Research On Quality Of Wine Grape And Wine In Chang Li Production Area, Hebei Provine

Based on the terrain features and training systems,To study the quality of grape berries and wine, this experiment were conducted with different vinifera varieties, such as Cabernet Sauvignon, Cabernet Franc, Merlot, Syrah, Analysising climatic data and soil data of Changli County in Bodega Langes and huaxia great wall in 2010.The main contents were: climatic data of Changli county analysis; soil texture and nutrient content analysis; changes of reducing sugar, total acid and sugar acid ratio during the riping control; Comparative study of the quality of Grape and wine,analysis of individual phenols and anthocyanins using HPLC-MS, detection of the varietes and content of aroma substantials and the main compositions using GC/MS. By the study of the quality of grape and wine in this region, to chose appropiate grape varieties and effective vineyard management, thereby provide theoretical foundation for the grape and course of wine industry development.The results of this main research as follows:1. Through monitoring the riping process of Cabernet Sauvignon, Cabernet Franc, Merlot, Syrah grapeberries , to determine their best harvest in Changli. The best harvest of merlot is on September 20; Cabernet Franc is on September 24; Syrah is on October 4; the best harvest of Cabernet Sauvignon in the flat terrain is in advance than the slope terrain , flat terrain is on October 12, slope terrain is on October 14; For Tilted double cirsoid arms level of Cabernet Sauvignon, the best harvest is on October 11; Tilt single cirsoid single-arm made frame of Cabernet Sauvignon and tilt double cirsoid arms made frame of Cabernet Sauvignon are on October 13th or so.2. These results strongly suggest that significantly differences exist among all the grape samplings, for basis physical properties of cultivars'ripening fruits with the different terrains and training syetems. Under flat land, there were much difference in total phenols, total tannin and total anthocyanidin content of Cabernet Sauvignon,Cabernet Franc, Merlot, and they are the highest for Cabernet Sauvignon. Under slope land, The content of tannin of Cabernet Sauvignon is significant higher than Syrah. With the different training systems, Tilted double cirsoid arms level of Cabernet Sauvignon is significant or very significant higher than other training syetems.3. The results strongly suggest that significantly differences exist among all the wine samplings, for basis physical properties of wine with the different terrains and training syetems. Total phenols and total anthocyanidin content of Syrah wine in flat land are the highest, better than Cabernet Franc and Merlot wine,but has no difference with Cabernet Sauvignon wine; The content of tannin in Cabernet Sauvignon wine is the highest, and is much higher than Merlot wine. Total phenols and total tannin of Syrah in slope land are much higher than Cabernet Sauvignon wine; Total phenols, total anthocyanidin with Tilt double cirsoid arms made frame for Cabernet Sauvignon wine are much higher than others, while the content of tannin with Tilt single cirsoid single-arm made frame is the highest, and has no difference with Tilt double cirsoid arms level.4. The anthocyanin content of grape and wine in different test sites mainly is Petunidin, Petunidin and Malvidin, a few Dephinidin and Cyanidin content existed in grape, no Cyanidin content exist in wine. Malvidin content is highest both in grape and wine, and has the highest ratio in total anthocyanin. The anthocyanin content of Syrah grape and wine in different terrains is higher in the same terrains, the anthocyanin content of Cabernet Sauvignon grape and wine in slope land is higher than in flat land, while the anthocyanin content of Syrah grape and wine in flat land is higher than in slope land; under the different training syetems treatments, the anthocyanin content of Cabernet Sauvignon grape and wine with cirsoid single-arm made frame is higher than tilt double cirsoid arms made frame and tilt double cirsoid arms level.5. The individual phenols of grape and wine in different environment filed mainly is Benzoic acids, flavanols and Flavonols, a few cinnamic acids and stilbenes free phenol exist in grape, no stilbenes exist in wine; Flavonols content is highest in grape and have the highest ratio in total anthocyanin, while flavanols content is highest in wine and have the highest ratio in total anthocyanin. The individual phenols content of Syrah grape in the same terrains is higher, and The individual phenols content of Cabernet Sauvignon wine is higher; the individual phenols content of Cabernet Sauvignon grape in flat land is higher than in slope land, the individual phenols content of Syrah grape in slope land is higher than in flat land, the individual phenols content of Cabernet Sauvignon and Syrah wine in flat land is higher than in slope land; under the different training systems, the anthocyanin content of Cabernet Sauvignon grape and wine with tilt double cirsoid arms made frame is higher than tilt double cirsoid arms level and cirsoid single arm made frame.6.Detecting around 31 species of volatile compound in ripening grape berries, esters and Aldehydes account for about 75-90%, is the main aroma compound, Detecting around 43 species of volatile compound in wine, esters and aldehydes account for about 99% aroma comound, is the major aroma compound in wine; the aroma compound of Cabernet Sauvignon grape is the highest in the same terrains, the aroma compound of Syrah wine is higher in the same terrains; the aroma compound content of Cabernet Sauvignon and Syrah grape in slope land is always higher than in flat land in the different terrains, the aroma compound content of Cabernet Sauvignon and Syrah grape in flat land is always higher than in slope land in the different terrains; under the different training systems, the aroma compound content of Cabernet Sauvignon grape with tilt double cirsoid arms level is higher than tilt double cirsoid arms made frame and cirsoid single-arm made frame, the aroma compound content of Cabernet Sauvignon wine with cirsoid single-arm made frame is higher than tilt double cirsoid arms made frame l and tilt double cirsoid arms level.
