Each varietal wine has its own characteristic aroma profile, which can be described by determination of its volatile organic compounds (VOC) profile. The aim of this work was to characterize Gewiirztraminer wine using two-dimensional gas chromatog. coupled to time-of-flight mass spectrometry, preceded by solid phase microextraction of volatile compounds from headspace, and identify voe responsible for typical aroma profile of this varietal wine. In 30 wine samples, in total 288 volatiles were identified, while 153 were found in each studied sample. These common attributes creating varietal fingerprint of Gewiirztraminer wine were represented by 50 esters, 28 terpenoids and Cl3-norisoprenoids, 25 higher alcs., 23 furans, pyrans and lactones, 13 volatile acids, 10 carbonyl compounds, 3 sulfur compounds and 1 volatile phenol. Differentiation among Gewiirztraminer wines and wines of other vine varieties was mainly perceived through the following components: els-rose oxide, sulcatol, (Z)-β-ocimene, 4-vinyl-guaiacol, furan, 2$-furandicarboxaldehyde, 2(5H)-furanone, solerone, ct-angelica lactone, 2-hydroxy-y-butyrolactone, B-hydroxybutyrolactone, Me pyruvate and Me formate. Regardless of vintage and used technol., in all tested Gewiirztraminer samples, voe previously connected only with oak (maltol), botrytization (p-cymene), non-saccharomyces activity (blackberry thiophenone), insect pheromones or plants other than Vitis vinifera (isogeraniol, β-farnesene, sulcatone, sulcatol, Et 3-methylthiopropionate) were identified.
