天山北麓产区4个葡萄品种酿酒品质探究

Study on winemaking characteristics of four grape varieties in northern foothills of Tianshan mountains

为探究天山北麓产区‘马瑟兰’‘紫大夫’‘丹魄’和‘蒙特布查诺’4个葡萄品种的酿酒品质,2018年在新疆中信国安葡萄酒业公司进行发酵试验,对各发酵阶段的葡萄酒基本理化指标以及成品酒中酚类物质进行检测,并进行感官品尝。结果显示,‘紫大夫’酚类物质最丰富,所酿造葡萄酒感官品评得分较高;‘马瑟兰’中非花色苷酚类物质含量最高,果香浓郁优雅;‘蒙特布查诺’酚类物质丰富,但颜色较浅;‘丹魄’的酚类物质含量最低,且香气较弱。研究结果表明,‘紫大夫’‘马瑟兰’在该产区均具有良好表现,较适宜于优质干红葡萄酒的酿造;而‘蒙特布查诺’与‘丹魄’是否适宜于该产区干红葡萄酒的酿造仍有待进一步深入探究。

In order to explore winemaking characteristics of grape varieties of’Marselan’’Dornfelder’’Tempranillo’and’Montepulciano’in the northern foothills of Tianshan mountains,work was conducted in Xinjiang Citic Guoan Wine Co.Ltd.in 2018.Physical and chemical indicators of grape must,wine of the end of the alcoholic fermentation and the end of the malolactic fermentation were tested.Profiles of finished wine phenolics were tested,and wine sensory evaluation was also carried out.Analysis results showed that’Dornfelder’wines had the most abundant phenolics and it won the highest scores in sensory evaluation;’Marselan’wines had the highest content of non-anthocyanin phenolics,and their aroma was elegant with fruity style;’Montepulciano’wines had richer phenolic components,but their brightness value was also higher;’Tempranillo’had the lowest phenolic contents,as well as weak aroma.Therefore,’Dornfelder’and’Marselan’wines had good performance in this region,which were suitable for production of high quality dry red wine;whether’Montepulciano’and’Tempranillo’were suitable for dry red wine production in this region still need further exploration.
