It's all canned, except the bacon which I chuck into the freezer in its original package. The canned meat all came from Aldi, Costco, or Walmart. I try to eat a can or two of that a week just to make sure I never have anything more than about 6 years old. Due to cost reasons I only increased my storage of that to a year. I can't determine any taste degradation at 6 years. The oldest frozen bacon I ever ate was 4 years, but the taste and texture was still good.

I did can the wheat and rice myself, because I only eat basmati rice due to the lower glycemic index and the wheat I get an organic variety from Oregon due to pesticide and GMO concerns. Yes, the manual canner is not cheap. I also use oxygen absorbers. Mylar bags are quite cost and labor effective, but I enjoy not having to worry about mice or rats, and I think long term the cans are a better oxygen barrier, so cans it is.

Due to the added cost of cans and oxygen absorbers I don't regularly eat the food I can except once a year to verify my process works and is keeping things fresh and bug free. Canned in that way I have zero doubts it will last 25 years or more. My oldest self-canned items are 6 years old now.
