The experiment were carried out in 7-year-old ‘Campbell Early’ grape to increase work efficiency by fruit cluster thinning methods (Pedicel and berry thinning). Pedicel thinning, such as labor-saving cluster thinning of grape, was 6.7 fold higher than the berry thinning for work efficiency. The fruit cluster weight and number of berry were lower in the fruit cluster thinning fruits than in the none-fruit cluster thinning, however, the soluble solid content (SSC) was high and titratable acidity (TA) was low in the fruit cluster thinning fruits than in the none-fruit cluster thinning fruits. Therefore, the bruising rate of berries was decreased in the fruit cluster thinning fruits. Quality uniformity by fruit cluster thinning was proper in fruit cluster weight of 350~450 g when SSC and TA in part of lower, middle and upper of cluster was considered.
