>>907127If you're going car camping you could just keep the beer in the car and heat it up with the heater if you find that it's getting really damn cold.
Or you could keep the beer close to the fire(not too close to possibly melt the can or expand the glass). Unless you're keeping the beer in a snowbank in minus 20 Celsius over night it shouldn't get to the point of completely freezing. Because of the additives in beer it has a slightly lower freezing point than water.
Another idea is to boil up some water and put your beer in the boiled water if you're worried they might be frozen.
