The Bundschu family's 150+ year-old vineyard is located on the southwestern slopes of the Mayacamas Mountains, just eight miles north of San Pablo Bay. The terrain below 150 foot elevation features gently sloping Huichica clay loam soils with gravel deposits and cooler growing conditions that deliver minerality and focused acidity. Wines grown in these blocks bear the Sonoma Coast designation to reflect their cool climate character. Eleven acres of Heritage Selection vines, planted in 1969, were harvested in two lots and bring spice and floral notes. Nine acres of clone 47 vines, planted in 2008, were harvested in three lots and provide fresh fruit flavors.
