The Sierra Foothills growing area was among the largest wine producers in the state during the gold rush of the late 1800s. The local wine industry enjoyed great success until just after the turn of the century when fortune-seekers moved elsewhere and its population diminished. With Prohibition, winemaking was totally abandoned, along with its vineyards. But some of these, especially?Zinfandel, still remain and are the treasure chest of the Sierra Foothills as we know them.
