Do beer bottles explode in freezer? I have had cola cans explode in my freezer. But I cannot afford to test this on my long neck beer bottles.

Do beer bottles (or cans) explode in a freezer (of a typical fridge in a household) ?
Yes, they will.   Given beer is (generally speaking) more than 90% water, and water expands when frozen, beer will make a mess of your freezer if left in there too long.  The bottles themselves don't tend to break, in my experience, but the cap seals fail and the beer will leak out everywhere.
