In this study, we investigate the combined use of Sr-isotope ratios (⁸⁷Sr/⁸⁶Sr) and multielemental composition to assess the geographical traceability of wines from the Ribera del Duero Protected Denomination of Origin (PDO), located along the Duero River basin on the northern Iberian Plateau. In 2025, this PDO produced around 1 million hL of high quality internationally recognized wines. The region exhibits a marked geological gradient over ~120 km, transitioning from eastern domains dominated by clay, sand, and lacustrine limestones to western sectors characterized by extensive limestone formations. Several wine samples from different wineries and representative grape varieties from Ribera del Duero were analyzed. Major and selected trace elements were determined by ICP-OES and ICP-MS, while ⁸⁷Sr/⁸⁶Sr ratios were measured using MC-ICP-MS. Multivariate statistical analyses, including Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA), were applied to evaluate the discriminating power of the combined geochemical dataset.

The results show that ⁸⁷Sr/⁸⁶Sr ratios range between 0.7090 and 0.7097, reflecting the regional geological background but providing limited resolution when considered alone. In contrast, the integration of Sr-isotope data with elemental composition significantly improves the differentiation of wine samples according to their geographical origin. Multivariate models reveal coherent groupings that correspond to geological variability within the PDO area.
