Lugana and Verdicchio are two Italian white wines with a Protected Designation of Origin (PDO) label. These two wine types are produced in different regions using the same grape variety. The aim of this work is to investigate the existence of volatile chem. markers that could help to elucidate differences between Lugana and Verdicchio wines both at chem. and sensory levels. Thirteen com. wine samples were analyzed by Gas Chromatog.-Mass Spectrometry (GC-MS), and 76 volatile compounds were identified and quantified. Verdicchio and Lugana had been differentiated on the basis of 19 free and glycosidically bound compounds belonging to the chem. classes of terpenes, benzenoids, higher alcs., C6 alcs. and norisoprenoids. Samples were assessed by means of a sorting task sensory anal., resulting in two clusters formed. These results suggested the existence of 2 product types with specific sensory spaces that can be related, to a good extend, to Verdicchio and Lugana wines. Cluster 1 was composed of six wines, 4 of which were Lugana, while Cluster 2 was formed of 7 wines, 5 of which were Verdicchio. The first cluster was described as “”fruity””, and “”fresh/minty””, while the second as “”fermentative”” and “”spicy””. An attempt was made to relate anal. and sensory data, the results showed that damascenone and the sum of 3 of esters the Et hexanoate, Et octanoate and isoamyl acetate, was characterizing Cluster 1. These results highlighted the primary importance of geog. origin to the volatile composition and perceived aroma of Lugana and Verdicchio wines.
