It bears repeating that the judges Hodgson surveyed were no ordinary taste-testers. These were judges at California State Fair wine competition -- the oldest and most prestigious in North America. If you think you can consistently rate the "quality" of wine, it means two things:
1: No. You can't.
2. Wine-tasting is bullshit.
A 2006 study, published by the American Association of Wine Economists, found that most people can't distinguish between paté and dog food.
My personal wine Venn Diagram consists of a large outer circle labelled "something my companions thought was a good idea" enclosing smaller almost-equally-sized circles labelled "something that gives me a headache before a buzz" and "something that would be better with bubbles and OJ in it".
Also, liver-flavored butter? Who eats that on purpose?
