Our Vineyards
The Heart of our Vineyard Designate Wines
Sangiacomo Roberts Road Vineyard
From Sonoma’s long respected family growers comes the fruit for our Sangiacomo — Roberts Road Vineyard Pinot Noir. Planted in 1999, Roberts Road Vineyard lies in the newly designated (December 2017) but long revered Petaluma Gap AVA. For nearly half the day the vineyard is shrouded in fog and also influenced by coastal breezes, lending itself to slow, even growing and fruit development.

Wildcat Mountain Vineyard
Planted in 1998 by vintner Steve MacRostie and partners, Wildcat Mountain is a hilltop vineyard (700 feet above sea level) often in the middle of the fog and vigorously challenged by the wind. The soils are rocky and well-draining. The nearby San Pablo Bay contributes to the overall terroir and climate. All together these elements make the vines struggle and produce distinct flavors in the finished wine.

Las Brisas Vineyard
Las Brisas Vineyard, part of the Mahoney Estate, translates to “the breezes” and sits on the Sonoma side of the appellation. It is named for the winds that drive morning fog from the vineyards and bring in cooling breezes in the late afternoon. The predominantly clay soils of Carneros are shallow, this combined with the influences of the nearby San Pablo Bay, yield remarkable fruit year after year.

Landa Vineyard
Many of our Rhône varieties are sourced from Landa Vineyard, located in the low eastern foothills of the Mayacamas, tucked away just one mile from the town square in Sonoma. This site experiences warm days, and is protected from winds. This, combined with the cool valley nights, makes the vineyard ideal for slow, even ripening.

Bismark Vineyard
Bismark Vineyard is located in the Mayacamas Mountains high above the city of Sonoma, in the sub-appellation of Moon Mountain District. The soils in this vineyard are rocky and well-draining. Sitting at an elevation high above the fog line at 2100 feet, this steeply sloped vineyard benefits from cooler air temperatures, yet intense sun light, adding to the depth of this wine.
