Claim 6:
7. A method of using a filling machine to fill containers with liquid, said filling machine comprising filling positions, each of which comprises a filling element, wherein each of said filling elements comprises a seal that seals a container's mouth, a filling valve, a gas valve, a liquid channel that, when said filling valve is opened, is in fluid communication with said container's interior, and a gas channel that, when said gas valve is open, is in fluid communication with said container's interior, wherein said filling machine is configured to introduce an inert gas into said container's interior via said gas channel to create a preload pressure in said container such that said inert gas in said container dissolves in said liquid, wherein said filling machine is further configured to introduce a volume of liquid into said container's interior through said liquid channel at a filling pressure that exceeds said preload pressure, and wherein said inert gas is selected from the group consisting of nitrogen gas and carbon-dioxide gas, said method comprising causing a preload pressure in said container, wherein causing said preload pressure comprises opening said gas valve to permit a quantity of said inert gas to enter said container through said gas channel, wherein said quantity of said inert gas, when dissolved into said volume, causes said volume of said liquid to have a desired quantity of dissolved inert gas, wherein causing said preload pressure further comprises measuring pressure in said container, said method further comprising accommodating a closure in a protection space adjacent to said seal, introducing said liquid into said container, after having introduced said liquid, setting a pressure in said container to be above saturation pressure of dissolved inert gas in said liquid, closing said container with said closure, and releasing said container.
