The device narrows like an hourglass, speeding up the wine and creating a vacuum which draws air into the tube, so oxidising the wine. This also makes it possible to decant wine by the glass. Made of plastic, rustproof steel and rubber. Length: 9.5 cm (4” approx.), Ø 3 cm (1” approx.), weight 60 g.
There are two reasons why red wine should be “decanted”. Apart from removing unwanted sediment, wine is decanted to introduce oxygen so the flavour can develop and it is ready to drink. This is achieved by pouring the wine into a decanter, but the process can be speeded up by using a decanting attachment.
