There has been a need to provide a green tea beverage packed in a container which exhibits a smooth feeling in the throat and a lingering taste when the beverage is drunk cold, in particular even when time has passed since the container was opened and the beverage temperature has increased and become lukewarm. The present invention provides a green tea beverage packed in a container which exhibits a smooth feeling in the throat and a lingering taste when the beverage is drunk cold, in particular even when time has passed since the container was opened and the beverage temperature has increased and become lukewarm, by adjusting a particle diameter of cumulative 90 mass % (D90) in a tea extracted liquid to 3 μm to 60 μm and adjusting a sugar/tartness degree ratio to 0.12 to 0.43.
