Ribera del Cuarzo Clásico is all precision and finesse - a pure note of blue-black fruit, sweet cream and rising dough fills the room when a glass is poured. As the wine opens up, green pinecones, sticky with sap, juicy cherries, vivid purple bilberries and fat clusters of blue-bloomed black grapes. With an evocative violet character, and hints of liquorice and cedary pencil shavings, this has an elegance that echoes cru classé Médoc Bordeaux: an impression underscored by its lithe, fine-boned structure. An exquisite wine, this will impress now and should develop beautifully with bottle age. This is the produce of eight vineyards, which together showcase the diversity of the classic area of the Río Negro valley.
