Abstract: A method and system of transferring matter through a sealed container during a bottling process are provided. The method includes accessing a headspace of the filled and sealed container by creating at least one opening. An inert gas is provided within the headspace while allowing O2 to exit from the headspace until substantially all of the O2 has been flushed out of the headspace. The headspace is then pressurized by continuing to direct the inert gas into the headspace after it has been flushed of O2. The at least one opening of the container is then sealed while the headspace is under pressure. The filled and sealed container can be a hot-filled container.
