Greg,
Once or twice a week we do blind tastings of other producers wines from all over Germany. It is surprisingly simple to nail-down wines from different villages if not individual vineyards. We might not be able to say Pechstein or Kirchenstück, but BASALT is very easy to get. I don’t think anyone would mistake a Pfalz wine for a Mosel or Rheingau. Even more to the point, it is pretty easy to pick out Wachenheim, Forst, Haardt, or Deidesheim wines –all of which lie within about 10 km of each other. Hardly any of them show any petrol characteristics. We have such an incredible array of terroir here and a few vineyards with absolutely individual personalities –Forster Kirchenstück & Pechstein, Birkweiler Kastanienbusch, Burrweiler Schäwer, and Haardter Burgergarten to name just a couple. Sure, naming Graacher Domprobst from Himmelreich is more difficult given that they are both slate, but Riesling absolutely shows very wide differences depending on where it is grown.
Cheers,
Bill
