ChillCore solves the problem of warm wine, champagne, water or any soft drink, simply pre charge in the freezer for minimum 4 hours and place inside a warm bottle, after 10 minutes the bottle will be sufficiently chilled, (leave longer if you require a colder bottle). The ChillCore has a unique air flow system that allows the ChillCore to remain inside the bottle when pouring the wine, this ensures consistent temperatures and ease of use. When finished the ChillCore has a built in stopper for keeping the wine fresh for a few days; if kept inside the bottle, please store upright. To re charge the ChillCore please place back into the freezer.
