Effects of terroir on the terpene compounds of Muscat of Bornova Native white grape variety grown in Turkey

Abstract

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.

Volatile Compounds in Monovarietal Wines of Two Amarone Della Valpolicella Terroirs: Chemical and Sensory Impact of Grape Variety and Origin, Yeast Strain and Spontaneous Fermentation

“…The most abundant terpenes were β-citronellol, linalool, and in the case of Corvina, βmyrcene. The fact that terpenes were distinctive of grape origin is in agreement with other reports indicating these compounds as good markers of terroir influence [4,[37][38][39][40][41]. Terpenes have also been indicated as possible varietal markers of Corvina and Corvinone wines compared with other red wines [7], so that their variations in response to grape origin appear of particular interest in the context of Valpolicella wines.…”

“…41 Interestingly, some monoterpenes, including βcitronellol, have previously been reported to be significantly different in Muscat of Bornova wines from different terroirs in Turkey. 42 The results from our study suggest that β-citronellol and homovanillyl alcohol are possible markers for site-typicity differences in Mt. Difficulty wines.…”

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

“…On the analysis, a J&W fused silica DB-wax capillary column (60 m, 0.25 OD, 0.25 µm film) was used. The details of the analysis and the conditions of the instrument are described in Celik et al (2015). The volatile compounds were identified by comparing their retention index and their mass spectra on the DB-Wax column with those of a commercial spectra database (Wiley 6, NBS 75k) and against the instrument's internal library created from previous laboratory studies.…”
