The coffee equivalent would be comparing coffee brewed from Arabica beans vs Robusta. And there is no way in hell any regular coffee drinker would not be able to tell the difference. :) Robusta beans are despised by every "coffee snob" in existence because of their sour and vile after taste. The coffee challenge is easier though because regular coffee only tastes either as Arabica coffee or Robusta coffee (there are some crossbreeds), but wine can taste in thousands of different ways.
