The Avanti Wine Aerating Pourer filters, splits and oxygenates wine as it pours. When wine is poured through, its internal design increases wine's velocity but decreasing its pressure. The pressure difference creates a vacuum that draws in fresh air which is mixed with wine for perfect aeration. Simple to use, just insert the wine pourer into the bottle and pour wine through. For maximum aeration, ensure to tilt bottle diagonally when pouring. You will notice and hear the bubbles flowing through the wine indicating the combination of wine air, enhancing the bouquet and flavour instantly.
