After goin on 7 tours, I'm sick of the lame excuses given for why so many higher proof bourbons are "export only" and American's can't get their paws on them, unless of course you go to Japan and fork out $100+ for them.

Why? Why aren't these available, even in small quantities? There simply must be a thorough answer to this question. And not the seemingly naive and innocent "it's the marketing people" reply that the tour guides gave me this week. There are reasons behind it... so what are they?
