Marsanne is the predominant white grape variety grown in the Northern Rhône where it is used to produce white St. Joseph, Crozes-Hermitage, and Hermitage. It is a tricky grape to cultivate, being susceptible to diseases and being particularly sensitive to extreme climatic changes - if growing conditions are too cool, then it fails to ripen fully and produces thin, insipid wines, while, if too hot, the resultant wines are blowsy, overblown and out of balance.
In the Northern Rhône it tends to be blended with around 15% Rousanne and produces richly aromatic, nutty wines which age marvellously - the best examples are from Hermitage and particularly from Chapoutier. Increasingly it is being grown in the Southern Rhône and Languedoc Roussillon where it is bottled as a single varietal or blended with Roussanne, Viognier, and sometimes Chardonnay. It is also grown very successfully in Victoria in Australia where some of the world`s oldest Marsanne vines are to be found.
