Abstract: Based on Question A of Mathematical Contest in Modeling for college students in 2012, the empha-sis in this paper is mainly on the establishment of evaluation system of wine based on data mining technology. The wine quality is determined by the score of the wine tasting. We analyze the credi-bility of the liquor score by one-way ANOVA. We classify the wine grape by extracting common factors of some physical and chemical indicators from the wine grape, and by clustering the factor score and wine score. The stepwise regression model is established through the correlation be-tween the physical and chemical indicators and the physical and chemical indicators of wine grapes. By the regression model between the aroma substances and the score of the wine, the key physical and chemical indicators of wine quality will be found. In the end, some shortcomings of current rating system of wine will be pointed out.
