It is intended to provide a container-packed beverage containing a green vegetable in which the original green color of the vegetable is maintained and also the original flavor of vegetable beverage is maintained even in a common distribution form. A container-packed beverage in which the green color of a green vegetable has been stabilized can be provided by adding an additive for supplying copper ions and/or zinc ions to a liquid containing a ground substance of a green vegetable which is crushed such that a 100-mesh passing fraction accounts for 80% by weight or more and adjusting the concentration of copper and/or zinc derived from the additive in the beverage to 0.1 to 100 ppm. According to the invention, a container-packed green vegetable beverage, in which the green color of a green vegetable is stably maintained after heat sterilization performed when the container-packed beverage is produced or even after distribution and storage of the product, and which has an excellent flavor, can be provided.
