Abstract

In order to obtain an evaluation system of wine, we use K-S test, t test, factor analysis and partial least squares regression analysis in the article, to grade the wine grapes. Then, we discuss the relationship among the wine grapes, the physical and chemical indicators and the qualities of the wine to finish the evaluation of the wine. First, we calculate the final scores given by the taster of each red and white wine sample. Then, we use K-S test to find that the two groups of data both obey the normal distribution. After using t-test based on paired data, we find that the two taster groups’ scores are both under the significance level of 0.05, which means there exists significant differences. For the next step, we use SPSS to do reliability analysis. We get the reliability coefficient of the two group, 0.921 and 0.861 respectively, variance are 13.506 and 12.589. Finally, after our comprehensive consideration, we think that the first group’s score for the red wine sample is more reliable, and the second group’s score for the white wine sample is more reliable.
