Study On The Sensory Characteristics Of Dry Red Wine Of Cabernet Sauvignon In Changli

Aroma is one of the most important sensory characteristics of wine, and it has regional character that makes it regarded as a basis of original wine protection. Wine aroma character can be used to differentiate various wines, which consists of the index and the basis of original wine protection. Through studying the aroma sensory properties of dry red wine of cabernet sauvignon in Changli, North China, some characteristic descriptors of aroma sensory attributes can be selected, and then the aroma sensory characteristics can also be obtained. This will lay the foundation for the establishment of the aroma fingerprint of dry red wine of cabernet sauvignon in Changli, and thus provide the theoretical basis for the geographical origin protection of Changli's red wine.In the paper, to determine the aroma sensory characteristics of Changli's red wine of Cabernet sauvignon, the sensory analysis panel was established first by selecting good tasters, and then the wines were evaluated by them. The main results obtained were as follows:1. Through the sensory training, examination and selection, 33 outstanding tasters were selected to organize the aroma sensory analysis panel, and the olfactory training significantly developed the perceptual abilities of the subjects.2. Through descriptive analysis by the tasting panel and multivariate statistical analysis, eight aroma descriptors identified were: blackcurrant, redcurrant, bilberry, green pepper, cut hay, vanilla, cinnamon and smoked.3. Based on the eight descriptors, the aroma sensory characteristics of Changli's red wine of cabernet sauvignon was achieved.Through the study on the sensory characteristics of dry red wine of cabernet sauvignon in Changli, eight descriptors of aroma sensory characteristics were selected, and then the aroma sensory characteristics were obtained. These results are important for further study on the establishment of the aroma fingerprint of dry red wine of cabernet sauvignon in Changli, and on the geographical origin protection of red wine in Changli.
