Viognier is thought to be an indigenous grape of Croatia that was brought to the Rhone in France by the Romans. A fun story that may or not be true is that it was intended for Burgundy, to Beaujolais, and was packaged with Syrah vines that were intercepted by the Medieval French equivalent of the Jesse James gang around Condrieu in Rhone and there it stayed. http://www.snooth.com/varietal/viognier/
GAMAY Grapes grow especially well in the Beaujolais district of France where they are used to produce Beaujolais wines. Although the Gamay grape itself has lots of tannins, the resulting Gamay wines are characterized by fairly low tannins. Wines made from Gamay grapes have fresh, fruity flavors like strawberry and raspberry and aromas of pears.
nebbiolo grape variety While the first historical reference to Nebbiolo dates back to the Thirteenth Century, near Turin, some feel that Nebbiolo was known to the Romans. Nebbiolo occurs most often in the Piedmont region of northwestern Italy. Its name is thought to derive from the fog that often occurs during the growing season. Nebbiolo’s finest wines, many would say Italy’s finest reds, Barolo and Barbaresco, are grown in this area.
