Characterization of Freisa Wines from Piedmont (Italy) by Aroma and Element Profile

The main purpose of this study was to characterize Freisa red wines from Piedmont (northern Italy) according their volatile organic compounds (VOCs) and elemental composition. Moreover, the authors investigated whether it possible distinguish among five different DOCs produced in on basis these chemical parameters. VOCs profile very similar, most abundant species detected were isoamyl alcohol, phenylethyl ethyl octanoate, diethyl succinate. Conversely, composition allowed us partially one DOC with respect others. Multivariate statistical analysis applied revealed differences other regions Italy. In particular, featured higher concentrations Cr Ni metals, which are strongly correlated soil Piedmont. These two elements hence good candidates as markers for
