Halter Ranch completed a new state-of-the-art winery in 2011 utilizing a multi-level gravity flow system. Gravity flow allows the winemaker to handle the fruit in the gentlest way possible, by preventing the pumping of skins and seeds. The winery’s night air-cooling, natural lighting, and 20,000 square feet of caves are integral to its energy efficiency and sustainability. Cool mass provided by the limestone in the hillside, along with concrete in the walls of the cave, stabilizes the temperature at 56 degrees while maintaining ideal humidity for wine storage. As of 2020 100% of the winery's energy needs are covered by the 1,026 solar panels on the property, the solar system is estimated to reduce greenhouse gas emissions by 522 metric tons annually.
