2. Wine quality is generally determined by employing a number of qualified wine tasting. Each wine in the wine tasting on classification index score, and then obtained the total score, to determine the quality of the wine. There is a direct relationship between quality of wine grape and wine. Physicochemical indexes of wine and wine grape can reflect the quality of wine and grapes in some degree. Annex 1 gives evaluation results for one year wine, composition data of the wine and grape wine at the year were given in annex 2 and 3. Please discuss the following issues: a. Are there significant difference between evaluation results of wine tasting in Annex 1 ? Which result is more credible? b. Class for wine grape according to the physicochemical indexes of wine grape, and the quality of wine. 2. Wine quality is generally determined by employing a number of qualified wine tasting.
