I did a search but couldn't find an answer to my question. In my quest for a bottle of the Elijah Craig barrel proof I read somewhere that it was something like 134 proof. It got me wondering how some barrel proof bourbons can reach proofs higher than 125. I mean if legally it must be put into barrels for aging at not more than 125 proof how does the finished product have a higher alcohol content? I'm assuming it has something to do with evaporation/"angels share" etc. but I would logically think that the alcohol would evaporate before the water does which should result in a lower proof than what it was put in at. Anybody have an answer to this question?
