Key Compounds Of Provence Rose Wine Flavor

摘要

The aromas of French Provence rose wines were subject to in-depth gas chromatography and sensory analyses at the Research and Experimentation Center on Rose Wine (Centre de Recherche et d'Experimentation sur le Vin Rose). The study has demonstrated the oifactive contribution of different volatile compounds of fermentative and varietal origins. Dearomatization and reconstitution of flavor has revealed the preponderant character of ethyl esters and higher alcohol acetates, which are simple to determine and are at the origin of the fruity and amylic notes of rose wines. Moreover, the search for specific varietal compounds-well known in other types of wines-has made it possible to identify some key compounds of rose wine flavor: two volatile thiols (3-mercaptohexanol and 3-mercaptohexyl acetate), two furanic compounds (furaneol and homofuraneol), and one C13 norisoprenoid (β-damascenone). These compounds have now been measured in most of the experiments conducted at the Center on Rose Wine and are used as qualitative indicators in evaluation protocols for the exploitation of vines or for rose winemaking techniques.
