Simply put, press one button for high-quality aeration. Aerating is a critical aspect of pouring a quality glass of wine and the Premium AirVi Automatic WIne Dispenser does it for you. The more that wine is exposed to oxygen, the more that its taste, flavor, and texture will be enhanced. Connect the silicone tube to the mouth of the main unit and insert it into the bottle with a firm push ensuring a secure fit. Once connected to the wine bottle, place your glass under the spout and press the button on the top and watch as your wine dispenses and is aerated. This process provides a first-class wine-drinking experience at an affordable price. This dispenser is designed to be spill/drip-free.
