Terra d'Oro

Sierra Foothills Zinfandel and rare varietals from Amador County.

Terra d'Oro operates in Amador County, in California's Sierra Foothills—a region defined by warm days, cool nights, and old-vine vineyards planted to varieties that thrive in its mineral-rich soils. The winery's portfolio centers on bold, structured wines. Its Zinfandel Port 10 Year, made from Zinfandel grapes, represents a fortified expression of the region's signature varietal. The Teroldego, an Italian variety rarely seen in California, brings alpine structure and mineral precision. The Petite Sirah rounds out the core offerings with the dark fruit density and tannin architecture the Sierra Foothills is known for. Wine Enthusiast has rated these wines, reflecting their technical depth. Terra d'Oro's focus on less-common varietals alongside regional classics positions it within Amador County's tradition of experimentation—a place where winemakers work with both heritage grapes and unexpected cultivars to express the terroir's distinctive character.
