Abstract

Muscat of Bornova is a white and aromatic native grape variety of Vitis vinifera which is largely predominant in the İzmir-Manisa province of the Aegan region. In this study, the effect of three different terroirs (Kemaliye, Halilbeyli, Menderes) located in İzmir-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, α-terpineol, citronellol, nerol and geraniol show significant differences between different terroirs.
