This paper presents a detailed review of the use of Sr/Sr isotope systematics for wine provenance studies. The method is based on the principle that the Sr isotope ratio in wine reflects that of the labile fraction of the vineyard soil from which the wine is produced. The review encompasses Sr/Sr data from wine samples published between 1993 and 2021 from terroirs in 22 different countries. The analytical procedures and techniques adopted by the different authors and the range of isotope ratios obtained in the different studies are discussed and evaluated. This study provides a bibliometric analysis of the Sr/Sr isotope approach for wine authentication at different scales. Although limitations are evident when implemented at large (global) scales, we demonstrate that the Sr/Sr isotope tracing technique remains a powerful and reliable tool for determining the geographical origin of wine when combined with detailed knowledge of the geological and soil characteristics of the substrata. For example, this combination of data allows the wines grown in the volcanic soils of Central and Southern Italy to be unambiguously fingerprinted. We present a detailed protocol for the application of the Sr isotope technique to wine authentication.
本文详细综述了锶/锶同位素体系在葡萄酒产地研究中的应用。该方法基于这样一个原理：葡萄酒中的锶同位素比值反映了酿造该葡萄酒的葡萄园土壤中不稳定部分的锶同位素比值。该综述涵盖了1993年至2021年间发表的来自22个不同国家风土的葡萄酒样本的锶/锶数据。讨论并评估了不同作者采用的分析程序和技术以及不同研究中获得的同位素比值范围。本研究对不同尺度下用于葡萄酒认证的锶/锶同位素方法进行了文献计量分析。尽管在大规模（全球）应用时局限性明显，但我们证明，当结合对底层地质和土壤特征的详细了解时，锶/锶同位素追踪技术仍然是确定葡萄酒地理来源的强大而可靠的工具。例如，这些数据的结合使得意大利中部和南部火山土壤中种植的葡萄酒能够被明确地指纹识别。我们提出了将锶同位素技术应用于葡萄酒认证的详细方案。
