Sangiovese is the most cultivated red grape variety in Italy where it is certified for the production of several Protected Designation of Origin (PDO) wines, and it is one of the most cultivated Italian red grape varieties in California. Despite the global distribution of this variety, there is a lack of international studies on Sangiovese grapes and wines. For this reason, the present study aimed to compare 20 commercial Sangiovese wines from 2017 harvest, 9 produced in Italy (Tuscany) and 11 in California, in order to evaluate the intrinsic and perceived quality. The eligibility, identity, and style properties (the intrinsic quality) of the wines were evaluated. A group of 11 Italian experts evaluated the perceived quality by rating the typicality of the wines. The experimental data showed that the intrinsic quality of Sangiovese wine samples was affected by the growing area; in particular, the wine resulted very different for the color indices and polyphenol composition. The above differences in intrinsic quality levels did not lead to a different evaluation of the perceived quality (typicality) by the wine experts. The results evidenced that Sangiovese variety is recognizable also if grown outside its original terroir, and fresh and fruity wines were considered more typical. This study expands our current knowledge of Sangiovese wines and the contribution of regional characteristics to the composition of wine.

评估来自加利福尼亚和意大利的桑娇维塞葡萄酒的内在和感知质量。

Sangiovese是意大利种植最多的红葡萄品种，已通过认证可生产多种原产地标记（PDO）葡萄酒，并且是加利福尼亚州种植最多的意大利红葡萄品种之一。尽管该品种在全球范围内分布，但缺乏有关桑娇维塞葡萄和葡萄酒的国际研究。因此，本研究旨在比较2017年收获的20种桑娇维塞商业葡萄酒，意大利（托斯卡纳）生产的9种葡萄酒和加利福尼亚州生产的11种葡萄酒，以评估其内在质量和感知质量。对葡萄酒的资格，身份和风格属性（内在质量）进行了评估。由11名意大利专家组成的小组通过评估葡萄酒的典型性来评估感知的质量。实验数据表明，桑娇维塞葡萄酒样品的内在质量受种植面积的影响。尤其是，该葡萄酒的色指数和多酚组成差异很大。内在质量水平的上述差异并未导致葡萄酒专家对感知质量（典型性）的不同评估。结果表明，如果在其原始风土以外种植桑娇维塞葡萄，也可以识别该品种，而新鲜和果味的葡萄酒被认为更为典型。这项研究扩展了我们对桑娇维塞葡萄酒的当前知识以及区域特性对葡萄酒成分的贡献。内在质量水平的上述差异并未导致葡萄酒专家对感知质量（典型性）的不同评估。结果表明，如果在其原始风土以外种植桑娇维塞葡萄，也可以识别该品种，而新鲜和果味的葡萄酒被认为更为典型。这项研究扩展了我们对桑娇维塞葡萄酒的当前知识以及区域特性对葡萄酒成分的贡献。内在质量水平的上述差异并未导致葡萄酒专家对感知质量（典型性）的不同评估。结果表明，如果在其原始风土以外种植桑娇维塞葡萄，也可以识别该品种，而新鲜和果味的葡萄酒被认为更为典型。这项研究扩展了我们对桑娇维塞葡萄酒的当前知识以及区域特性对葡萄酒成分的贡献。
