A filling apparatus for carbonated beverages including a filling valve connected to a beverage source under pressure and including a measuring cylinder movable into and out of a container to be filled. The measuring cylinder has a foot valve on its lower end and is telescopically associated with an inlet valve. The measuring cylinder is filled with a predetermined amount of beverage at superatmospheric pressure by moving the cylinder down into an empty container when the foot valve is closed and the inlet valve is open. The inlet valve is then closed and the cylinder is again moved down a slight amount to increase the volume thus reducing the pressure of a measured volume of beverage to atmospheric pressure. The foot valve is then opened and the measuring cylinder is moved upwardly at one rate and the container is moved upwardly at a slower rate relative to the closed inlet valve to transfer the measured quantity of beverage into the container at atmospheric pressure.
