Grape aromatic characteristics are very important for producing quality wines. There have been very few studies on concentrations of volatile compounds in grape berries from vines with cover crops. For this reason, the aim of this work was to evaluate the influence of "Zulla" cover crop on the volatile profiles of organically grown Syrah variety grapes. For this purpose, volatile profiles of grapes obtained from vines with three different amounts of cover crop (one line, two lines, and four lines) and without cover crop, over three harvests (2019, 2020, and 2021) were determined. Moreover, a comparative study of conventional and organic crops, both submitted to soil tillage, was performed. The grape samples came from a warm climate zone. Must volatile compounds were determined by sequential sorptive extraction with Twisters by immersion (SBSE) and headspace (HSSE), followed by GC-MS analysis. A total of 160 compounds were determined and most of them were influenced by the presence of cover crop. However, the results showed an important influence of the harvest year over agronomic practices. Therefore, organic cultivation using Zulla cover crop seems to be a suitable tool for the implementation of friendly ecosystem management in a warm climate Syrah vineyard.
葡萄的香气特征对于生产优质葡萄酒非常重要。目前，关于覆盖作物葡萄浆果中挥发性化合物浓度的研究非常少。因此，本研究的目的是评估“Zulla”覆盖作物对有机种植的西拉品种葡萄挥发性特征的影响。为此，在三个不同覆盖作物量（一行、两行和四行）和无覆盖作物的条件下，对来自葡萄藤的葡萄的挥发性特征进行了三次收获（2019 年、2020 年和 2021 年）的测定。此外，对常规和有机作物进行了比较研究，两者都进行了土壤耕作。葡萄样品来自温暖气候区。采用 Twisters 连续吸附萃取（SBSE）和顶空（HSSE）法测定了酒样中的挥发性化合物，然后用 GC-MS 进行分析。共测定了 160 种化合物，其中大多数受覆盖作物的影响。然而，结果表明，收获年份对农业措施有重要影响。因此，在温暖气候的西拉葡萄园，使用“Zulla”覆盖作物进行有机栽培似乎是实施友好生态系统管理的一种合适工具。
