Bart Hansen began his career in the wine industry as a crush worker during harvest time at Kenwood Vineyards. While at Kenwood Vineyards, Hansen worked his way up to Cellar Master; after working there for fourteen years, he took the position as Assistant Winemaker at Benziger Family Winery. It was there that Hansen helped make wine for the Benziger Family Winery label, as well as the Benziger family's smaller label—Imagery Winery—which produces limited production, lesser known varietals. In 2007, Hansen left the Benziger family and went back to his roots as Cellar Master for Lasseter Family Winery, so that he could channel his winemaking energy into producing his own varietals for his own winery—Dane Cellars.
After twenty-one years in the wine industry, Hansen founded Dane Cellars in 2007 and sold the first Cabernet Sauvignon and Zinfandel vintages in 2008, with fruit sourced from local Sonoma Valley vineyards. Now, seven years later, Hansen is producing four varietals: Cabernet Sauvignon, Zinfandel, Syrah, and Chenin Blanc. There are two Zinfandels, each made with fruit sourced from their own vineyard; one of these vineyards produces fruit from 60-80 year old vines. All of the fruit is sourced from vineyards in the Sonoma Valley AVA, except for the Chenin Blanc—which is sourced from vineyards in the Clarksburg AVA in Yolo County.
For the past seven years, Dane Cellars has not had a tasting room and the wine has only been sold at local restaurants—by the glass and bottle—markets, and wine shops, as well as online through the Dane Cellars website. This keeps the small production wine—each varietal produces less than 200 cases annually—very exclusive. As a result, the wine has become highly sought after.
