Volatile compounds in grapes and wines from two Muscat varieties cultivated in Greek islands

Abstract

The concentrations of free and glycosidically linked monoterpenes and volatile alcohols in grapes and wines from the cultivars Muscat lefko and Muscat of Alexandria, cultivated in the islands of Samos and Lemnos respectively, were determined. The relationship between free and linked monoterpenes in grapes and wines as well as the relationship between grapes and wines in their monoterpene content was investigated, showing some differences between the two cultivars and the different vineyards. It is also demonstrated that skin-contact for 8h at a temperature up to 15 °C, resulted in marked increases in the concentrations of free and linked monoterpenes in wines from both Muscat cultivars.
