As a side note, the explosion in terroirs from the new world has really (seems to have) made the notion of wine snobbery somewhat archaic. In the 19/20th century perhaps it was a mark of distinction, to put some investment in this. The math is far more dauting to have an encyclopaedic understanding of the field than it was in, say 1930. The growth of new areas, new techniques, and the everchaning weather has made this a fools errand, and a false class marker at best.
