Decant or not to decant

Do you ever decant your wine? I got a free decanter with a cosmetic purchase last year...but it's still in the box, just seems silly to get another dish dirty. But what do I know, apparently it does change the taste of the wine, so Spanish chef, Martín Berasategui, has designed a new bottle that decants without the decanter. Abadia da Cova, a Galician winery in the Ribeira Sacra will be one of the first to use it. Maybe now I´ll finally decant wine.
