In this study, La Rioja wine terroir was investigated by the use of (1)H NMR metabolomics on must and wine samples. Rioja is a small wine region in central northern Spain which can geographically be divided into three subareas (Rioja Alta, Rioja Baja, and Rioja Alavesa). The winemaking process from must, through alcoholic and malolactic fermentation, was followed by NMR metabolomics and chemometrics of nine wineries in the Rioja subareas (terroirs). Application of interval extended canonical variate analysis (iECVA) showed discriminative power between wineries which are geographically very close. Isopentanol and isobutanol compounds were found to be key biomarkers for this differentiation.
本研究采用（1）H NMR 代谢组学方法研究了拉里奥哈葡萄酒风土。拉里奥哈是西班牙中北部的一个小葡萄酒产区，在地理上可分为三个次区域（里奥哈高地、里奥哈巴哈和里奥哈阿拉韦萨）。本研究从葡萄汁开始，通过酒精发酵和苹果酸-乳酸发酵，对九个酒庄的葡萄酒进行了 NMR 代谢组学和化学计量学研究。区间扩展典型变量分析（iECVA）的应用显示了地理位置非常接近的酒庄之间的区分能力。异戊醇和异丁醇化合物被发现是这种分化的关键生物标志物。
