We’ve all experienced it; purchased a nice bottle of white and then realized it’s not chilled to perfection before the dinner guests arrive. The Ravi instant wine chiller can instantly cool any wine by as much 15 degrees F simply by attaching the apparatus and pouring. First you’ll need to make sure it’s frozen for more than 6 hours, then as the wine passes through its internal coil system it instantaneously chills the wine. A small air inlet can be covered to slow the pouring rate and increase the cooling time, which is apparently good for up to 1 bottle of wine. Your for $36.
