Pour perfectly chilled wine–instantly.Bring out the best in your wine by serving it at just the right temperature without ice buckets or special refrigeration. Simply store the Ravi Instant Wine Refresher in your freezer for at least six hours, then attach it to your wine bottle. The wine chills to perfection when you pour it through the Ravi and use the air-intake valve to control the flow for regulating wine temperature. Ravi can cool a full bottle of room-temperature red wine to 64 degrees F, or chill many glasses of white wine to as low as 40 degrees F. The outside of the Ravi Instant Wine Refresher is an insulating shell that keeps the interior frozen for over an hour. Inside, a high-grade stainless-steel tube maintains wine characteristics and ensures that taste is never altered. Comes with wine thermometer and air pump for thorough cleaning.
