A device that is placed around the neck of a beverage bottle. The device hangs from the neck of the bottle towards the body of the bottle and thereby cools the contents that are held within the bottle. The device is comprised of three sections, a top section that is elastic in nature and that defines an aperture that surrounds the circumference of a bottle. A middle section that extends from the top section for a distance of at least 1 inch, the middle section may or may not be elastic. And lastly, a bottom section that is composed of two ball sacs that are connected at a mid-juncture so that they are flexible enough to hang from the neck of the bottle while draping over the outside of the bottle so that the contents within the bottle are chilled. The bottom section may be made of materials that absorb moisture and that have insulating qualities.
