Abstract: A device that attaches to a bottle's neck has a base that secures to the bottle's neck and has two passages that traverse the base. The first passage leads to an enclosure located above the base that holds cooling material and optionally has a conduit that improves the heat exchange between a dispensing liquid and the cooling material retained in the enclosure. The exit passage of the enclosure has in at least one embodiment a valve. The second passage through the base forms a vent line that is located entirely below the enclosure and allows air to flow into the bottle as bottle's contents are dispensed through the first passage.
