为了使白酒等级的鉴别与评定更为客观化、数据化，从3类不同感官等级1年陈白酒基酒GC图谱中筛选了15个特征指纹峰用于构建指纹图谱。采用系统聚类分析对不同感官等级白酒基酒指纹图谱进行鉴别。所得结果与实际感官评定结果大致相同。说明系统聚类分析可以用来鉴别不同感官等级白酒基酒。
為瞭使白酒等級的鑒彆與評定更為客觀化、數據化，從3類不同感官等級1年陳白酒基酒GC圖譜中篩選瞭15箇特徵指紋峰用于構建指紋圖譜。採用繫統聚類分析對不同感官等級白酒基酒指紋圖譜進行鑒彆。所得結果與實際感官評定結果大緻相同。說明繫統聚類分析可以用來鑒彆不同感官等級白酒基酒。

To make the identification and the evaluation of Luzhou-flavor liquor more objective and figurative, the fingerprints of base liquor （1 year liquor age） of three different sensory grades were obtained and 15 representative fingerprint peaks from GC profiles were screened out to establish fingerprint data. The discrimination of the fingerprint was performed by hierarchical cluster analysis.The results showed that the discrimination of base liquor of different sensory grape by such fingerprint was generally the same as sensory evaluation. Therefore, such method could be used to discriminate base liquor of different grade.
