Our Vineyards

Farming in Sonoma since 1927

Our vineyards are like family heirlooms. They all have a story, an emotional connection.

– STEVE SANGIACOMO

Our family has always felt a deep connection to the land — most especially through farming.
It all began in Genoa, Italy where a good day’s work for our grandfather Vittorio Sangiacomo started and ended in the field. He voyaged to America in 1913 on the advice of our great grandfather and got his first job at age 17 in the vegetable fields at Bay Farm Island in Alameda County, California. Shortly thereafter he began working in the scavenger industry in San Francisco where he later successfully launched his own business. But he longed to return to working the land and in 1927, he purchased a 52-acre fruit tree ranch in Sonoma Valley.  Today, we call that the Home Ranch.

For decades our family has been dedicated to farming in Sonoma County. We are grapegrowers with a passion for sustainability and stewardship. Year by year we have gathered knowledge and continue to pursue perfection in farming each and every row of our vineyards. Through research, trial and error in the field, and critical evaluation of the resulting wines, we have learned how to select the right varietals, clones, and rootstocks, as well as row spacing and orientation for more than 100 individual sites. This approach, paired with the appropriate pruning, irrigation, canopy management, and nutrients is what enables us to tease an extraordinary range of flavors out of our Chardonnay, Pinot Noir and Cabernet Sauvignon grapes. At every step of the way we seek to produce the highest quality fruit with the lowest environmental impact possible.

Home Ranch

The Home Ranch is just what you might imagine; the heart and soul of our family business.

Location: The southern end of Sonoma Valley, two miles south of the historic Sonoma Plaza.  Our Carneros vineyards are influenced by the cooling effect of the Pacific Ocean and a combination of summer fog, warm days, and a long growing season.

Appellations: Carneros and Sonoma Coast

Vines: First planted in 1980, this 110-acre ranch is primarily Chardonnay.  We harvest from a block of exclusively Old Wente clone for our vineyard designate bottling of Home Ranch Chardonnay.  Certified Sustainable by the California Sustainable Winegrowing Alliance.

Soil: Zamora Silty Clay. The soil is a deep, fine gravelly silty clay derived primarily from the Sonoma Creek and Schell Creek drainages.

Green Acres Vineyard

One of the most highly-acclaimed vineyards, desired for its distinctive character and intensity of the grapes.

Location: The southern end of Sonoma Valley, two miles south of the historic Sonoma Plaza.  Bordered by Sonoma Creek to the east and Fowler Creek running through the middle. Our Carneros vineyards are influenced by the cooling effect of the Pacific Ocean and a combination of summer fog, warm days, and a long growing season.

Appellations: Carneros and Sonoma Coast

Vines: Planted in 1969, Green Acres is the very first vineyard ever planted on Sangiacomo soil.  This 162-acre ranch is home to more than 20 different clone and rootstock combinations.  For our vineyard designate selection, we harvest exclusively Old Wente Clone and Hyde selections. The Heritage Block, planted in 1969 to Old Wente Clone on St. George rootstock is our most beloved 5 acres of grapevines, first placed by our ancestors.  These rugged old vines are remarkable in their intensity and concentration of flavors.  Certified Sustainable by the California Sustainable Winegrowing Alliance.

Soil: Zamora Silty Clay. The soil is a deep, fine gravelly silty clay derived primarily from the Sonoma Creek and Fowler Creek drainages.

Amaral Vineyard

Named after the Portugese family who originally farmed this land for pasture and hay.

Location: Nestled in the southwestern foothills of Sonoma Valley.  Our Carneros vineyards are influenced by the cooling effect of the Pacific Ocean and a combination of summer fog, warm days, and a long growing season.

Appellations: Carneros and Sonoma Coast

Vines: First planted in 1984, this 110-acre ranch is home to Chardonnay, Pinot Noir and Pinot Gris. Fully replanted in 2003 with fifteen clone an rootstock combinations. Clones 667 and 777 are harvested for our Sonoma Coast Pinot Noir. Certified Sustainable by the California Sustainable Winegrowing Alliance.

Soil: Clearlake Clay Loam and Hair Clay loam. Soils are restricted and yields are low.

Roberts Road Vineyard

Amongst the most prestigious vineyards cultivated by our family.

Location: Located at the base of Sonoma Mountain at the far northern edge of the Petaluma Gap.  The fog from the ocean near Bodega Bay pours into this region first and exits last. Therefore most of the day is spent in fog and clouds which produce extremely small berries and low yields.

Appellations: Petaluma Gap and Sonoma Coast

Vines: A pioneer vineyard in the region, first planted by our family in 1999.  This 130-acre ranch is exclusively Pinot Noir and Chardonnay with over 20 different clonal selection and rootstock combinations. Certified Sustainable by the California Sustainable Winegrowing Alliance.

Soil: Well-drained cobblestone soils were developed from the nearby Copeland Creek which meandered over the property for centuries.

Fedrick Vineyard

Represents our family’s exploration into the Petaluma Gap region.

Location: Nestled in rolling hills in the southwestern end of the Petaluma Gap appellation.  Our vineyards in this region are influenced by the cooling effect of the Pacific Ocean and San Pablo Bay.  Most of the day is spent in fog and wind, which produce extremely small berries and low yields.

Appellations: Carneros and Sonoma Coast

Vines: First planted in 2000, Fedrick Vineyard was one of the first to be replanted to vines during a re-birth of the Petaluma Gap region. Thirty years later, this appellation is widely recognized as producing some of the finest cool-climate grapes in California. The 60-acre vineyard is planted to eleven different clone and rootstock combinations, with a variety of Chardonnay and Pinot Noir selections sought after for their depth and balance.  Clones 667 and 777 are harvested for our Sonoma Coast Pinot Noir. Certified Sustainable by the California Sustainable Winegrowing Alliance.

Soil: Clearlake Clay Loam, Reyes Silty Clay Loam, Hair Clay Loam and Diablo Clay Loam.
