This project came about as a result of our concern to find out more about our indigenous grape varieties. It is a project that has been set up in coordination with the Universities of Rioja and Salamanca with the aim of studying the phenolic profile of our indigenous varieties, Tempranillo and Graciano, together with the profile of the wine during the different phases of the wine-making process. Knowledge of the phenolic profile of our varieties and our wines during the different phases of the wine-making process has helped us to use those viticultural practices and wine-making techniques that produce more structured, attractive, elegant and round wines, such has been achieved in our excellent RODA wines.
