The Wine Bottle Aerator lets you cool your wine from the inside, while the drip-free pour spout with built-in aerator ensures a constant flow of wine so you don't waste a drop! Your wine is allowed to breathe perfectly for optimum flavor. To use, store the cooling stick in the freezer for about an hour until the hermetically sealed cooling gel freezes, then screw the vent vent to the cooling stick. After pouring some wine from the bottle, place the wine cooler in the bottle and enjoy up to two hours of perfectly chilled wine. To clean, simply rinse the cooling bar and spout with warm water after each use. The Wine Cooler Aerator has a stylish design to fit all bottle sizes. Made of BPA-free acrylic and premium stainless steel, the Wine Cooler Aerator will never change the flavor of your wine.
