Abstract: Genetic erosion in the Spanish wine regions has increased recently. Because of this, it is necessary to preserve all these minority and local varieties which are in danger of extinction within germplasm banks. The objective of this work consists in the identification and characterization of the accessions known as ‘Tempranillo’ in Rioja appellation, in order to rationalize and develop a complete description of them. The microsatellite markers and the ampelographic description have been used for variety identification of all the accessions. The characterization of the main grape growing and enological characteristics was carried out, as well as the chemical analysis of must and wine, previous to a sensory evaluation. The existence of three different ‘Tempranillo’ varieties has been proven: ‘Tempranillo Blanco’ (white), ‘Tempranillo Royo’ (grey) and ‘Tempranillo Tinto’ (red). Moreover, the resolution of two synonymies has been clarified: ‘Tempranillo Temprano’ corresponds with ‘Portugais Bleu’ and ‘Tempranillo del Barón’ corresponds with ‘Trepat’. It has been concluded that within the enological and viticultural properties of all of these unknown minority varieties, both ‘Tempranillo Blanco’ and ‘Tempranillo Royo’ are adequate for quality white wines, while ‘Trepat’ is only adequate for young reds. Nevertheless ‘Portugais Bleu’ could be used in quality aged wines, as well as ‘Tempranillo Tinto’. Through the characterization and study of the local minority Rioja grape varieties, an important piece of the appellation history is being recovered. At the same time, this is a new area which will increase the differentiation, thus contributing to the increase in competitiveness of the local wine industry in the global market, preserving the identity of such a well known region as Rioja.
