Well, you're sort of quirky yourself, you know. In a good way.
It's natural for us humans to attempt to impose some sort of hierarchy or ordination or categorical definition system for everything we come across. How should wine be any different? Trouble is, once again, wine is so subjective, so internalized, that any attempt at a categorization is individual, or at best so general and arguable and often qualified as to be essentially meaningless.
Still, it allows us to grope towards some sort of conclusions and understanding of what the hell we're all talking to each other about.
And for the record, I have no problem with categorizations of grape varieties, or even wines. What I object to is the use of the word 'noble' (versus what, ignoble?). That word carries so much inevitable freight, so much connotational weight, that it automatically puts the discussion at a disadvantage. It presupposes some sort of meritocracry through aristocracy. I know you are using it more in the sense of heritage/continuity/consistency of flavor, but it is still a loaded word that doesn't work for me.
The other problem I have is how to "rate" (and rating is, let's be frank, just another word for "points") terms like elegance, quirky, rustic. Is a well made Muscat from superior place and a superior winemaker in a superior vintage more or less "elegant" than a poorly made Petite Chateau from Bordeaux? Is a Madiran more "rustic" than a St. Joseph? And if so, why? What makes one a country bumpkin and the other an urban sophisticate?
Nah. Since you're still in that University world (for the time being) I'd have to echo at least one, if not most, of your Professors and chide you for not more carefully defining your terms. How can you make your point if you haven't defined your terms and supported your premise?
Oh, and Semillon? You could try a Hunter Valley Australian Semillon. Not a grape/style that I particularly care for, but there's lots of pundits and punters that rave about it. Conversely, there are a handful (small hand) of California Semillons you can find when you get back here. Most Semillon is still blended with SB though; you don't see it too often as a disctint variety. And maybe there is a reason for that, purported nobility nothwithstanding?
