Aroma components of cv. Muscat of Bornova wines and influence of skin contact treatment

Aroma components of white wine made from cv. Muscat of Bornova, a natives grape variety of Vitis vinifera grown in Turkey, and the effect of skin contact treatment (15 °C, 6 and 12 h) on the aromatic profile of this wine were investigated. Aroma components were extracted with dichloromethane and then analysed by gas chromatography(GC)–flame ionisation detection and GC–mass spectrometry. A total of 72 components were identified and quantified. Skin contact treatment increased the amount of total aroma components. Wine produced with 6 h skin contact was the most preferred. From the 72 compounds identified, β-damascenone, ethyl hexanoate, ethyl butanoate, isoamyl acetate, 2-phenyl ethyl acetate, linalool, geraniol, and 2-phenyl ethanol were impact odourants of Muscat of Bornova wine on the basis of odour activity values (OAVs).
