At Gundlach Bundschu we define sustainability broadly, seeking not only to be responsible stewards of the land, but also to preserve this land for future generations of our family. There is nothing static about this view of sustainability—it requires innovation and action. We believe that preserving the unique ecosystem of Rhinefarm is essential to wine quality, as well as to the health of our family and business.
The introduction of beneficial predators, from owls and bluebirds to beetles and mites, and intensive pest monitoring allows us to minimize the use pesticides and herbicides. Cover crops contribute vital diversity and nutrition to the soils, and we utilize registered organic compounds and practices whenever possible. Vigilant management of our acute deficit irrigation program and water reclamation ponds promote conservation, recycling 70% of winery water. We continually seek ways to enhance environmental quality and make the most efficient use of resources.
In November 2008, two new solar arrays were installed on our property. The first, a 1.3 acre 80kw system, provides 60% of the winery power. The second, a "floatovoltaic" system, is the first of its kind in Sonoma County. The panels float on our ponds and provide 100% of the power to our water reclamation system.
