PROBLEM TO BE SOLVED: To provide a packed beverage having pickled plum-like taste without use of pickled plum, and manufacturing method thereof.SOLUTION: The packed beverage includes plum fruit juice, with a ratio of the total amount of citric acid per unit volume to the total amount of sodium per unit volume, i.e. (the total amount of citric acid)/(the total amount of sodium), of 6.5 to 22, and with a ratio of essence components to acidity, i.e. (the extract value)/(the acidity), of 6 to 16.5. The manufacturing method of the packed beverage includes an addition step S1 of adding plum fruit juice to a mixing tank for mixing raw materials, and an adjustment step S2 of adjusting the amount of the plum fruit juice, the total amount of citric acid, and the total amount of sodium, achieving a ratio of the total amount of citric acid per unit volume to the total amount of sodium per unit volume, i.e. (the total amount of citric acid)/(the total amount of sodium), of 6.5 to 22, and a ratio of essence components to acidity, i.e. (the extract value)/(the acidity), of 6 to 16.5.
