Volatile composition of Cabernet Sauvignon wines from Argentina, Portugal and Spain
Cabernet Sauvignon is one of the most cultivated grape varieties worldwide being grown in different environmental conditions due to its excellent adaptability. Volatile compounds deeply contribute to the sensory properties of wines therefore to wine quality
. The aim of this work was to compare the aroma profile of Cabernet Sauvignon wines from different geographical areas and climatic conditions, namely from Argentina, Portugal and Spain, from the vintage 2022. In addition, the volatile composition of the Cabernet Sauvignon Portuguese wines from three vintages was evaluated. The volatile composition was analyzed by LLE/GC-MS, allowing the quantification of 64 different compounds. The data was treated by PCA with XLSTAT-software, being the wines separated by countries. The first two principal components explained 100 % of the total variance. The variables which most influence the first component were acetates and esters (Isopentyl acetate, isoamyl acetate and diethyl malate) and volatile acids families, while the second was influenced by lactones and C6 families. The Argentine wines were separated by lactones and aldehydes and esters however the Spain wines by volatile phenols, volatile acid and the Portugal wine by less volatile acid. The Portuguese wines from the three vintages were separated based on their volatile composition. The first component was explained by aldehydes and volatile acids and the second component by volatile phenols and volatile alcohols.
