Originating in the Rhone valley, Roussanne was mentioned in 1781 in a text on the wines of Hermitage. Its name refers to the red colour of the ripe grapes. DNA tests suggest that Roussanne is either a parent or an offspring of Marsanne. Ripening in mid-season, Roussanne is sensitive to wind, powdery mildew, grey mould and dust mites. In Switzerland, Roussanne is considerably less widespread than Marsanne, perhaps wrongly so when we consider the aromatic qualities and the high acidity levels of this variety, conferring a good longevity on the wines.
