Negroamaro is an autochthonous wine grape variety of Southern Italy, which is becoming very important for the Italian wine market. The wine aroma is primary affected by the chemical composition of grapes, which can be influenced also by agronomic practices such as soil management. In this study, the free and bound aroma characterization was performed by gas chromatography-mass spectrometry analyses, and the influence of two soil managements (cover cropping and soil tillage) was evaluated. A total of 40 volatile compounds were observed in the wine samples. Alcohols (55.7 mg/L), fatty acids (7.0 mg/L) and esters (6.6 mg/L) were found as the main classes in Negroamaro wine. The results showed that the aroma composition of Negroamaro wine was positively affected by soil tillage probably because of the higher water stress (ψ(s)) recorded in the vines from this treatment. Indeed, among the free volatile compounds, higher contents of esters, carboxylic acids, alcohols, phenolics and acetamides together with lower contents of sulfurs compounds were found in soil tillage wine. Conversely, no difference was observed in glycoside volatile compounds.
黑珍珠（Negroamaro）是意大利南部的一种本土酿酒葡萄品种，它对意大利葡萄酒市场变得越来越重要。葡萄酒的香气主要受葡萄的化学成分影响，而这些化学成分也会受到农业管理措施（如土壤管理）的影响。在这项研究中，通过气相色谱-质谱分析对游离和结合香气特征进行了研究，并评估了两种土壤管理措施（覆盖作物和土壤耕作）的影响。在葡萄酒样品中观察到了 40 种挥发性化合物。在黑珍珠葡萄酒中，醇类（55.7mg/L）、脂肪酸（7.0mg/L）和酯类（6.6mg/L）被发现是主要的成分。结果表明，黑珍珠葡萄酒的香气组成受到土壤耕作的积极影响，可能是因为这种处理方式下葡萄藤的水分胁迫（ψ(s)）更高。事实上，在游离挥发性化合物中，酯类、羧酸类、醇类、酚类和乙酰胺类的含量较高，而含硫化合物的含量较低，而糖苷类挥发性化合物则没有差异。
