The present invention comprises methods and devices for preserving the carbonation or effervescence of effervescent beverages. In general, the methods comprise providing a device comprising a metallic shaft portion and an arm portion to an open beverage container containing an effervescent beverage. The devices may be made of metals or alloys and may be solid, hollow or plated materials, and may include nonmetal features. While the device is in place and the container is open to atmospheric air, the effervescence of the liquid is maintained for longer periods of time than are the same liquids in the similar conditions without the device present.
