CellarTracker

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 was created in 2003 after creator Eric LeVine, then a programmer at Microsoft, had made the program for himself, tracking his wine.

The CellarTracker concept proved popular and over the years it out-paced other similar resources, such as Cork'd, while increasing cooperating with other wine-related services.

[citation needed] An early contributor was US wine critic Stephen Tanzer who offered his scores to donating members of CellarTracker.

[citation needed] In early 2010, Eric LeVine launched a sister site for CellarTracker, called GrapeStories.

The user is supposed to search for the wines in his cellar on CellarTracker's database and then enter number of bottles and price (optional).
