Eight miles north of San Pablo Bay, the Bundschu family's 158 year-old vineyard wraps around the southwest slopes of the Mayacamas Mountains. The terrain features steep, southwest-facing hillsides of shallow, rocky soils of volcanic ash and alluvial wash. Pervasive maritime breezes and long daylight exposure allow fruit to develop intense concentration while retaining vibrant structure. A portion is sourced from warmer vineyard sites in Sonoma Valley to add lushness to the mid-palate.
