When the Orbital Wine Decanter is removed from its stainless steel base, the shape of the bottom of the Orbital Decanter allows it to roll gently from side to side to aerate the wine. The wine within is able to breathe while the sediment stays in the bottom. The Orbital Decanter also comes with a tight-fitting crystal stopper to prevent spills. 60 ounce capacity, 10-1/2" tall (with stopper). 7-1/2" wide.
