Grape was one of the fruits that carried out competition earlier in Taiwan. The evaluation and competition referred to the standards of high quality grape, the items were divided into appearance, cluster weight, berry weight, rate of berry-drop, berry coloration, sugar contents, acidity and flavor, in which the standards of berry weight may be adjusted for the summer crop and winter crop. The main defects in the competition samples were agrichemical blotches on the berry skin, imperfect berry coloration and bad cluster volume. These defects of agrichemical blotches had improved through bagging and the berry coloration had enhanced through controlling the yield amount, but the cluster volume still needs improvement. The overall suggestions on the improvement of the competition and evaluation in grape are as follows: strengthen of the promotion advertisement effects and the vineyard demonstration effects, carry out the activities in different crop seasons and production areas, expanding the scale of the evaluation and competition to increase the income profits of the excellent class grapes, and the combination of the evaluation standards with the market grading.
