Given the choice between listening to rock critics wax endlessly on garage centric one shot wonders who emerged from Decatur suburbs and wine critics swanning about about a particular pour's pretensions, bouquet, garish aftertaste or the quality of the buzz it might give you, I would have to select the rock snobs , dreary as they might be or become after a duration.
Rock and roll began as a legitimate grass roots alternative to the ossified white pop that had a stranglehold on post-forties pop music, and it actually is the case, despite rock criticism's sloven tendency toward self-fellatio, that something honest, original and artful might come through all that energy, anger and quirkiness.
Wine, to my view, is merely a form of hooch, and the sum of my aesthetic toward it's qualitative states were whether it made me gag or if went down the gullet without a fight. Art and subtlety and self-expression had nothing to do with it--wine was for getting a buzz, getting plastered, getting terrifically fucked up. In that sense, wine appreciation is democratic because alcoholism isn't a respecter of race, class, gender, or sums of money one might have.
The salient difference between the two is that rock and roll is something that sounds good, when it is good, sober. Wine, after you quite drinking and stay sober, is just something you learn to live without and wonder how the fuck you spent so many years being wrong for so long about what a great thing spirits were to one's quality of life.
