(NBBJ) - Sonoma-based wine company Don Sebastiani & Sons upgraded its south Napa winery, now called Steelbird Cellars after birds that populate the area, with new bottling capabilities, high-tech treatment of water to reduce chemicals used, energy-efficient lighting and “showcase” offices and client reception area. “If there was an end-tier consumer who wanted a private tasting, I was embarrassed to show them those offices, and now it shows the sex appeal of our brands,” said Donny Sebastiani, president and chief executive officer. The cost of this project is being kept private too.
