This map was almost as difficult to produce as our Wine Map of Italy. There weren’t bribes to paid to shady men in funny hats or anything like that but four different countries with different rules and agencies made it much harder than imagined.
Chile is well documented and straight-forward as you might expect in a exporting powerhouse. Brazil and Uruguay are also fairly straight-forward but some digging through their wine laws was essential to provide more detail. Argentina was just confounding. The Wines of Argentina publishes maps that are somewhat accurate but also somewhat vague, mislabeled, with some regions in the wrong place and some using non-standard names. For example, Uco Valley center isn’t a region – it’s actually called Tunuyán. This is just one of many. When I asked them about this, they were very friendly and a little defensive. Hopefully they’ll revamp their maps in the future. Especially since the internet easily facilitates the bobbling head repetition of errors and misinformation.
