Identification of Sensory and Voltammetric Markers of Regional Typicality: Tempranillo Rioja Wines as a Case Study

Résumé

The definition of regional typicality is a determinant for the preservation of perceived wine quality and protection of wine origin. This work firstly aims at evaluating the sensory diversity of young Tempranillo Tinto wines in the three subregions of DOCa Rioja (Alta-RALT-, Alavesa-RAVS- and Oriental-RO-) and secondly aims to explore the capacity of voltammetric signals to measure sensory differences. Thirty young Tempranillo Tinto wines, ten from each subregion, were sensory-described using a free sorting task followed by a free description task with 32 well-established Rioja winemakers. The sorting task evidenced that the salient sensory differences perceived were between RO and RALT/RAVS, attributed to differences in perceived colour intensity, body/structure and liquorice aroma. The free description task highlighted the core and shared characteristic of the young Tempranillo Tinto Rioja wines, a fresh fruit aroma, but also the unique and specific sensory profiles attached to the three regions. The RALT region presents ripe fruit and spicy and balsamic/mint aromas with powerful tannins, while RAVS’s wines are mainly characterised by their gummy candy, fresh fruit, lactic and floral aromas, with a silky and mellow mouthfeel. The characteristic profile for RO was linked to jammy fruit, with spicy aromas and a light perception in the mouth. The signals derived from linear sweep voltammetry were able to measure the main sensory differences between RO and RALT/RALV, as did the sorting task. This is the first time that scientific research has established the typical regional character of young Tempranillo Tinto Rioja wines, which includes a common and shared profile combined with the specificities linked to each subregion, contributing to a better understanding of the notion of regional typicality in wine.
