The ice pocket in a decanter is a popular way to serve cold wine. The ice sits down in the decanter surrounded by wine thereby keeping it chilled. It's on the outside of where wine is stored inside the decanter so that the ice doesn't dilute the wine. Talented South American glass blowers create handmade decanter. It's a piece of art! These are free form pieces, not made from molds, but wonderful organic shapes that are thick and hefty. Best of all, the glass is recycled from old windows, automobile glass, and all sorts of bottles. Each design is one-of-a-kind, and yes, as always, you can count on unique variations in each piece. For after all... this is no ordinary piece of glass!
