Dunno how that happened. One of Coors selling points was it was kept under refrigeration and they didn't put any preservatives in their beer. Case in point, when I left the Panhandle and moved to Houston (1970), Coors distribution pretty much stopped around I-20. Told Mother to bring me a couple cases when she came to visit. Was extremely pi$$ed when the first one I cracked open smelled like rotten eggs. Both cases were that way. Mother told me she bought them at a liquor store where they were not in the cooler.
