Bonterra Single Vineyard, Cultivating the Future

Each offering in the trio of Bonterra Single Vineyard wines is an exquisite portrait of its origins. Estate grown, hand-harvested and organically-grown, the grapes from Bonterra’s idyllic sites in Mendocino County deliver incredible depth of flavor and character in the glass. Each vineyard, although heavily influenced by the Russian River, conveys its own topography and terroir. Each wine, in turn, reveals the nuances of a single site, through the lens of the winemaker.

Butler Ranch Vineyard

Perched at 2,200 feet in the Mendocino Range of California’s coastal mountains, Butler Ranch Vineyard is a remarkably rugged site teeming with native biodiversity. A former cherry orchard before grape vines were planted to its clay loam soils in 2001, Butler Ranch leaves more than 85% of its land untouched, allowing deer, foxes, bears and other wildlife to flourish alongside the organically farmed vines. The Rhône varieties here are planted as far west as they can be ripened in Mendocino County, making The Butler–the site’s signature Syrah-based blend–quite unique.

McNab Ranch Vineyard

A century after its origins as a sheep farm, McNab Ranch Vineyard captured the imagination of organic viticulture icon, Jim Fetzer. Drawing on the knowledge of legendary biodynamic farming expert, Alan York, Fetzer transformed the site into a model of sustainable winegrowing in 1996. Today, McNab Ranch is a beacon of regenerative organic viticulture, an idyllic site where sheep graze on cover crops to reduce tractor passes and beneficial insects naturally ward off unwanted pests. The vineyard’s moderate microclimate fosters a fresher, more youthful style of Cabernet Sauvignon than its Napa Valley counterparts.

Blue Heron Ranch Vineyard

Blue Heron Vineyard is aptly named for the great Blue Herons that nest in the oak trees along the Russian River, hovering above Bonterra’s signature site for white grape varieties. Alongside these stately birds, organically farmed vines bask in months of sunshine, delivering an exquisitely aromatic Chardonnay.
