In 1977, Leon Sobon -- a research scientist from Los Altos -- and his wine Shirley came to Amador County and moved to the former Steiner Ranch to become vintners. They planted vineyards, converted the old garage into a winery, and produced 1200 cases their first year of production. Today, Shenandoah produces two Zinfandels, a Black Muscat, Barbera, Cabernet Sauvignon, a Cab/Syrah blend and Sauvignon Blanc. They also produce Sangiovese and a Sangiovese/Zinfandel blend.

The Sobons also own Sobon Estate, a few miles to the east. Leon and son Paul are the winemakers, while Robert -- another son -- also works in the business. Son-in-law Tom Quinn is in the sales and marketing area.

Annual production of the two wineries, including Sobon Estate, is around 30,000 cases.
