Fenological Characteristics of the Wines of Merlot Variety (Vitis Vinifera L.) and Clones Selected in Serbia

Abstract

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.
