Wine goes from room temp to serving temp in seconds! Remove your Ravi from the freezer, insert it in your bottle, and pour. Wine passes through the frozen steel chamber inside into your glass, chilling your red or white to perfection (similar to the way the frozen tub of an ice cream maker turns cream into a cool dessert). Finger tip-control air inlet helps you adjust serving temp and prevent dripping. Give your vodka a quick chill, too—pour it through Ravi and enjoy! Instructions included.
