This appellation spans 2,300 acres (931 ha) and was granted AVA status in 1982.
The soil in the region is composed of foundations of limestone and dolomite with sandy, gravelly loam above.
[3] The only vineyards in the Lime Kiln Valley AVA are owned by the Enz Family.
Currently there are 40 acres of vineyards, including a 15-acre parcel of head-trained Mourvedre that was originally planted in 1922.
In 2007, the Enz Vineyard first planted in 1895 and now growing grapes for Kenneth Volk Vineyards was discovered to be planted with the nearly extinct Bordeaux variety Gros Verdot instead of Cabernet Pfeffer as originally thought.
