Abstract

Volatile compounds of young Cabernet Sauvignon wines from the flat and slope lands grown in Loess Plateau region (China) were firstly investigated in this research. Among the volatile compounds analyzed by HS-SPME with GC-MS, a total of 43 and 45 volatile compounds were identified and quantified in the flat and slope lands wines, respectively. In the volatiles detected, higher alcohols formed the most abundant group in the aromatic components of the 2 wines, followed by esters and fatty acids. According to their odor active values (OAVs) and relative odor contribution (ROC), the aromatic profiles for the 2 wines were similar, showing only quantitative but not qualitative differences. Ethyl octanoate, ethyl hexanoate and isoamyl acetate were found to jointly contribute to 98.8% and 99.2% of the global aroma of the flat and slope wines, respectively. These odorants are associated with “fruity’’ and ‘‘ripe fruit’’ odor descriptors.
