CellarTracker is a website that stores information about wines and wine collections. Created in 2003 by Eric LeVine, a former Microsoft program manager, CellarTracker has grown to be one of the world's most comprehensive wine databases. CellarTracker is free to use and relies heavily on its users for data input, constantly increasing the number of tracked bottles as well as user tasting notes.
CellarTracker also has a donation option which gives access to a series of services through CellarTracker's cooperation with other online resources, such as Stephen Tanzer, Wine Market Journal and Jancis Robinson.
