Our Sustainability Program 

Celebrating three generations of environmental leadership in the wine industry, our passion extends beyond the wines themselves to the place we live and work.  We firmly believe that the only way to do this is by keeping our vineyards healthy and thriving.

Our vineyard has been certified Napa Green Land since 2006.  The Napa Green Land program involves a comprehensive evaluation of farming practices with a particular emphasis on protecting fragile riparian areas.  In July of 2009, we became just the 15th winery in the Napa Valley to be certified a Napa Green Winery, and in 2012 we were awarded the International Award of Excellence in Sustainable Winegrowing by the Botanical Research Institute of Texas (BRIT®).

Our family is strongly committed to being good stewards of the land, responsible neighbors, and enlightened employers.  Some of our sustainable farming practices include:
 

  • Solar arrays produce clean energy for our operations – preventing the emission of 77 tons of greenhouse gases each year
     
  • Coupling this clean energy with our all-electric ATV allows for vineyard scouting with zero emissions
     
  • Our entire fleet of tractors runs on bio-diesel produced from soybeans which has much cleaner emissions than petroleum diesel
     
  • Employing deficit irrigation techniques to curtail our water usage
     
  • The water we do use for irrigation comes from sustainable sources including recycled winery process water, captured storm water runoff, and subsurface vineyard drainage
     
  • Recycling all pomace (skins, seeds, stems) to use as compost in our vineyards
     
  • Harvesting in early morning rather than using power to cool the juice mechanically
     
  • Cover crops are planted to sequester atmospheric carbon, enhance soil fertility, limit erosion, control vine vigor, and attract beneficial insects
     
  • Practicing natural pest control by installing barn owl and bat boxes
     
  • Restoring riparian areas to maintain and enhance aquatic and wildlife habitats
