Abstract: A beverage cooler that warms very slowly over time is provided which has a low profile and a configuration that allows one beverage cooler to be nestably stacked atop another beverage cooler. The beverage cooler includes a base which defines an inner fluid-receiving reservoir and a fluid-fill aperture through the base which allows access to the inner fluid-receiving reservoir. A central recess in an upper surface of the base is configured to either receive a lower portion of a pint glass or so that the beverage cooler may serve as a pet water dish. In this latter embodiment, a selectively sealable aperture is provided through the upper surface of the base and within the central recess.
