• a white grape variety, now grown widely in Spain, particularly in the Rioja region (where it is often called Viura), that produces high yields of grapes that make light, fruity white wines that are high in acid. The wine does not oxidise easily in the same way as wine from some of the more traditional white Rioja grapes that it has largely displaced. This grape variety is also blended to make sparkling white wines in Spain and is grown in southern France, where it is used to produce CĂ´tes du Roussillon white wine.
