GC-MS Description of the primary aroma structure of two Kadarka wines considered indigenous in Hungary

Two high quality Kadarka wines of the Great Plains of Hungary and Szekszard terroirs were thoroughly analysed by GC-MS measurements subsequent to a two step sample preparation method elaborated at our Department. The goal of the work was to describe the varietal relative aroma-picture of the Kadaraka species considered indigenous in Hungary. The relative aromagram construction method creates the possibility of studying the scent features by chemical classes separately. The data prove that the primary aroma-spectra beside certain smaller similarity differ to a reasonable extent due to the habitats of origin. The Kadarka of the poorer sand soil of the Great Plains is more fragrant than that of the loess of Szekszard. The analytical results are supported by the organoleptic experience as well.
