The objective of the current research was to study the effect of different alcohol reduction technologies on the chemical aromatic composition of La Mancha Tempranillo rosé wines. Volatile compounds were analysed using Gas Chromatography coupled to Mass Spectrometry (GC-MS), with previous isolation by solid phase extraction (SPE). C6 compounds were the only group of varietal compounds that was modified when the total dealcoholizing process was used. According to their odor descriptor, the volatile compounds were grouped into six odorant series. The total intensity of each aromatic series was calculated by adding the OAVs of the compounds appointed to this series. All wines showed the same sequence, only modified the intensity of the principal aromatic series, mainly in total dealcoholized wines. These studied wines maintain the aromatic typicality independently from ethanol concentration, which highlights the viability of these techniques as an alternative to the traditional winemaking process, which will allow diversifying wine’s actual market. |
