I have canned items to last for many months. Many have expiration dates for over 3 years out. We just use older cans and replace with new purchases to stay stocked up.
Can’t most canned goods be eaten a few years past the expiration date if kept cool?
I ate mine down last year, just to see... never bought anything all winter except produce and junk food... Made it to summer, but I broke my knee and went another 8 weeks. So about 7 months and still could have gone a bit more, maybe 2 more months... but things were getting pretty inventive.
It's a good exercise. I sure found out some stuff I should have had more of, and my rotation has been adjusted on some stuff - about 1/4th of my canned meat turned out to be a little rank... but the pup sure liked it fine. Handy to figger that out before I needed it.
So long as I can be in my cabin, winter really isn't a bother, unless I have to dig out the windows. Other than that chore, all my shovels have motors... : )
