'Feteasca neagră’ is a versatile grape variety, with results highly dependent on the cultivation region and viticultural practices. In Murfatlar this variety is cultivated both organically and conventionally, thus providing a good opportunity to study the behaviour of the variety in the two cultivation systems. Furthermore, in both culture systems, in some experimental variants 30% of the grapes from each vine were removed after the cluster formation - a practice often employed with an aim to obtaining a better-quality crop. The grapes harvested in autumn at technological maturity were vinified in 4 variants, in accordance to the viticultural practices applied: organic and conventional cultivation, with or without cluster thinning. In this work the influences of these viticultural practices on the volatile profile of the obtained wines were evaluated by using a flash GC-electronic nose. Although some differences are present when 30% cluster thinning is applied, the main influence in the volatile profile of wines is still induced by the cultivation system, irrespective of the grape reduction practice. The variability among the volatile profiles of the 4 groups of wines is explained in proportion of 85.3% by the cultivation system and only 12.4% by the grape reduction practice. The wines made from conventionally grown grapes display a more complex volatile profile as compared to the wines obtained from organic grapes.
