Two key factors for the production of quality brandies are the original wine spirit and its aging process. They aresignificantly conditioned by specific variables related to the base wine and the distillation method employed to produce thewine spirit used to obtain a finally aged brandy. This final beverage is therefore strongly influenced by its production process.The chromatographic instrumental fingerprints (obtained by GC FID) of the major volatile fraction of a series of brandieshave been examined by applying a chemometric approach based on unsupervised (hierarchical cluster analysis and principalcomponent analysis) and supervised pattern recognition tools (partial least squares–discriminant analysis and support vectormachine). This approach was able to identify the fermentation conditions of the original wine, the distillation method usedto produce the wine spirit, and the aging process as the most influential factors on the volatile profile PB SPRINGER SN 1935-5149 YR 2023 FD 2023-03 LK http://hdl.handle.net/10498/28383 UL http://hdl.handle.net/10498/28383 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 09-nov-2026
