A. DOBOŠ, M. ORSZÁGOVÁ, J. MARCINA

The article deals with the results of analyses covering 9 sorts of brandy and cognac of Czechoslovak and foreign production. By using gas chromatography methods it was possible to study a number of properties, i.e. not only the density, percentage of alcohol, extract and volatile acids, but also the contents of ethyl acetate, methanol and fusel oils as: n-propanol, i-butanol, optically active amyl alcohol and i-amyl alcohol. It has been found that the majority of Czechoslovak distilleries making brandy apparently use, beside wine spirit, also other sorts of spirit. From the analysed marks of brandy " Carpathian Brandy" has the composition similar to typical  French cognac.
