Volatile composition of red wines made from cv. Kalecik Karast, a native grape variety of Vitis vinifera grown in Turkey, was investigated during two vintages. Volatile compounds were extracted with dichloromethane, and then analysed by gas chromatography-flame ionisation detection (GC/FID) and gas chromatography-mass spectrometry (GC/MS). Seventy-eight aroma compounds were identified. Isoamyl alcohol, ethyl hexanoate, ethyl octanoate, ethyl decanoate, isoamyl acetate, 2-phenyl ethanol and octanoic acid were potent aroma compounds on the basis of gas chromatography/olfactometry (GC/O) analysis and odour activity values (OAVS).
