Vineyards in Plymouth, CA, was founded in 1977 by Shirley
and Leon Sobon. They moved from Los Altos, California, where
Leon was a Senior Scientist with the Lockheed Research Lab.
Leon's gift for home winemaking led him to leave Lockheed
and begin a new career as a Winemaker.
The selection of a winery site in the Shenandoah Valley
of Amador County was well researched. Leon and Shirley and
their six children moved to the old Steiner Ranch, outside
Plymouth, CA, planted a vineyard, and converted the old
stone garage to the Shenandoah Vineyards winery. Sobon Estate
was formed with the purchase of the D'Agostini winery in
Over the years, Leon garnered many National and International
awards for Sobon Estate and Shenandoah Vineyards wines.
Both family label wines are distributed nationally, and
in Canada and Japan. 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 prestigeous wine tasting competitions.
Today ... the winemaking and business aspects continue to
be a family affair. Shirley is the lead Tasting Room, Gallery
& Museum Manager. Two sons and one son-in-law currently
work full time for the business: Tom Quinn in Sales and
Marketing, Paul Sobon as the Winemaker and Vineyard Manager,
and Robert Sobon as Business Systems Manager. Shirley and
Leon continue to be involved part time.
