The site is at the junction of Summit Road and Loma Prieta Avenue.

David and Anne Moulton began development of the Estate vineyard in 1973.

Soils are a complex mixture of loam and shale due to the close proximity to the San Andreas Fault.

Initial plantings were to Chardonnay and Merlot, with Pinot Noir added in 2002.

Cultivation and spraying are done with heritage Cletrac tractors; pruning, seasonal operations and picking are all done by hand.
