I have a tiny cabin and a storage shed on land where I don't yet live full-time. I get out there once or twice a month in the warmer months, but it is in the mountains and is virtually inacessible for several months in the winter. There is no heat, water, or electricity out there yet.
I've been slowly stocking it with tools and supplies and was doing great this year until I realized that I'd stocked many items in "tin" cans. Hmm. Cans... freezing temperatures. I'm thinking maybe this is not a good idea.
I tried an experiment at home, putting a can of green beans in my freezer to see what would happen. It came out OK. However, I'm not sure I want to risk a few hundred dollars of "wet" canned food over the winter.
Does anyone have opinions, insight, advice, or experience with canned food storage in freezing temperatures?
Courtesy and compassion are the cornerstones of civilization; without them, we are not truly human.
i wouldn't worry about it... i worked in very remote spots in the high arctic and we often ate canned food that had been left in caches after expeditions on previous summers...there might be more freeze thaw cycles where your cabin is, not sure if that would make much difference... up there it was a very very long dark deepfreeze of a winter..these were regular commercial canned foodstuffs, some of it had been up there for a couple of years anyway...
anyway nobody died from it, and for the most part it wasn't noticeable...some stuff had separated a bit and needed to be stirred together, and the condensed milk gets a bit weird but that was what was available to eat and it worked.
i would be wary of any cans that got too rusty...if the seal gets compromised you could give yourself a good case of something nasty...one thing about the far north is that there isn't as great a variety of microbes to get into things
