This wine is composed from two world-class vineyards owned by the Sangiacomo family, one of Sonoma County’s original--and leading--grape-growing families. Located near the Petaluma Gap, the Roberts Road Vineyard is characterized by cool temperatures and coastal fogs. The block is planted with the Dijon clone 95, a variety ideally suited for even the coolest climates and which adds a sparkling minerality and a green apple component to the blend. The Kiser Vineyard is situated farther inland in southwestern Sonoma and is planted with the Wente clone, a cultivar that contributes bright acidity balanced with the concentrated and weighty stone fruit flavors.
