Abstract

The reproducibility of elemental profile in wines produced across vintages of 2015 and 2016 has been studied using grapes from a single scion clone of Vitis vinifera L. cv. Pinot noir. Grapevines were grown on fourteen different vineyard sites, from Oregon to southern California in the U.S.A., which span distances from approximately hundreds of meters to 1450 km, while elevations range from near sea level to nearly 500 m. The number of elements quantified in the wines made from the 2016 vintage was thirty, by using inductively coupled plasma mass spectrometry (ICP-MS). These data were compared with the twenty-seven elements quantified and previously reported in wines made from 2015 vintage, including twenty-four elements reported in both vintages. The composition of each element was analyzed by analysis of variance with main effect of vineyard. Wines were classified according to vineyard origin and environmental growing site with a combination of factors correlated with the wine elemental profile. The low variability (< 25%) of certain elements in wines from at least eight sites across both vintages, including Group 1 (Cs, K, Na and Rb), Group 2 (Ba, Ca, Mg and Sr), Group 3B (Eu), Group 13 (Al, B and Ga), Group 15 (As and P) and Co, Fe, Mn, Ni and V, demonstrated the reproducibility over the seasons analyzed (2015 and 2016). The comparison of elemental profile of wines across growing seasons demonstrates the opportunity to reproduce one key aspect of wine chemistry across vintages.

摘要

对 2015 年和 2016 年份葡萄酒中元素谱的重现性进行了研究,所用葡萄来自欧亚种黑比诺(Vitis vinifera L. cv. Pinot noir)的单个接穗无性系。葡萄藤种植在 14 个不同的葡萄园,从美国俄勒冈州到南加州,跨度从几百米到 1450 公里不等,而海拔高度从近海平面到近 500 米不等。使用电感耦合等离子体质谱法(ICP-MS)对 2016 年份葡萄酒中定量的 30 种元素进行了分析。这些数据与 2015 年份葡萄酒中定量的 27 种元素进行了比较,包括两个年份都报告的 24 种元素。用方差分析方法对每个元素的组成进行了分析,主要影响因素是葡萄园。根据葡萄园的起源和环境生长地对葡萄酒进行了分类,并结合与葡萄酒元素谱相关的因素进行了组合。至少有 8 个葡萄园在两个年份的葡萄酒中,包括第 1 组(Cs、K、Na 和 Rb)、第 2 组(Ba、Ca、Mg 和 Sr)、第 3B 组(Eu)、第 13 组(Al、B 和 Ga)、第 15 组(As 和 P)和 Co、Fe、Mn、Ni 和 V 等元素的稳定性较低(<25%),表明在分析的季节(2015 年和 2016 年)中具有重现性。对跨生长季节葡萄酒元素谱的比较表明,有机会在不同年份重现葡萄酒化学的一个关键方面。
