Z is for ZD Wines, which is family-owned and operated by three generations of the deLeuze Family. It is located at 8383 Silverado Trail in Rutherford. ZD was founded in 1969 by aerospace engineers Norman deLeuze and Gino Zepponi, along with their families. Their founding concept was to produce world-class chardonnay and pinot noir reminiscent of France’s renowned Burgundy wines. They achieved this endeavor by sourcing from the cool Carneros regions of Napa and Sonoma. The ZD Wines brand highlights the initials of the founding partners’ last names, but it also symbolizes the term Zero Defects, an acronym for the quality control program Norman and Gino worked under while designing rockets at AeroJet, a rocket propulsion manufacturer in Sacramento. Today the winery produces chardonnay, pinot noir and cabernet sauvignon.
