Apparatus and method for limiting the loss of carbonation from a body of carbonated liquid such as champagne within a container. The apparatus includes a container that has an exit positioned above the liquid. A pouring portion defines a passageway from the interior of the container to the exit. The apparatus also includes a control device that includes an elongated control section and a support section for supporting the control section in the passageway. The control section and the passageway are sized, configured and proportioned relative to one another so that the control section can be within the passageway with a clearance space between it and the passageway wall along the full length of the control section. This allows at least some leeway or latitude in the lateral or transverse positioning of the control section in the passageway. This also allows a single control device to accommodate manufacturing variations in container passageway size, and some different specified size container passageways.
