After an exhaustive search of cooler climate, higher elevation sites within Napa and Sonoma counties, David and Marla Jeffrey discovered a barren hilltop on Chalk Hill in Sonoma with 360 degree views of Mount St Helena, Knights Valley and the Russian River.

This bit of earth had everything David was looking for: a relatively cool climate, minimal frost exposure, maximum sunshine and hillsides with excellent drainage of the clay and loam soils over fractured shale and sandstone. Pooling their resources and soliciting assistance from friends and family, they purchased the site and quickly set off to begin planting.

Twelve acres of vineyard were planted in 2005 with each of the five classic red Bordeaux varieties broken out into specific blocks and matched to the unique components of the soils.
