Our signature wine, Hillside Select, is sourced from the slopes of an amphitheater-like structure of rock, where thanks to a series of knolls and outcroppings some vineyard blocks receive southeastern sunlight, while others receive southern, or western exposure. Each afternoon cool breezes from San Francisco Bay channel into our box canyon. "The consistent heat helps to achieve ripeness, while the evening chill retains acidity," says Doug Shafer.
Meanwhile, the rock-choked volcanic soil often goes no deeper than 18 inches before hitting weathered bedrock. With the quick runoff this offers and a lack of plant nutrients, the struggling vines produce clusters with small, intensely flavored berries.
