Methods and devices for enhancing drinking chilled drinking vessels are provided. In some aspects, a concentric set of arms or tabs in a pre-configured section of a drinking vessel applies holding pressure to expanded water poured within the section. A beverage is then poured over the frozen water, submerging it. In other aspects, holding pressure is maintained through flexible and/or adjustable arms, and lateral play eliminated, even if the frozen water melts. In other embodiments, a loop or set of loops extends from the center of the vessel above the section, and separate, flexible members (preferably cambered) are threaded through the loops after the water is frozen to apply greater holding pressure.
