Found this article. The focus was on a French winemaker selling wines that apparently aren't allowed to be sold in the European Union because they blend wines from the EU with wines from outside the EU.

Apparently one of the worries in the EU is that someone might blend really cheap wine with a smidge of a high quality wine at a high markup. The other thing (especially in France) is a strong sense of "terroir" - that the qualities of a wine really come from where the grapes were grown. And I say grown because often wineries process grapes from somewhere else. I remember visiting a winery near Seattle (Woodinville) where they processed grapes grown in Washington, but hundreds of miles away, but still from the state. There were a lot of wineries there.
