Winemaker Notes




Shenandoah 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 1989.

Originally a source of oenological sustenance for gold-seeking miners of the mid-1800s, the Sierra Foothills was the first region in California to produce wines from European grape varieties. Located between Sacramento and the Nevada border, this area’s immigrant settlers chose to forgo growing the then-ubiquitous Mission grape and instead brought with them superior vines from the Old World to plant alongside mining camps.
Zinfandel has been the most important variety of this region since its inception, taking on a spicy character with brambly fruit and firm structure. Amador and El Dorado counties, benefiting from the presence of volcanic and granite soils, are home to the best examples. Bold, robust Rhône Blends and Barbera are also important regional specialties.

Full and silky in body but also charmingly crisp, Roussanne is native to the Rhône Valley of France. It is responsible for some of the finest Northern Rhône white wines. Roussanne adds richness and acidity to Marsanne’s soft, fruitiness, making age worthy and highly respected whites. Somm Secret—Roussanne takes its name from the French word, roux, meaning rouge or red because of the berry’s pink glow. In California, virtually all of the 339 acres of Roussanne come from true clones brought over by Tablas Creek and John Alban.
