The winery's own winemaking facility and estate tasting room were completed in July 2004, and included a 300 ft (91 m) cave for barrel storage. The winery's first vintage at the Vallecito hilltop facility was 2004, and it produced 14 different wines. Seven of the wines carried the Calaveras County appellation designation, and five were sold under the Sierra Foothills AVA appellation designation. Some of the wines were estate grown and others were made from grapes grown in the Tanner and Dalton Vineyards of Calaveras County or the Sumu Kaw Vineyard in El Dorado County. In the vintages since the winery's completion, Twisted Oak has bottled between 8,000 and 14,000 cases of wine. The winery facility is designed to support the production of 13,000 to 14,000 cases of wine at capacity.
