'Asprinio' is a white dry wine characteristic for its acidity and aromatic flavour, known as emerging DOP wine in Southern Italy. Nevertheless, little information is available on the metabolomic profile of this wine. Thus, in this paper we evaluated the colourimetric parameters, H NMR profiles and free amino acids content of 'Asprinio' wines, bottled by two different wineries (hereafter 'Asprinio_A' and 'Asprinio_B') collected in 2019 and 2020, using 'Greco di Tufo' for comparison. The colourimetric parameters are similar for both 'Asprinio' wines and differ from 'Greco di Tufo' wines. On the other hand, both H NMR and free amino acid content profiles show different chemometric profiles among the three wines analysed, although the profiles are similar for both vintages. Moreover, the multivariate analyses carried out highlight differences between 'Asprinio_A' and 'Asprinio_B', which exbibit also different residual yeast and plant DNA. Overall, considering that the two-manufacturing wineries use 100% 'Asprinio' grape, the difference retrieved between the two 'Asprinio' wines could be explained by the different grapevine training systems: '' (training system inherited from Etruscans) for 'Asprinio_A' and '' for 'Asprinio_B'.
“Asprinio”是一种白干葡萄酒，以其酸度和芳香风味为特色，是意大利南部新兴的法定产区葡萄酒。然而，关于这种葡萄酒的代谢组学特征的信息却很少。因此，在本文中，我们评估了2019年和2020年由两家不同酒庄瓶装的“Asprinio”葡萄酒（以下简称“Asprinio_A”和“Asprinio_B”）的比色参数、氢核磁共振谱和游离氨基酸含量，并以“图福格雷科”葡萄酒作为对照。两种“Asprinio”葡萄酒的比色参数相似，但与“图福格雷科”葡萄酒不同。另一方面，氢核磁共振谱和游离氨基酸含量谱在分析的三种葡萄酒中显示出不同的化学计量学特征，尽管两个年份的特征相似。此外，进行的多变量分析突出了“Asprinio_A”和“Asprinio_B”之间的差异，它们还表现出不同的残余酵母和植物DNA。总体而言，考虑到这两家酿酒厂都使用100%的“Asprinio”葡萄，两种“Asprinio”葡萄酒之间的差异可能是由不同的葡萄树栽培系统造成的：“Asprinio_A”采用“（从伊特鲁里亚人继承的栽培系统）”，“Asprinio_B”采用“”。
