A cup for containing therein a carbonated beverage is provided, comprising a smooth interior surface having distinct upper and lower portions. The interior surface is provided with one or more nucleation sites defining a predetermined total nucleation area and comprising an uppermost nucleation zone disposed on the upper portion of the interior surface, and a lowermost nucleation zone disposed on the lower portion of the interior surface. The lowermost nucleation zone comprises at least a quarter of the total nucleation area, and the lower portion does not extend above the lowermost third of the height of the cup.

A closure for a container. The closure includes a carbon dioxide emitter, and a release rate control layer that is configured to control release of carbon dioxide from the carbon dioxide emitter into the container when the closure is coupled to the container.

The present application is directed to a method of introducing one or more gases into a liquid that includes introducing a feed liquid into at least one vessel, injecting one or more non-CO.sub.2 gases and, optionally, CO.sub.2 gas into the feed liquid in the at least one vessel to obtain an effervescent liquid, filling one or more containers with the effervescent liquid, and sealing the one or more containers to obtain a packaged beverage, wherein the packaged beverage has less than 4.0 standard volume of CO.sub.2 dissolved per volume of liquid, and wherein the packaged beverage has between 0.01 and 1 standard volume of one or more non-CO.sub.2 gases dissolved per volume of liquid. Also, associated systems, devices, and beverages are disclosed.
