Everyvine

Everyvine was created by cartographer Thomas Jordan as a crowd-sourced mapping site for wine-centric locavores who want to know exactly where their wine comes from. Producers can parcel- and block-specific information such as grape varieties, clones and root stock planting dates and trellis methods. You can search by region or grape variety. I conducted a few random state searches and the quality or clarity of information was dependent on what the producers chose to upload. Most comprehensive is California's Sonoma County, Jordan's one-time home.
