The college-level stuff is spotting the birthplace. Cabernet, yes, but French or American? Shiraz, yes, but Rhône or Barossa, or perhaps Hawke’s Bay? This is about where most of us are, most of the time. Left Bank or Right Bank is hardly postgraduate level, but if you can do Margaux/St-Julien, let alone Oakville/St Helena, you may have an MW7 in sight.
