Wine region maps
Wine Spectator published some terrific illustrated wine region maps. The free PDF's cover Argentina, Australia, Austria, Chile, France, Germany, Italy, New Zealand, Portugal, South Africa, Spain and the United States.
Oddly, the only regions covered in the US are California, Oregon and Washington. No New York, no Texas.
Still, these are an excellent resource for learning about wines, regions and appellations.
