I have a case of Hamms in my fridge! Go Vikings!
One of my uncles had bought a case of Hamm's just before he died in late 1973, and it sat in my aunt's downstairs refrigerator, with a can or two being brought upstairs when the rare visitor just had to have a beer. Sometime in the early '90's, a family event led my dad, another uncle and I to go down to the basement to sit around and reminisce; we found the remaining cans still in the 'fridge, so we opened them up to see how bad they had gone. To our surprise, it was as good (or "bad," if you weren't a Hamm's fan) as I remembered it, and we downed all but one can, which we left in place out of nostalgia.
About three years later, my aunt passed away and we cleaned the house, readying everything for the estate sale. I opened the remaining can intending to drink a toast to this couple who had done a lot for me and my family, bit I found the beer had gone very bad. If there was some sort of message to it all, I never figured it out, but I do know this much: if only one can out of that lot went bad over a 20 year period, Theo. Hamm & Co. had done one hell of a job back in the day.
