Also known as a cellar master, most wineries employ these people to look after the wine once it's been made. There's a lot more to storing and aging wine than just putting it in a barrel. A cellar manager has to be extremely precise with the conditions in which the wine is stored and take regular, daily tastings of each batch to make sure it's where it should be. The cellar manager works closely with the vintner and typically has a few employees under her, called "cellar rats." Starting out as a rat is a great way to work your way up to manager.
