Opened a 8 year old can today. Still edible, no significant change in ph, color or other condition which might signal it having gone bad. The taste had noticeably degraded though. Since a chemical variation has to take place for a change in taste, I can only assume it's on its last leg for viability.
Temperature range was 68-74F with one spike up to 89F for one day when the air conditioning went out. This was meant to be the control for other extremes.
In excess of 90F for 4 months makes them inedible. 6 out of 6 cans experienced this.
Any point below 25F freezes it. It seems to experience sublimation when it comes back up above freezing. Contents were inedible within a week of this. Not every can did this. Out of 6 cans tested, four failed, two had no change.
Anywhere between 35F and 80F seem to maintain product integrity with 72F being ideal pending opening two more control cans. I am not expecting any change.
Giving it a safety factor of a year, rotation should be on 7 year cycles at those temps.
FYI
