PROBLEM TO BE SOLVED: To provide a method for producing a packed coffee drink, by which the coffee drink prevents precipitation in a high concentration, when stored, and can maintain the flavor of the coffee, especially the sour taste of the coffee. SOLUTION: This method for producing the packed coffee drink having a chlorogenic acid compound concentration of 0.14-0.5 mass% comprises (process 1) a process for subjecting a coffee extract solution originated from roasted coffee beans having an L value of 14-25 to an adsorbent treatment to obtain a coffee extract (a), (process 2) a process for mixing the coffee extract (a) with a coffee extract (b) originated from roasted coffee beans having an L value of 35-55 in a weight ratio of coffee solid content in (a):coffee solid content of (b) in a range of 8-15 to obtain a coffee solution, and (process 3) a process for subjecting the coffee solution to a thermal sterilization treatment, and further containing a process for adding a mannan-degrading enzyme between after the process 1 and before the process 3.
