The Vacu Vin Wine Aerator adds a new dimension to wine drinking. The design of the product slows down the wine flow into the glass, allowing it to take up extra oxygen, so enriching the taste. As the detachable top is transparent you can follow this process. After use, rinse the Wine Aerator under the tap and store it around the neck of your wine bottle. A great gadget for the wine enthusiast and a fine addition to your wine accessories.
