The Estate's sixty acres of vineyard grow at elevations of 900 to 1100 ft on east, west and south facing slopes as well as on the valley floor. Soils vary from clay-loam to shale. After purchase of the vineyard property, the Eiseles began an extensive redevelopment and restoration of both the vineyard acreage and the riparian corridors. Presently 72% of the vineyard is planted in Cabernet Sauvignon, 12.5% Merlot, 10.5% Cabernet Franc, 3% Semillon and 2% Sauvignon Blanc. Seven different Cabernet clones have been incorporated to provide diversity of flavor.

Over the past 35 years the Eiseles have enriched the vineyard soils through use of organic farming practices. No herbicides, pesticides or chemical fertilizers have been used. The vineyard is certified as organic by both the California Certified Organic Farmers and the California Department of Food and Agriculture. It has been set back from the property's creeks to substantially increase riparian vegetation. Oaks and other native tree species have been planted on the creek banks to prevent erosion. Throughout the property creeks and associated riparian areas have been protected and enhanced.
