We strive to create a self-sufficient and balanced agricultural ecosystem, embracing diverse plant and animal populations. On our Ranch, we mindfully consider the sustainable use of resources while tending the soil, supporting the flora and fauna dependent on its health, and tapping the solar energy that powers the growth cycle to maximize sequestration of atmospheric CO2 in our farm products and fertile soils. Our orchards and gardens are maintained in accordance with organic standards and are certified by the California Certified Organic Farmers (CCOF.)
Active fertile soil is the foundation of our approach to farming. To enrich our soils, eliminate off-ranch waste, and reduce water consumption, we produce our own organic compost from the by-products of olive oil and wine production, farming, and maintenance of the Ranch landscape and gardens. The olive paste that remains after oil extraction and the wine lees are mixed with livestock manure and plant materials for effective composting. The liquid waste, or olive fruit water, is used to maintain compost moisture. Compost helps develop the organic matter content of our soils, enhancing the quality and productivity of our plantings while sequestering tons of atmospheric CO2 in every acre of fertile ground. Our chickens forage on fenced pastures for insects and plants and their manure is used in our compost. Sheep seasonally graze the orchard cover crop, facilitating nutrient cycling and soil fertility development. Their work reduces the need for fossil fuel-powered mowers and synthetic fertilizers.
In June 2009, we installed a 225 kW Norwin windmill, the first privately-owned turbine of its size in Marin County. The windmill tower is 97 feet tall, with 40-foot long blades. Its hilltop location was chosen specifically for its ability to harness adequate wind and avoid significant impact on wildlife. The windmill reduces our greenhouse gas emissions by an estimated 110 tons of CO2 annually and meets about half of our electrical energy needs.
Our unique vineyard location in west Marin County’s Petaluma Gap offers us distinct climate and varied soil types that are conducive to cultivating our estate plantings. The region’s microclimate guarantees that our vineyards and olive orchards are often shrouded in fog during the early morning hours and evenings, helping ensure steady, gradual fruit maturation. While the day’s temperature is pleasant, we experience dramatic diurnal swings with nighttime temperatures dipping low. Our site takes full advantage of this “wind tunnel” effect resulting in smaller vineyard yields, moderate sugar levels, and grapes with optimum levels of acidity.
