Every August I go camping1 for a week or two in western PA, and I like to take along some beer to drink in the evenings. What I've been doing, to save cooler space (and reduce the amount of ice I have to replace each day), is to keep most of it out and just keep a buffer of a couple bottles in the cooler. But this question makes me wonder whether that harms the taste, because while I can control for light I can't do much about storage temperature. Should I just suck it up and put everything on ice when I get there? I haven't noticed a problem so far, but I tend to take a variety of beers (I don't drink the same thing every day) so I might never notice on my own.
1 This is not primitive camping with tiny, heat-absorbing nylon tents. Most of our tents/pavillions are canvas, and we have a small cabin available. No electricity is available, however.
