Restoration works in the old Clunisian Saint-Vivant monastery in Burgundy revealed an unidentified wine bottle (SV1) dating between 1772 and 1860. Chemical evidence for SV1 origin and nature are presented here using non-targeted Fourier Transform Ion Cyclotron Resonance Mass Spectrometry and Nuclear Magnetic Resonance analyses. The SV1 chemical diversity was compared to red wines (Pinot Noir) from the Romanée Saint Vivant appellation and from six different vintages spanning from 1915 to 2009. The close metabolomic signature between SV1 and Romanée Saint Vivant wines spoke in favor of a filiation between these wines, in particular considering the Pinot noir grape variety. A further statistical comparison with up to 77 Pinot noir wines from Burgundy and vintages from nearly all the 20th century, confirmed that SV1 must have been made more than one hundred years ago. The increasing number of detected high masses and of nitrogen containing compounds with the ageing of the wine was in accordance with known ageing mechanisms. Besides, resveratrol was shown here to be preserved for more than one hundred years in wine. For the first time, the age of an old unknown wine along with its grape variety have been assessed through non-targeted metabolomic analyses.

来自古老的地下酒瓶的化学信息:用于葡萄酒考古化学的代谢组学

在勃艮第的老克鲁尼西亚圣维凡特修道院的修复工作中,发现了一个未确认的葡萄酒瓶(SV1),其年代为1772年至1860年。此处使用非目标傅里叶变换离子回旋加速器共振质谱法和核磁法提供了SV1起源和性质的化学证据。共振分析。将SV1的化学多样性与RomanéeSaint Vivant产区以及1915年至2009年的六个不同年份的红酒(黑比诺)进行了比较。SV1和RomanéeSaint Vivant酒之间的代谢密切相关特征表明,这些葡萄酒之间存在差异。 ,尤其是考虑黑皮诺葡萄品种。进一步的统计比较,包括多达77种来自勃艮第的黑比诺葡萄酒和几乎整个20世纪的葡萄酒,确认SV1一定是在一百多年前制造的。随着葡萄酒的老化,检测到的高质量和含氮化合物的数量增加,这与已知的老化机理一致。此外,这里显示白藜芦醇可以在葡萄酒中保存一百多年。通过非目标代谢组学分析,首次评估了一种未知的古老葡萄酒及其葡萄品种的年龄。
