In response to a suit brought by Italian Parmesan producers in the European Court of Justice against Germany for allowing German companies to make and sell "Parmesan" cheese, the German government argued that the word "Parmesan" is generic and that any cheese that is intended to be grated and put on pasta could be so named. That seems like a pretty lame defense and the court agreed.
So the Italians won and now nobody in the EU can market any cheese as "Parmesan" unless it is produce in Italy by the "Parmigiano-Reggiano Cheese Consortium."
So now it seems that anyone in the EU who wants to make cheese that looks like Parmesan, and is used like Parmesan, and that maybe even tastes like Parmesan but is not made in the region of Parma, has to call it something else.
My vote is for Parma-John (or Parma-Jack) after my paternal grandfather whose name was Giovanni and who hailed from Borgo Val di Taro in the province of Parma.
