Abstract. The results of the four-year investigation of the grape
cultivars impact of the first Yugoslav interspecies hybrids Lucija and
Mediana on the grape brandies quality are presented. The experiment was
carried out with reference to the standard grape cultivar Smederevka intended
for production of grape brandies. Investigation covered a procedure for
establishing parameters, which determine the quality of strong alcoholic
beverages and organoleptic rating. Higher presence of methanol with reference
to standard cultivar was not established in the investigated hybrids brandies,
which demonstrates properties similar to that of precious cultivars. The
highest average content of higher alcohols was found out with the Mediana
grape brandy, which amounts to 3295.3 mg/Laa, followed by the Smedervaka
grape brandy with 3261.8 mg/Laa, the Mediana/Lucija grape brandy with 3130.0
mg/Laa and the Lucija grape brandy with 2940.0 mglLaa of higher alcohols.
The concentration of higher alcohols positively affects aroma of the beverage.
The Mediana grape brandy and the variant where fermentation of the Mediana
and Lucija grapes in the 50:50 ratio was carried out possess better organoleptic
characteristics than those of Smederevka, while the Lucija grape brandy
shows worse organoleptic characteristics.

ISPITIVANJE UTICAJA SORTE GROŽĐA NA KVALITET
RAKIJA LOZOVAČA
U ovom radu su prikazani četvorogodišnji rezultati istraživanja uticaja
sorte grožđa, prvih jugoslovenskih interspecijes hibrida Lucije i Mediane,
na kvalitet rakije lozovače. Ogled je izveden u odnosu na standardnu sortu
grožđa za proizvodnju rakija lozovača Smederevku. Ispitivanje je obuhvatilo
utvrđivanje parametara koji određuju kvalitet jakih alkoholnih pića i organoleptičko
ocenjivanje. Rakije lozovače ispitivanih hibrida nemaju veći sadržaj metanola
u odnosu na standardnu sortu Smederevku, što potvrđuje bliskost osobina
ispitivanih hibrida sa plemenitim sortama. Najviši prosečan sadržaj viših
alkohola utvrđen je u lozovači Mediane i iznosi 3295,3mglLaa, a zatim slede
lozovača Smederevke 3261,8mg/Laa, lozovača Mediana/Lucija 3130,0mg/Laa
i lozovača Lucija koja je imala 2940,0mgLlaa viših alkohola. Navedeni sadržaj
viših alkohola ima pozitivan uticaj na aromu pića. Lozovača sorte Mediana
i varijanta gde je izvršena fermentacija sorti grožđa Mediana i Lucija
u odnosu 50%:50% poseduju bolje organoleptičke osobine od standarda Smederevke,
dok lozovača sorte grožđa Lucija ima lošije organoleptičke osobine.
