Abstract: A cooling coaster device and method for supporting and keeping a cold beverage container cool are provided. The cooling coaster device can include a relatively short, cup-shaped body including a closed bottom and a cylindrical sidewall forming an opening at an end thereof. A sealing ring gasket is integrally formed with the cylindrical sidewall in a vicinity of the opening. The sealing ring gasket can form a narrowest portion of the cup-shaped body and can be capable of forming a water and gas-tight seal when a beverage container is inserted into the cup-shaped body. The cooling coaster device can include a support extending into an interior of the cup-shaped body and forms a stop surface arranged a set distance from the closed bottom. The cooling coaster can be formed as an integral, one-piece structure and can keep the cold beverage container cool while not concealing its labeling and preventing the formation of a condensation ring.
