny taste after a couple of yrs...I know..buy wheat berries..you do have to use them up pretty quickly after grinding.
the things I do store are in canning jars...I probably have too much.
don't drive yourself crazy.
