Muscat of Bornova is a white and aromatic native grape variety of Vitis vinifera which is largely predominant in the I. zmir-Manisa province of the Aegan region. In this study, the effect of three different terroirs (Kemaliye, Halilbeyli, Menderes) located in I. zmir-Manisa province and two different years (2013-2014) on the terpene compounds of Muscat of Bornova grapes were investigated. The terpene compounds were extracted by using liquid-liquid extraction method and identified and quantified by GC-MS-FID. In 2013 vintage eighteen terpene compounds were identified and quantified. The concentration of total terpene compounds in Muscat of Bornova grapes from Menderes determined 2.1 mg/l, in Halilbeyli 1.3 mg/l and in Kemaliye 1.7 mg/l. In 2014 vintage eighteen terpene compounds were identified and quantified. In 2014 a total concentration of terpene compounds decreased in grapes from Menderes and determined 1.8 mg/L, in Halilbeyli the results were the same as the first vintage and found 1.3 mg/l and in Kemaliye there was an increase with 2.6 mg/l. Among monoterpenes, linalool, a-terpineol, citronellol, nerol and geraniol show significant differences between different terroirs.
