PROBLEM TO BE SOLVED: To provide a container-packed beverage for sale in a heated state that is excellent in temporal stability of quality and is imparted with natural sweetness (sucrose-like sweetness) and a full-bodied taste (thickness) and to provide a method for improving the taste of a container-packed beverage for sale in a heated state.SOLUTION: The container-packed beverage for sale in a heated state includes sucrose, oligosaccharide, sugar alcohol, sucralose and acesulfame potassium. The container-packed beverage itself for sale in a heated state has a degree of sweetness of 9 to 15 (both inclusive) in terms of sucrose. The sucrose contained in the container-packed beverage for sale in a heated state has a degree of sweetness of 0.1 to 2 (both inclusive) in terms of sucrose. When the total value of the degree of sweetness calculated in terms of sucrose with regard to each of the oligosaccharide and the sugar alcohol contained in the container-packed beverage for sale in a heated state is X and the total value of the degree of sweetness calculated in terms of sucrose with regard to each of the sucralose and the acesulfame potassium contained in the container-packed beverage for sale in a heated state is Y, the value of X/Y is 0.2 to 0.7 (both inclusive).SELECTED DRAWING: None
