Grgich Hills Estate is a Napa Valley winery that has been organically farming its vineyards since 2000.
They farm five estate vineyards without artificial fertilizers, pesticides or herbicides. They rely on wild yeast fermentation and in 2006, flipped the switch to solar power with 860 photovoltaic panels, covering 13,000 square feet of the winery’s red tile roof.
At peak production, the solar panels will provide almost 100 percent of the winery’s electrical needs while generating an estimated $70,000 in savings each year.
