Last fall I contributed to the Kickstarter campaign by Steve De Long for his Wine Maps of the World box set. I received them about a month ago and love them. I reference them regularly when I'm opening wine, ordering wine, etc.
They have an excellent level of detail (take a look at the screen shots of the individual maps on the website) but where they fall short is when it comes to the individual vineyards of each region. It would be impossible to include, say, all the climats in Burgundy on a map of this scale.
Here are the other maps I have so far:
Barolo/Barbaresco: Alessandro Masnaghetti's Enogea app and digital maps for Barolo, as well as his three books for Barolo and Barbaresco. They're hard to beat.
Champagne: Peter Liem's book which includes excellent maps.
Bordeaux: I've ordered Jane Anson's new book which is supposed to have high quality maps of the region.
I'd love to have more detailed maps of Burgundy, the other regions of Italy (especially Tuscany), Spain, and the US west coast.
So my question is: what are your favourite wine maps for each wine region?
