Rioja is a wine region in Spain, where the wines are made using grapes grown in La Rioja, Navarre and Basque.
Until recently red wines were made only from Tempranillo, Garnacha tinta, Mazuelo and Graciano grapes. Maturana Tinta has recently been approved by the Regulating Council of the D.O.Ca to to be added to the authorised list.
Similarly white wines were made from Viura, Malvasía and Garnacha blanca with Chardonnay, Sauvignon blanc and Verdejo now also approved for the regions wines.
Despite these new changes, Rioja wines continue to be dominated by Tempranillo and Viura which together account for over 80% of all grapes used to make wine in the region.
