This spout instantly chills wine by as much 15º F. Storing the spout in a freezer freezes its internal stainless steel tube, and when wine is poured through the spout, the 2'-long, coiled tube immediately cools room-temperature red or white wine. The spout's shell acts as a thermos, keeping the tube cold enough to chill an entire bottle of wine. An air inlet on the spout can be covered with your thumb to slow down the flow rate, allowing wine to chill longer inside the spout--ideal for pinot grigio or similar varietals that are typically served cold. The spout fits securely inside the neck of a bottle like a cork, allowing confident pours. Freeze for at least six hours prior to use. 8" L x 2 1/2" Diam. (11 1/4 oz.)
