An appliance for decanting wine developed by the Italian restaurateur Damiano Miniera (pictured below). It consists of a small glass balloon, whose tube is placed on the bottle. This allows the quantity of 100 millilitres to be filled into the balloon, whereby the wine comes into contact with an extremely high amount of oxygen (air). Now (the device is still on the neck of the bottle) the wine from the balloon is poured into the glass. The video (click to view) clearly shows the process. Branded systems working on a similar principle are Decantus and Venturi tube.
