Both the door and wine cooling system play an important role in the proper preservation of the wine. This photo shows the elegant Coto style door installed by Wine Cellar Specialists. It is an exterior grade door constructed from wood, wrought iron, and glass. It is equipped with sealing components. The wine cooling system used was manufactured by US Cellar Systems. The evaporator was installed inside the cellar while the condenser was placed outdoors, resulting in a quiet operation.
