WHY AERATE WINE? When wine is bottled, it is secured with an airtight seal in order to remain in the state the winemaker intended. Over time, the tannins break down, creating a smoother, more drinkable wine, which is one reason why older wines are more expensive and prized. Aerating a young wine mimics the ageing process, creating a smooth, delicious wine in just a few minutes. Yup, that’s the beauty of aeration.
