Well, I think some of you misinterpreted my post as being about 'chugging' high-proof liquor -- and I'm used to that. It was not, but Chuck got it -- and I'm used to that, too.
My point was, primarily, that whisk(e)y, including bourbon, isn't a natural drink for humans, whatever the proof. Virtually nobody 'likes' one's first taste of un-diluted bourbon!
But, one comes to appreciate it through practice. Practice also cultivates a sense of properties -- you come to understand what whisk(e)y/bourbon is about, and what to expect and enjoy about particular versions of it.
Thus, tasting and appreciating our native spirit is definitely an "acquired taste". You don't really 'like' it, at first, but you come to appreciate its qualities with practice and experience. The same holds true for particular brands/labels.
How is that different, really, than opera or the symphony? (Other than hangover, I mean

.)
