Oxygenates your wine as you pour. Opens up your wine to the optimum amount for full flavor. Tip: Many wines will improve their flavor and aromas by allowing them to breathe. This is especially true of red wines, which will benefit most. It is important to allow as much surface area of the wine to be in contact with the air to get the full effect of aeration-use wide mouthed, wide bottomed decanters for example. If pouring directly from the bottle, use glasses that will allow the wine to fall as much as possible to help the aerating process. Drink responsibly.
