Abstract

The differences in volatile components of grapes among 11 wine grape cultivars, grown in Japan were investigated.
Grape musts were distilled with reduced pressure, extracted by dichloromethane, concentrated under vacuo and analyzed by gas chromatography.
Comparatively larger amounts of volatiles were found in ‘Riesling’and ‘Chardonnay’ among white wine cultivars and predominantly in ‘Cabernet Sauvignon’ among red wine cultivars. The above cultivars contained abundantly volatile esters, alcohols and C6-compounds compared with other European and Japanese native cultivars.
The volatiles found abundantly in all of cultivars were iso-butanol, iso-pentanol, 2-phenylethanol and C6-compounds, although methyl anthranilate was not detected in all of the cultivars examined.
