Headspace solid-phase microextraction gas chromatography/mass spectrometry in the analysis of the aroma constituents of 'Cannonau of Jerzu' wine.
"Cannonau of Jerzu" wine is a typical Sardinian product, obtained from only one particular grape variety. Its aroma profile is highly characteristic from the organoleptic point of view but, until now, no analytical investigation of the aroma components has been reported. This aspect has been studied by headspace solid-phase microextraction coupled with gas chromatography/mass spectrometry (GC/MS). Using this approach, 76 abundant aroma components were identified. The results thus obtained show on one hand that the terpene profile is, as expected, dependent on the quality of the grapes (in terms of selection before vintage), and, on the other, that some components are strongly dependent on the production and ageing method.
