Since our inception in 1974, Clos du Bois has been a champion of sustainability. We’re especially proud of our solar initiative, which utilizes over 4,000 solar panels to power our winery almost 100%, the equivalent of providing electricity to 164 homes a year. We’re water-conscious too. One acre of our almost 800 vineyard acres uses less water per year than a typical family of four.

We believe that creating a healthy ecosystem in the vineyard is critical for the vines to thrive. We pulled out some vineyards along the Russian River and planted native trees and shrubs along the banks to promote healthier fish habitats. We also restored a wetlands area at the winery to create a healthy environment for migrating birds and other creatures.


We believe that what you put into the earth comes back one hundred fold. We organically convert grape pulp, skins and seeds left over from the winemaking process into more than 7,000 cubic yards of compost each year that we return to our vineyards. By doing so, we turn a waste product into a natural nutrient for our vines.


Energy is a finite resource, and the sun can provide most of what we need. We installed four acres of solar panels to generate 85% of our energy needs, and our barrel room is cooled with an ice bank that allows most of the energy use to occur during the off-peak evening hours.
