    Abstract:

    In order to investigate the influence on impregnation technology for wine aroma and flavor,Cabernet Sauvignon grape was used to produce dry red wine by 7 kinds of impregnation technology(traditional impregnation,CO2 impregnation,cold impregnation,30 ℃,40 ℃,50 ℃,60 ℃ hot impregnation technology ). Characteristics were determined and aroma substances were analyzed by gas chromatography-mass spectrometry(GC-MS) to evaluate their contribution to the flavor. The results showed that,the impregnation temperature was proportional to the content of total phenol and total anthocyanin,and inversely proportional to the total acid content. Aroma analysis showed that there were many kinds of aroma compounds in the cold impregnation technology wine,and the sensory properties were better. The content of esters was higher but alcohols and acids was lower after CO2 impregnation technology. 40 ℃ hot impregnation technology can change wine aroma structure,accelerate wine ripening,other hot impregnation technology for wine aroma positive influence was less. In conclusion,cold impregnation process is more suitable for brewing Cabernet Sauvignon dry red wine.
