Abstract
Aroma compounds are vital to wine quality, determining their odour and varietal characteristics. Their concentration in wine depends on grape variety, light intensity, soil, maceration, fermentation temperature, etc. This study is focused on the determination of volatile compounds in Vranec wines, applying headspace solid phase microextraction (HS-SPME) method for sample preparation, coupled to GC-MS technique [1]. Vranec wines were produced with different vinification techniques, applying maceration time of 4, 7, 14 and 30 days, in the presence of enzyme and oak chips during fermentation, in order to determine the influence of vinification conditions on the aro...
