There's nothing wrong with caring about something enough to dig in deep and see it for it's finer components. Some wine just taste like grapes and then others.... wow. -And some people may never be able to tell the difference. To some, this is just a blue painting, but you and I both know it's more than that:Really, the wine snobbery is the vestigial remnants of a local industry gone global and about to contract into local again.
From my experience, and I have a good amount of it in the world of wine, there are those that embrace and project the snobbery that you speak of and there are those that embrace the utility of such descriptions. I used to teach wine tasting classes with my pal sounds_sound to incoming servers at an upscale northern italian restaurant. We used phrases like, "herbaceous, grassy" and "soft-tannins" when describing wine. But I don't think we ever did so to be snobby but more to walk these young people, new to the world of wine in to an established pallet of descriptors. Wine is fun and the descriptors used can be fun too. I think wine is snobby when you're being introduced to it by a snob.
