To improve the quality of the wine obtained from the indigenous cultivar Feteasca regalã, six selected yeast strains were used for wine making at a pilot scale. Their quality was established after routine chemical analysis, organoleptic control and gas chromatographic studies concerning volatile compounds. 52 compounds were identified using gas chromatography/mass spectrometry. Two strains from yeast species S. cerevisiae var. ellipsoideus and S. carlsbergensis were more valuable than commercial yeast usually used in this region.
Key words: Wine / volatiles / gas chromatography/mass spectrometry / yeast / Feteasca regalã cultivar.
