What's the best way to store beer while camping in hot climates? 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.
I use 3 methods to store the beer, and others, while camping:


Cooler: The way you mentioned in your question.
Sunk in water: If possible, put the beer either in a plastic bag or in a hole in a nearby water body, creek or river.
In the ground: Dig a hole in the ground in a shady area and store it in there.


Second and third possibilities will keep it cool, but not really cold, depending on the area. The you can cool it even more by placing it in ice shortly before consuming it.
