Shenandoah Vineyards

Located in Plymouth, CA, Shenandoah Vineyards was founded in 1977 by Shirley and Leon Sobon. The couple relocated from Los Altos, California, where Leon had a successful career as a Senior Scientist at the Lockheed Research Lab. Leon’s passion for home winemaking inspired him to leave Lockheed and embark on a new journey as a winemaker.

The selection of the winery site in the Shenandoah Valley of Amador County was a well-researched decision. The Sobon family, including their six children, moved to the historic Steiner Ranch outside Plymouth, where they planted a vineyard and transformed the old stone garage into the winery. In 1989, they expanded their operations by acquiring the D'Agostini winery, leading to the formation of Sobon Estate.

Over the years, Leon has earned numerous national and international awards for the wines produced at Sobon Estate and Shenandoah Vineyards. Both family labels are distributed nationally and internationally, including in Canada, Switzerland, and Hong Kong. Leon is recognized as a leader in the wine industry, having served on various industry boards and committees, and he is frequently invited as a judge for prestigious wine-tasting competitions.

Today, winemaking and business operations remain a family affair. Shirley manages finance and the gallery, while Leon continues to impart his extensive winemaking knowledge into every vintage. Their sons, Paul and Robert, along with son-in-law Tom Quinn, uphold the family tradition that began decades ago, ensuring that Shenandoah Vineyards continues to thrive.
