Abstract:

In order to investigate the effects of different winemaking processes on volatile compounds of wine made from
hermaphrodite grape variety NW196, the volatile components in wines were extracted by liquid-liquid method and analyzed
by gas chromatography-mass spectrometry (GC-MS). Results indicated that carbonic maceration increased the contents of
esters, acids and phenols as well as the species and contents of volatile compounds in wines while malolactic fermentation
enhanced the contents of alcohols, acids, ketones and phenols as well as the contents of volatile compounds in wines. The
combination of carbonic maceration and malolactic fermentation could form more volatile compounds in wines and a unique
taste which was different from traditional wine.

Key words: winemaking process, hermaphrodite grape variety NW196, carbonic maceration, wine, volatile
