The Centellino is a unique top-of-the-bottle wine decanter that double aerates your wine in seconds. The first time as the wine flows down the inside of the glass bulb. At this point the sheet of wine is paper thin and can breathe in Oxygen and exhale the carbon dioxide. Then during the pour, the wine gets bubbled and mixed with air. This double aeration process both mellows the feel of the wine and also fully blooms and enriches the bouquet and flavor of every glass of wine. The old style decanters only hold one bottle of wine and take at least an hour to fully aerate. With the Centellino, you can have as many guests and serve as many bottles as you like and every serving will be aerated to perfection. The Centellino is so effective, cheaper wines taste like expensive wines and really good wines reveal all their complexities and profiles.
