Shiraz wine volatome from two different Australian GIs i.e. Orange and Griffith was compared using comprehensive GCxGC-TOF MS. Shiraz wines were made from grapes harvested in triplicates at two harvest dates from six vineyards in two GIs. A total of 133 compounds showed a significant trend between wines from cooler Orange, and warmer Griffith. Compounds associated with wines from cooler climate were grape derived volatiles, such as monoterpenes, sesquiterpenes, green leaf volatiles and some norisoprenoids. Fermentation derived compounds, such as esters and S-containing compounds showed no specific trend related to grape origin. In addition, wines could be also clearly separated according to the harvest date, irresp. of the climate, with C6 compounds, higher alc. acetates, and other esters contributing outmost to the differentiation of samples, whereas terpenoids and norisoprenoids did not have an influence. This study demonstrated plasticity of wine volatome related to grape origin and also maturity level (harvest date), irresp. of climate.
