Establishment of the Wine Quality Evaluation Model

ABSTRACT

In accordance with data provided from Mathematics Modeling Competition for National University students in 2012, it can be found whether grapes are high-quality or not as well as the direct relationship between the grape and wine quality by means of SPSS and other statistical softwares, through multivariate statistical analysis and data analysis, and by verifying the credibility what comments made on wine quality by members of liquor, additionally, quality classification on grapes is made through factor analysis. The physical and chemical indicators detected from wine and grapes reflect their quality to a certain extent. Through analysis of relationship between physical and chemical indicators concerning grapes and wine, a mathematical model used for evaluating wine quality with the help of physical and chemical indicators concerning grapes and wine is established, providing references for accurately evaluating wine quality.
