Riesling by John Spottiswood.

If made in Germany or Alsace, a Riesling is a very good, somewhat sweet white wine. If made in America, it's usually a so-so white wine that's usually made from Sylvaner = Franken Riesling, Gray Riesling and Emerald Riesling grapes, mediocre varieties which coast on the reputation of their superior relative, Johanissberg Riesling.
