When I read your articles, I realize about halfway through that I couldn't possibly debate this with you. You have totally different perceptions of the world. All this classism is cliche', not reality. Sure, there maybe be extreme examples of high-brow wine sippers and "yabbos", but in reality they are about as relavant as the furthest extremes of Left and Right.
Another good example to add to your list is Paris Hilton. If you go by your classist definitions, she'd be a Shiraz sipper. In reality, though, the globe goes all the way around and begins again. Most "sippers" are useless dependants just like any welfare leech. They just get their checks from different places. We don't respect them, they are just a different flavor of Jerry Springer freak. You can't class them the same as you class, say, a hard-working industrialist millionaire. Sociologically they will behave, AND BE PERCEIVED, in totally different ways.
If I had any advice, it would be to stop looking at things with these cemented classes. Pull out all the little divisions you have in your philosophy, mix everyone up, and let them settle where they may. I think you'll be surprised to find the pool offers you different striations based on different issues. Factor in, say, waste, or charitable contribution, moral imposition, etc., you might find the lines marking the classes shift.
