To investigate the effects of origin and storage time on wine quality, HPLC and HS-SPME-GC–MS were employed to analyze the chemical compositions and VOCs of Cabernet Sauvignon wines from four sub-regions in Xinjiang and with five storage times. Results showed that most of the organic acids were reduced and the anti-oxidant activity decreased during storage. Wines from different regions exhibited differences in the contents of gallic acid, (+)-catechin and (−)-epicatechin. A total of 68 VOCs were identified, with esters and alcohols being the most dominant VOCs. In total, nine VOCs with OAV > 1 were detected in all samples, impacting wine flavor. Cabernet Sauvignon wines were differentiated using PCA and OPLS-DA. 15 and 17 chemical markers were screened based on VIP > 1 for wine of different sub-regions and bottle storage times, respectively. This research provides a data reference for quality characterization of wines obtained from different sub-regions and bottle storage times in Xinjiang.
