贺兰山东麓红葡萄酒等级划分客观标准的初步研究

对贺兰山东麓各等级葡萄酒理化指标进行分析，根据葡萄酒的理化指标参数与等级之间的相关性，初步研究葡萄酒客观等级划分标准。选用在宁夏地区主栽品种赤霞珠和蛇龙珠红葡萄酒的30个样品，7个理化参数，利用相关性分析研究了理化指标与各等级葡萄酒的相关性；利用逐步判别分析方法找到对贺兰山东麓红葡萄酒分级影响最为重要的因子，并初步建立了等级识别模式。结果表明，葡萄酒的总酚、单宁和总酸等理化参数与葡萄酒等级划分有极显著相关，通过逐步判别分析得到总酚和总酸可以判别葡萄酒的等级。本研究对宁夏贺兰山东麓葡萄酒的等级划分客观标准具有一定的拳者价值。

Preliminary Study on Objective Rating Standards of Red Wine of Eastern Area of Helanshan Mountain

This paper analyzed the physical and chemical indexes of wines of all grades from eastern area of Helanshan Mountain, and according to the relationship between the parameters of physical and chemical indexes of wine and its grade, the external rating standards of wines were studied primarily. Totally 7 physical and chemical parameters and 30 samples of Cabernet Sauvignon and Cabernet Shelongzhu which were main grape varieties in Ningxia were analyzed. The relationship between physical and chemical indexes and wine＇s grade was stud- ied with relativity analysis. The most important factors affecting the grade of red wine from eastern area of Helanshan Mountain were found by methods of gradual distinguishing analysis, and the grade-distinguishing pattern was established primarily. The result showed that physical and chemical parameters such as total phenols tannin and total acidity were very significantly related with the rating of wines. By gradual distinguishing analysis, total phenols and total acidity could be used to rate wines. This work offered some reference values for objective rat- ing of wines from eastern area of Helanshan Mountain of Ningxia.
