The Sobon Estate winery started in 1989 when Leon and Shirley Sobon bought each other a second winery for their 30th wedding anniversary present. They purchased the historic D’Agostini Winery, one of the oldest in the state. This winery has been designated as California State Historic Landmark #762. This site was chosen not only for its historical winery, but also for its vineyards and vineyard land. The old vine Zinfandel was retained, and the other vineyards replanted with the best varieties and clones.
The Sobon Estate label launched the estate line of wines for the Sobon Family — the best wines from their own grapes. Over the years, Leon garnered many National and International awards for Sobon Estate and Shenandoah Vineyards wines. Both family label wines are distributed nationally, as well as internationally in Canada, Switzerland and Hong Kong. Leon is widely recognized as a leader in the wine industry and has actively participated in many industry boards and committees. He is also sought after as a judge for many prestigious wine-tasting competitions. Today … the winemaking and business aspects continue to be a family affair. Shirley is the Finance & Gallery Manager while Leon contributes his years of winemaking knowledge to every vintage. Sons Paul, Robert, and Son in-Law Tom Quinn continue the family tradition that began all those years ago.
