Hi, I'm Italian and I'm a wine lover 
Your map is very beautiful, but from a geographic and cartographic point of view, and also from a wine production point of view is really very general and not precise. The labels close to the colored areas seem to match the names of our administrative regions (are your sure that french word for "Veneto" is "Venetie"?), but don't give a correct idea of the placement of the region and its bondary. While, if we consider the names as names of "wines areas", I don't understand well why you get separated "blobs" inside the regions. For istance, why three red blobs separated by a non-wine area in Emilia-Romagna? And why all these sparse blobs in Lombardia or Lazio? Or why the Friuli-Venezia-Giulia doesn't reach the border of the country? And why Veneto is splitted in two?
It's not very clear to understand. Consider also that Tuscany and Emilia-Romagna are in great part the same kind of cultivar (Sangiovese, that is a component of Chianti and of Brunello).
Anyway, from a graphical point of view is really a beautiful map.
My two cents

Thanks Marco.
Firstly, this is the reference I've got for the job (it's the first of 26 maps for the book):

Of course, each blob represents a different appellation. The eastern blob of Veneto (yes, it's Vénétie in French), could have been labeled Piave but it's still a wine from Veneto.
I don't know how it's presented elsewhere, but here - in Quebec - where wine and liquors are sold by a state agency, wine is placed in the store by country... well, except for France because it's like 60% of the choice we have. All the Italian wine is the "Italy" rack...
If I take the example of French wine, we have a Bordeaux section, a Languedoc one, a Burgundy one, etc. It's classified by greater region. We don't have Chablis, Medoc or Saint-Chinian separately. Since the book is primarily targeted for local market, that may explain the choice (maybe... the manuscript is almost done and they just contacted me).
Having said that, I'll have a map of Burgundy and another of Languedoc with the different appellations of the different wines made there. I just don't have one to do for Italy.

I'll have to do 12 maps on French wine on 26...
As I remember my last trip to Total Wine in Florida (and the amount of drool it produce before all that choice!

), wine where presented by varieties. An alley of Cabernet and an other for Pinot noir, ... Drawing a map of where you can find Sangiovese is not impossible, but Cabernet and Pinot aren't grown only in one region.
I'd love to make a map like that one:

Honestly, I understand your point 100% but I have very little to say in the choice of what to map...

And since the public are people who know nothing or not much on wine, it could be too much to enter that level of detail (which would not be that detailed, I give you that). I know a lot of people who would just be surprised to see that there's wine made in South Africa or Austria...
