The study of the wine quality of Merlot variety standard and clones 022, 025 and
029, obtained in the third phase of clonal selection of Merlot variety was done in the
period 2009-2012. The following components were measured: pH value of wines, total
acidity, aldehydes, esters, total polyphenols and ashes. The largest content of esters and
aldehydes was found in the wine of clone 025 and was significantly different compared
to the wines of standard and other clones. The content of polyphenols, total acidity and
pH values between the wines of standard and clones were not significantly different.
Ash content in the tested wines ranged from 2.623 g/l to 2.748 g/l, indicating their
authenticity. The studied wines are of good quality. U periodu 2009.-2012. godine izvršeno je ispitivanje kvaliteta vina
standarda sorte Merlot i klonova 022, 025 i 029, dobijenih klonskom selekcijom trećeg
vegetativnog potomstva sorte Merlot. Određeni su pH vrednost vina, ukupne kiseline,
aldehidi, estri, ukupni polifenoli i pepeo. Sadržaj estara i aldehida je najveći u vinu
klona 025 i statistički se značajno razlikuje u poređenju sa vinom standarda i ostalih
klonova. Sadržaj polifenola, ukupnih kiselina i pH vrednosti između vina standarda i
klonova se statistički značajno ne razlikuju. Sadržaj pepela u ispitivanim vinima je od
2.623 g/l do 2.748 g/l, što ukazuje na njihovu autentičnost. Ispitivana vina su dobrog
kvaliteta.
