Now you can enjoy your favorite wine at perfect cellar temperature, instantly, as you pour! A must for every wine enthusiast, this patent pending system is getting rave reviews by experts everywhere. The RAVI Wine Cooler is based on the innovative concept of cooling wine at the very moment it’s served. It’s not the bottle that is cooled, but the wine itself. With an internal tube made from the same stainless steel used for fermentation tanks, RAVI maintains the wine’s characteristics and never alters the taste. The RAVI is kept in the freezer. Once you remove it from the freezer, place the RAVI on the neck of your wine bottle.
