A total of 49 phenolic compounds were identified from the aged red wines made from Cabernet Gernischt (Vitis vinifera L. cv.) grapes, a Chinese characteristic variety, including 13 anthocyanins, 4 pryanocyanins, 4 flavan-3-ol monomers, 6 flavan-3-ol polymers, 7 flavonols, 6 hydroxybenzoic acids, 5 hydroxycinnamic acids, 3 stilbenes, and 1 polymeric pigment. Evolution of these compounds was investigated in wines aged 1 to 13 months. Variance analysis showed that the levels of most phenolics existed significant difference in between wines aged 3 and 9 months. Cluster analysis indicated that 2 groups could be distinguished, one corresponding to wines aged 1 to 3 months and the other to wines aged 4 to 13 months. It was thus suggested that there were 2 key-stages for the development of fine wine quality, at the aged 3 and 9 months, respectively. This work would provide some helpful information for quality control in wine production.
