The aim of our study was to identify and quantitatively analyze alcohol volatile congeners in different types of spirits from the domestic producers in order to evaluate their quality according to the Official Regulation.
A total of 100 samples of three different types of grape brandies (lozova rakia, komova rakia and vinjak) and 30 samples of plum brandies obtained from seven domestic producers were analyzed on the content of ethanol, ethyl acetate, methanol, i-propanol, n- propanol, i-butanol, n-butanol, i-amyl alcohol and n-amyl alcohol.
Maximum admissible limits were exceeded for methanol content in twelve of tested samples (2 samples of grape brandy lozova, 3 samples of grape brandy komova, 3 samples of grape brandy vinjak and 4 samples of plum brandies).
The major higher alcohol present in all tested samples was i-amyl alcohol. The content of i-amyl alcohol in grape brandy lozova rakia and grape brandy komova rakia didn’t show significant statistical difference, since the row material used was similar between the varieties.
Keywords: higher alcohol, lozova rakia, komova rakia, vinjak
