Wine chiller that chills the wine, not the bottle
The Ravi is a wine chiller that can chill wine as it is poured. The wine is chilled as it flows through the chilling tube that has been prepared by freezing in the freezer. As the chilled tube is warmed up by the room's hotter temperature the wine needs to pass slower through the tube to get the right temperature. This is achieved by an air valve that is controlled by the thumb.
