A new anal. technique was developed for the study of the organoleptic compounds (flavor profile) of the Graciano Vitis vinifera wine variety. The cv. Graciano is a singular variety of red grapes with its origins in La Rioja and Navarra (northern Spain). This variety transfers an intense red color, aroma and high acidity to musts and provides greater longevity and, consequently, a better capacity for aging wine. A new dual-stir bar sorptive extraction approach coupled with thermal desorption (TD) and GC-MS has been used to extract the volatile and semivolatile compounds In this extraction step, the optimal values for the exptl. variables were obtained through the Response Surface Methodol. (RSM). Full scan chromatogram data were evaluated with two deconvolution software tools, and the results were compared. The volatile and semivolatile components were identified with an MS match ≥80%. As a result, the flavor metabolome of the Graciano Vitis vinifera wine variety was obtained, and 205 metabolites were identified using different databases. These metabolites were grouped into esters, acids, alcs., nitrogen compounds, furans, lactones, ketones, aldehydes, phenols, terpenes, norisoprenoids, sulfur compounds, acetals and pyrans. The majority of the metabolites observed had already been reported in the literature; however, this work also identified new, previously unreported metabolites in red wines, which may be characteristic of the Graciano variety.
