A significant difference in table grape quality was found between harvest seasons, producers and cultivars. In general, 'Kyoho' grapes showed much greater difference in fruit quality than 'Campbell Early'. The ratio of 'Campbell Early' grapes with poor quality (below quality standard within grades), was higher in fruit harvested early in the season, mainly because of immature fruit harvest. In 'Kyoho', poor quality of fruit seemed to be derived from the deviation of cultural practice between producers. Major factors responsible for poor quality in both cultivars includes harvest of unripe cluster, poor sorting and grading, berry abscission, and poor coloration. It is recommended to introduce a new quality standards considering the market condition in 'Kyoho' or a fresh-cut technology of grape berries for niche market.
