Producing world-class wines was the vision of two former aerospace engineers who in pursuit of their dream launched ZD Wines. The plan was to produce wines similar to those from the renowned Burgundy region of France using the Pinot Noir and Chardonnay winegrape varieties. In 1968, Norman deLeuze and Gino Zepponi pooled their resources of $3,000 apiece and applied for a winery permit. At that time, there had not been a winery permit issued in Sonoma County for nearly 20 years. The permit was issued in 1969.

Today, the de Leuze family continues to produce wines with a personal, hands-on approach. Over the years, all of Norman and Rosa Lee's children - Robert, Julie and Brett - have joined the winery staff. Robert's involvement began the day his father formed the winery and began crushing winegrapes. From the time he was 11 years old, Robert was never far behind Norman. In 1983, after years of practical experience and studying viticulture and enology at UC Davis, Robert became winemaker. At the same time, Norman stepped into the title of CEO.

The success of ZD Wines can only be attributed to the dedication and winemaking philosophy of the de Leuze family. As ZD Wines moves forward, the family continues to grow. Norman and Rosa Lee's grandchildren represent the 3rd generation to contribute their time and skills to the winery. In 1996 the de Leuze family purchased an historical, 33-acre vineyard in Carneros. Formerly owned by Irish immigrant Patrick Flanagan, the property is planted with 26 acres of Chardonnay. Another seven acres was planted with Pinot Noir which produced its first vintage in 1999. As the winery continues to grow, so does the vision of ZD Wines.
