本研究以单品种‘赤霞珠’葡萄酒为主体，‘品丽珠’、‘马瑟兰’和‘小味儿多’葡萄酒分别为配体以10%、20%、30%三种比例进行发酵后二元混酿，旨在通过不同风格葡萄酒间不同比例的混和，弥补单一品种葡萄酒的缺陷和提升风味品质。通过气相色谱-质谱联用（GC-MS）和高效液相色谱-三重串联四极杆质谱（HPLC-QqQ-MS/MS）测定葡萄酒中风味物质，结合感官定量描述（QDA）和CIELAB检测体系对香气和颜色感官品质进行分析。瓶储6个月后，仅果香酯类物质质量浓度较高的‘品丽珠’在混酿比例大于20%时显著提高了混酿组乙酸酯类物质质量浓度（p<0.05）；‘马瑟兰’的比例大于10%时能显著提高类异戊二烯类物质质量浓度，有利于提高花香降低生青味，同时降低黄色色调；‘小味儿多’的混酿比例在30%时有较好效果，显著提高混酿组黄烷醇（1.43倍）、黄酮醇（1.27倍）、酚酸（4.68倍）质量浓度有利于颜色稳定。因此可通过发酵后混酿调控‘赤霞珠’葡萄酒香气和颜色品质，为科学制定混酿方案提供理论依据。

To avoid deficiencies in monovarietal wines and improve flavor quality by blending different wines with different proportion through the technique of wine blending after fermentation (‘coupage’), Cabernet Sauvignon wine was regarded as base wine and blended with Cabernet Franc, Marselan, and Petit Verdot wines with proportion of 10%, 20%, 30%, respectively. Gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography triple quadrupole mass spectrometry (HPLC-QqQ-MS/MS) were used to detect flavor compounds, namely, volatile aroma compounds and phenolic compounds. Quantitative descriptive analysis (QDA) and CIELAB model were conducted to evaluate the difference of wine sensory quality. The results showed it was not an efficient way to increase fruity aroma by merely blending wines with high level of esters. Only Cabernet Franc wine with proportion above 20% increased the concentration of acetates in blending wine samples after 6-month bottle aging (p<0.05). Marselan wine with proportion over 10% could promote flower attribute and reduce herbal notes by increasing concentration isoprenoids, and lower the yellow hue at the same time. Petit Verdot wine with proportion of 30% had great contribution to the improvement of phenolic composition, especially by increasing the concentration of flavanols (1.43 times), flavonols (1.27 times) and phenolic acids (4.68 times), which was beneficial for color stabilization. Therefore, it is practicable to regulate aroma and color characteristics in ‘Cabernet Sauvignon’ wines through wine blending after fermentation, which provides theoretical basis for scientific design of ‘coupage’.
