From El Dorado to San Diego and from Shenandoah Valley to the Mendocino coast, the Historic Vineyard Society has identified 224 historic vineyards in 29 appellations throughout the state.

However, only 68 of those vineyards – fewer than a third – have been registered with the Society. Of 26 historic vineyards in Napa County only seven are registered. Of 23 listed in Sonoma County, 14 are registered.

Online registration is easy at To qualify as historic, a vineyard must be currently producing a California wine, have an original planting date no later than 1960 and have at least one-third of existing producing vines traced back to its original planting date.
