This invention relates to an improved beverage container which permits one to effect a rapid carbonation of the liquid content with dry ice without excessive gas pressure build up. The new container comprises an outer housing shell having an opening at the top equipped with a lid, a water-level mark on the outside near the top and a fluid-flow release valve extending through an opening in the housing near the bottom, and a removable support plate resting near but above the bottom of the housing and extending over the internal terminal of the release valve, the support plate holding the solid dry ice which is added to the container.
