摘要

The aromatic profiles of the 7 recommended cultivars for Vinho Verde wine productionhave been established with respect to monoterpenic and C13-norisoprenoids compounds,present either in free or in glycosidically bound fractions. Eighteen monoterpeniccompounds have been identified and quantified in the free form and 22 in theglycosidically bound form. Fifteen C13-norisoprenoids compounds have been identifiedand quantified in the glycosidically bound form. Loureiro variety can be easilydifferentiating from the 6 other varieties by important levels of linalool in the freefraction, above the odour perception threshold; in contrast, Alvarinho, Avesso, Arinto,Azal and Trajadura, geraniol prevails. Batoca variety showed a very poor monoterpenicprofile in the free form. In the glycosidically bound form Alvarinho is the richest in totalconcentration of monoterpenic compounds, followed by Loureiro.
