The white Marsanne grape is widely planted in France's northern Rhône region, and is the main component in white Hermitage, St-Joseph, and Crozes-Hermitage. It's also increasingly available as a vin de pays wine. The grape makes rich, nutty, herby, full-bodied wines with great aging potential. It's also planted in Switzerland, the U.S., and Australia, which has some of the world's oldest Marsanne vineyards.
