摘要: 目的:通过比较杨凌地区爱格丽葡萄不同采收期葡萄酒与蒸馏酒的香气成分,以期探索该地区爱格丽葡萄酿造蒸馏酒的最适采收期。方法:分别对8月18日、8月28日和9月5日采收的爱格丽葡萄进行酿酒、蒸馏实验,测定相关理化指标和香气成分。结果:8月28日采收的葡萄还原糖质量浓度最高,为(193.56±0.36)g/L,且葡萄酒中各多酚含量均最高;9月5日的葡萄酒中香气成分总量最高,且种类较丰富;8月18日的葡萄蒸馏酒中香气成分总量最高,种类较丰富。结论:3?个采收期中,9月5日的葡萄酒香气质量更优;而8月18日的蒸馏酒香气质量更优。

Abstract: Purpose: This study aimed to compare the aroma components of Ecolly wines and distillations made from grapes grown in Yangling, Shaanxi and harvested at different dates for the purpose of determining the optimal harvest date for distilled wine. Methods: Ecolly grapes were harvested on August 18, August 28 and September 5, then fermented and distilled. The physicochemical properties and aroma components were determined. Results: The reducing sugar content was the highest in the grapes harvested on August 28, (193.56 ± 0.36) g/L, and the contents of all the identified phenols were the highest in the resulting wine. The total content of aroma components was the highest in the wine made from grapes harvested on September 5, which showed a high diversity. However, for distilled wine, the total content of aroma components was the highest when grapes were harvested on August 18, which were highly diverse. Conclusion: The optimal harvest date for better aroma quality of wine was September 5, while that for better aroma quality of distilled wine was August 18.
