Abstract: To solve the problems occurred in white wine induced by quality of full matural grape in Xinjiang, Chardonnay berry have been harvested at three periods as CH-1: 2008-09-02; CH-2: 2008-09-08; CH-3:2008-09-14 in Manasi county in 2008, and the qualities of dry white wine affected with harvesting time was studied. The results showed that: 1) main aroma compounds in Chardonnay wine are isoamyl alcohol, 2-phenylethanol, 2-methyl propanol and ethyl acetic. Ordering of the contents of the first ten volatile compounds of wines differed with maturity of grape, In CH-1, the first ten higher aroma compounds are 2-methyl propanol, isoamyl alcohol, ethyl acetic, 2-phenylethanol, 1-propanol, 1-butanol, isoamyl acetate, hexyl alcohol, ethyl caproate and benzyl alcohol, which occupied 99.64% of the total volatile compounds dctected. In CH-2, they are isoamyl alcobol, 2-methyl propanol, ethyl acetic, 2-phenylethanol, 1-propanol, hexyl alcohol, 1-butanol, isoamyl acetate, benzyl alcohol and ethyl caproate, which occupied 98.77% of the total volatile compounds detected. In CH-3, they isoamyl alcohol, 2-phenylethanol, 2-methyl propanol, ethyl acetic, 1-butanol, ethyl decanoate, ethyl octanoic, 1-nonanol, diethyl succinate and ethyl caproate, which occupied 97.28% of the total volatile compounds detected. 2) sensory evaluation indicated that the quality of wines ordered as CH-3>CH-2>CH-1, 3) index of optimum harvesting time pue 8/B io souad mortsoeoneens ooer9'9e ort eens uaoaamsKeopeo () tannins 0.388 mg/g

近年来,随着社会的发展和人们生活水平的提高,优质葡萄酒逐渐成为消费热点。葡萄酒的酒质主要取决于葡萄品种,其次是通过工艺使完全潜存于葡葡原料中的优良品质得以充分表现"。般来说,酿酒葡萄成熟的判定与酿酒葡萄的特点及酿造工艺要求有关。新疆玛纳斯县气候独特、葡葡品质优秀,但因地理与技术限制,对其品质的研究主要集中在气象因子与葡翻品质的相关性研究上叫,缺乏深入分析葡葡与葡葡酒的常规指标和内在指标。因该地气候干燥,葡萄果实水分蒸发散失易致使葡萄“糖高酸低”且成熟迅速,在葡萄酒酿造中需加酸或与其他葡萄汁混合发酵,使单品种酒生产规模受到约束,使酒体潜在品质表现不全面。因此,通过对该地区葡萄果实成熟度

的控制,按照不同成熟度酿制葡萄酒,研究葡萄酒的质量变化,为选择霞多丽的最佳采收期、提高葡萄酒质量莫定基础。
