Authorities from the Spanish winemaking region of Rioja have gone to court in Argentina to try and stop winemakers in the country from labelling their wines Rioja, the Spanish press said today.

Argentine winemakers from the region of Famatania Valley still use the word Rioja to label their wines after a region of the same name in the area.

Though Spanish Rioja producers have had the legal backing of the European Commission in the past, they have never been able to get the backing of the Argentinian government for the exclusive use of the name.
