Temperature range for canned goods?
The question is about home canning in glass but I suspect the same applies to commercial metal cans.
I have read under 70 F and bad things happen fast at 100 F.
Is there a lower bound? If they freeze will they survive.
I want to set up an outdoor kitchen that I would use for home canning and cooking. I would like to build a cabinet for the canned goods (one reason is to keep them out of the sun). It will only get to less than freezing maybe a couple times a year and doubt they would freeze.
Is the lower bound above freezing?

I don't know that outdoors would be the best place to store your home canned goods. Even in an insulated cabinet, that the sun doesn't hit, the temperature in the cabinet may rise in the summer above recommended levels. Also, humidity may rust your lids(and bands, if you leave them on).
