Sharing Uncommon Ground

The greatest vineyard sites in the world are, at first glance, not where one would expect an agricultural product to flourish. They are sites that challenge the very survival of the vine.

Seghesio's collection of unique sites in North America's finest grape growing regions are not accidental, but the choice of four generations of the family's winemakers. With stewardship of these sites for over a century and a new generation's passion to grow some of the world's finest grapes, Seghesio Family Vineyards is honored to share uncommon ground.

HOME RANCH, RATTLESNAKE HILL, & SISTERS In 1895, after a decade of experience with the climate and soils, Edoardo Seghesio chose the western bench of Alexander Valley as his stake In the New World and planted his first vineyard to Zinfandel. The absence of marine influence marks this growing appellation. Long, warm days create an environment that enables noble red varietals to excel. With only 8-16 inches of topsoil and clay soils with varying underlying layers of basalt, sandstone, and serpentine rock, vines have a difficult time surviving. The resultant lower yields produce grapes with incredible concentration.   Total Acreage: 190 acres (primarily Zinfandel with Petite, Cabernet, Sangiovese, Barbera, Aglianico) Vineyard purchased in 1895
RIVER ROAD Located on the eastern bench of northern Alexander Valley, River Road is the warmest of our vineyards. Yolo and gravelly, sandy loams are the result of this vineyard's proximity to the Russian River.   Total Acreage:56acres (100% Zinfandel) Vineyard Purchased in 1942.
LONE OAK Climatically, Alexander Valley tends to be warmer as one moves north up the valley. Our Lone Oak Ranch is in an area that is slightly cooler than our Home Ranch. The well-drained soils here are comprised primarily of gravel (Yolo) based loams.   Total Acreage:25 acres (100% Zinfandel) Vineyard Purchased in 1971.
CORTINA Nestled in the heart of Dry Creek Valley, Cortina's climate reflects both coastal and inland influences. Mornings shrouded in fog are followed by long hours of sunshine. The soils at Cortina are diverse, consisting primarily of loam (Yolo) interlaid with gravelly loam (Cortina) ideal for Zinfandel.   Total Acreage: 56 acres (primarily Zinfandel) Vineyard Purchased in 1957.
SAN LORENZO San Lorenzo was planted in the early 1890s, making it the oldest vineyard we farm. Ideal for Zinfandel, San Lorenzo’s bench lies in the Southeast Alexander Valley above the fog layer and is rooted in clay loams.   Total Acreage:32 acres (Zinfandel and Petite Sirah) Vineyard Purchased in 1896
KEYHOLE RANCH Located in northern Russian River Valley, this vineyard's microclimate is tempered by cool coastal breezes and frequent summer-morning fog. These climatic conditions provide an optimum growing environment for Pinot Noir, Chardonnay, Pinot Grigio, and Arneis. The soils are composed of gravel and clay loams.   Total Acreage:72 acres (Pinot Noir, Pinot Grigio, and Arneis) Vineyard Purchased in 1961
