This paper presents a novel tool for Spanish commercial wine discrimination according to their designation of origin (PDO). A total of 65 commercial wines from different Spanish designation of origin (Alicante, Bullas, Campo de Borja, Jumilla, Castilla la Mancha, Ribeiro, Ribera de Duero, Rioja, Rueda, Utiel-Requena, Valdepeñas and Valencia) were characterized. The rare earth elements (REEs) content was determined by a high-temperature torch integrated sample introduction system (hTISIS) coupled to inductively coupled plasma mass spectrometry (ICP-MS). The REE content was used to draw characteristic PDOs radar charts. Results indicated that the REEs fingerprint provides a good prospect to discriminate the different Spanish PDOs, except for Alicante, Castilla la Mancha, Jumilla, Utiel-Requena and Valdepeñas. Finally, for those PDOs that were not properly distinguished, a second fingerprint obtained from Ba, Co, Cr, Mn, Ni, Pb and V content was used for discrimination purposes.
本文提出了一种新的工具，用于根据西班牙葡萄酒的原产地名称（PDO）对其进行商业分类。总共对来自不同西班牙原产地名称（阿利坎特、布尔哈斯、博尔哈、胡米亚、卡斯蒂利亚拉曼恰、里贝拉德尔杜埃罗、里奥哈、雷乌斯、乌迭尔-雷格纳、瓦伦西亚和巴伦西亚）的 65 种商业葡萄酒进行了特征描述。采用高温火炬集成进样系统（hTISIS）与电感耦合等离子体质谱仪（ICP-MS）相结合的方法测定了稀土元素（REE）的含量。REE 含量用于绘制具有特征 PDO 的雷达图。结果表明，REE 指纹图谱为区分不同的西班牙 PDO 提供了良好的前景，除了阿利坎特、卡斯蒂利亚拉曼恰、胡米亚、乌迭尔-雷格纳和瓦伦西亚。最后，对于那些无法正确区分的 PDO，还可以使用 Ba、Co、Cr、Mn、Ni、Pb 和 V 等元素含量的第二个指纹图谱来进行区分。
