Jura
This one little 50 mile packet of remote mountain-region vineyards may capture the imagination more than any other area in France. The wines don't make it to the US in any large quantities (in fact, the dedicated will often travel to France to get a taste) but when they do, fans are mesmerized. It could be the local varieties. It could be the purity of the farming. Either way, it's a delicious region that you need to experience in the glass.
