Two Five gallon containers of Emergency Essentials emergency food supply. These were purchased in 2012 and have been stored in a celaar ever since. The website says these are good for 25 years. I have one labeled "Black beans" and one labeled "Kidney beans" . These are packed without oxygen and as far as I can tell have never been opened. They are very heavy. This company is still in business and selling the same tyoe of products, but in smaller containers now, (I assume shipping these got really expensive) see  https://www.beprepared.com/pages/frequently-asked-questions
