Blue Rock is located in the northern Alexander Valley near the town of Geyserville. The vineyard, consisting of 43 acres, was replanted in 1982 to the 5 Bordeaux varietals. In 1993, an additional 3 acres of Beaucastle-clone Syrah were planted in the hills. The ancient olive trees are beautiful and still produce tiny amounts of organic oil.

Bordeaux varietals are adaptable to many soil and climate conditions but develop great character and longevity in relatively few locations. Blue Rock, nestled in the western hills between the Dry Creek and Alexander Valleys, is blessed with a Maritime climate consisting of cool mornings and warm days that make it one of those special places where Bordeaux varietals develop clarity and finesse. The vineyard elevation is between 300 and 400 feet above the valley floor. As a result, the soils are hallow,
 

generally no more than 18 inches deep, before the roots hit a layer of clay and serpentine rock. The vines are small, tightly spaced in the replanted sections, and the yields average a modest 2.5 tons per acre. Further complexity is derived from the multiplicity of root stocks and clones.

The name Blue Rock comes from our soils, which are studded with blue pebbles, rocks, and boulders of serpentine. The serpentine rock defines the unique flavor profile of the vineyard, as serpentine naturally devigorates the vines and reduces the yields to very low levels. Today, the very best vineyards are planted on devigorating rootstocks in order to improve the flavor and density, something that comes naturally to Blue Rock.
