Twisted Oak Winery is a family-owned boutique winery in Vallecito, California specializing in wine made from grape varieties native to the Mediterranean regions of western Europe. The winery is located on a hilltop at 2280 ft (695 m) above sea level in the foothills of the Sierra Nevada Mountains, and most of the grapes for the wines are sourced from nearby vineyards in Calaveras County. The winery name and logo design are derived from a California Blue Oak tree on the property. History The winery was founded by Jeff and Mary Stai, and opened in 2001. The Stais hired Scott Klann, a native of Murphys, who had over a decade of experience in the Calaveras County wine industry, as Twisted Oak's first winemaker. The original 10 acre (4 ha) vineyard on the 120 acre (48.5 ha) property was planted to Tempranillo, Grenache, and Graciano, grape varieties native to the Mediterranean regions of France, Spain and Portugal. The decision to plant Iberian grape varieties, uncommon in California, was in part due to a dinner that Stai and Klann attended at a Spanish restaurant in which they tried many Spanish wines that impressed them. The winery's first vintage was 2002, when they produced 10 different wines, all made from purchased grapes. The wines were produced in a custom crush facility at the Olde Lockeford Winery in the town of Lockeford, California. The first vintage began a tradition of naming wines with exclusively non-alphabetic symbols (in a style often used to replace profane words in written English), such as the *%#&@!, a red blend of Mourvedre, Syrah, and Grenache grapes, and the %@#$!, a white wine made of Marsanne and Roussanne grapes (introduced two years later). The unusual wine names were inspired from the owner and winemaker's frustration at being unable to come up with a good name for the red blend. The unique wine labels have been the subject of doctoral research in communications. The 2002 Calaveras County The Spaniard would be well received by wine critics, scoring 92 points in a review for Wine Enthusiast magazine. With their own winery facility still under construction, Twisted Oak's 2003 vintage was produced at the facilities of Hatcher Winery in the nearby town of Murphys. The winery opened a tasting room on Main Street in Murphys in July 2003. The tasting room is located in the childhood home of Albert Abraham Michelson, the first
