A comparison of the volatile and phenolic compositions of Muscat of Bornova wines from two different terroirs in the Aegean region of Turkey

Abstract This study investigated the aromatic and phenolic compositions of two different Muscat of Bornova wines from two distinct terroirs (İzmir and Manisa) and compared them to basic terroir properties over the course of two consecutive years. The 53 volatile and 14 phenolic compounds found, were identified and quantified by GC-MS-FID and HPLC-DAD with MS, respectively. The Menderes terroir has higher amounts of terpene and C6 compounds which are varietal aroma compounds. The total phenolic content in the Menderes terroir is higher than in the Kemaliye terroir. Trans-caftaric acid was the most abundant phenolic compound According to the statistical results, most of the compounds were affected by both vintage and terroir; however, the effect of vintage seems to be more significant.

摘要 本研究针对源自两个不同风土（Terroir）产区（伊兹密尔İzmir与马尼萨Manisa）的两款博尔诺瓦麝香（Muscat of Bornova）葡萄酒，分析其香气组分与酚类物质组成，并连续两年开展跟踪监测，结合基础风土特性展开对比分析。共鉴定并定量检出53种挥发性成分与14种酚类物质，分别采用气相色谱-质谱-火焰离子化检测器（GC-MS-FID）与高效液相色谱-二极管阵列检测器-质谱联用法（HPLC-DAD-MS）完成检测。门德莱斯（Menderes）风土产区的萜烯类与C6化合物（均为品种特征香气物质）含量更高，其总酚含量亦高于凯马利耶（Kemaliye）风土产区。反式咖啡酒石酸（Trans-caftaric acid）是丰度最高的酚类化合物。统计分析结果显示，多数被测成分同时受酿酒年份与风土的影响，但酿酒年份的影响更为显著。
