The Chillaerator eliminates the need for an ice bucket by chilling the wine from inside the bottle. It will keep white wine chilled for up to an hour or bring down red wine to room temperature. It's great for both red and white wine, as it also aerates the bottle. These are very simple to use: 1) Put the stainless-steel rod in the freezer about 2 hours before using (or can be left in freezer) 2) Screw onto acrylic aerator/ pourer 3) Put tightly on wine bottle 4) Pour directly out of the Chillaerator and enjoy!
