The ester aroma profiles of five Chinese cherry wines and the perceptual interaction among esters were investigated in this study. 24 esters were identified by Gas chromatography-olfactometry (GC–O) and Gas Chromatography-Mass Spectrometer (GC–MS). According to addition/omission analysis, seven volatile compounds among them were selected and studied using sensory profiling and multivariate statistic methods such as Principal Component Analysis (PCA). In sensory analysis, a significant reduction of olfactory threshold for total aromatic reconstitution was induced by the addition among each of them in Feller’s additive model, which demonstrated their synergistic effects. The σ/τ plot showed that most of them were followed by a partial addition behavior. Furthermore, PCA indicated that the addition among each of them had a significant effect on fruity, floral, sweet and fermentation aroma intensity. Specifically, ethyl decanoate and methyl salicylate at sub-threshold concentrations were also likely to contribute to overall aroma. The results of perceptual interaction were mainly influenced by chemical structure and molecular polarity.
