Although not a pure play this wine contains Chardonnay and "Yellow Wine" made from the Savagnin grape (don't confuse it with Sauvignon) . It is called Vin Jaune and comes a small wine region in eastern France called the Jura. I found out about this grape back in 1998 and never thought I would get a chance to try it.
This grape is the specialty of the Jura and is grown almost no where else (although ironically it is grown in Ontario)
