TL;DR: Grace Benoist Ranch is Etude's 1,500-acre estate vineyard in the Carneros AVA in Sonoma Valley. Only one-third of the ranch is planted to vines. The remaining two-thirds are preserved in their natural state to protect native trees, waterways, wildlife corridors, and ecosystems. Sustainability practices include no tree removal, 12 miles of maintained wildlife corridors, riparian setbacks along Champlin Creek, sheep grazing for natural cover crop management, and precision irrigation using a pressure chamber system.
Stewardship as a Philosophy
At Etude, we are winemakers. We are also farmers, and farmers understand something that is easy to forget in a production context: the land does not belong to us. We belong to it.
Grace Benoist Ranch, our 1,500-acre estate in the far northwest corner of the Carneros Appellation in Sonoma Valley, is managed from that starting point. The decision to plant only one-third of the available acreage to vines was deliberate. The rest is left in its natural state, because the health of the unplanted land directly supports the health of what grows in the planted land.
Sustainable farming is not a constraint on wine quality at Etude. It is the foundation of it.

Rather than planting in a traditional grid to maximize vine density, the estate vineyard at Grace Benoist Ranch is configured into dozens of small, individually managed sites averaging approximately eight acres each. This approach allows the farming team to treat each block according to its unique soil type, aspect, and microclimate rather than applying blanket practices across the entire estate. It also leaves room for the land to breathe.
No Tree Removal
Native California oak and bay laurel trees grow across the ranch, including one remarkable oak with a trunk measuring 56 feet in circumference. No trees are removed to accommodate vineyard plantings. Where vines and trees coexist, the trees stay.
This is not a sentimental decision. Native trees provide habitat, regulate local temperature through transpiration, support biodiversity, and contribute to the soil ecosystem that feeds the vines around them. They are working parts of the farm.
12 Miles of Wildlife Corridors
Etude maintains 12 miles of wildlife corridors across the Grace Benoist Ranch estate. Vineyard blocks are fenced separately to protect open spaces, preserve wildlife habitat, and allow for the natural migration patterns of the animals that share the ranch.
Barn owls, wild turkeys, deer, woodpeckers, bobcats, mountain lions, and numerous other species move through the property regularly. Their presence is not incidental. Barn owls and raptors manage rodent populations without chemical intervention. Beneficial insects including ladybugs and lacewings control aphids and spider mites naturally. A healthy, diverse wildlife population is part of how the farm functions.
Riparian Setbacks and Champlin Creek
Champlin Creek runs through the south end of the vineyard. For much of the year it is a dry corridor bordered by trees. During the rainy season, it flows and becomes one of the most ecologically important features of the property.
By maintaining significant riparian setbacks, keeping vineyard plantings, roads, and structures well back from the creek's banks, Etude allows natural wetlands to form around the waterway each winter. These wetlands reduce erosion, provide habitat for birds and wildlife, slow water movement across the landscape, and allow water to filter into the soil and replenish the aquifer below.
Etude is actively working to restore and protect Champlin Creek in collaboration with neighboring landowners as part of the Fish Friendly Farming certification program.
Sheep Grazing for Natural Cover Crop Management
To keep tractors out of the vineyard as much as possible and prevent soil compaction when the ground is wet, sheep are brought in to graze between vine rows in the spring. The approach delivers multiple benefits simultaneously.
Sheep hooves trodding the soft spring soil help rain percolate into the ground rather than running off the surface. The grazing manages weeds and cover crops without machinery. And the sheep fertilize the soil naturally as they move through, returning nutrients to the ground that support the vine roots below.
It is low-technology farming working at its best.
Precision Irrigation: The Pressure Chamber
While underground well water is available for irrigation on site, Etude uses it as sparingly as possible. A key tool in that effort is the pressure chamber, a portable device that measures vine water stress by testing how much moisture a leaf releases under pressurized air.
By testing vines in different blocks throughout the growing season and combining those readings with soil moisture data, the vineyard team can calibrate drip irrigation at a granular level, applying water only where it is needed, only when it is needed, and only in the quantity required. The goal is the minimum effective input: enough water to keep the vines healthy, no more.
A degree of water stress in wine grapes is beneficial. It encourages deeper root growth, keeps canopy in check, and produces smaller berries with more concentrated flavor and aroma. The pressure chamber helps the team find and hold that balance.
FAQs: Grace Benoist Ranch and Vineyard Sustainability
How large is Grace Benoist Ranch?
The ranch totals 1,500 acres. Approximately one-third is planted to vines. The remaining two-thirds is preserved in its natural state to protect native trees, waterways, wildlife corridors, and ecosystems.
Why does Etude only plant one-third of Grace Benoist Ranch?
Leaving two-thirds of the ranch in its natural state is a deliberate sustainability decision. The health of the unplanted land, its trees, waterways, wildlife, and soil biology, directly supports the health and quality of the planted vineyard. Etude's belief is that sustainable farming and wine quality are not competing priorities. They reinforce each other.
What wildlife lives at Grace Benoist Ranch?
Barn owls, wild turkeys, deer, woodpeckers, bobcats, mountain lions, and numerous bird species are regularly observed on the property. Beneficial insects including ladybugs and lacewings are an active part of the farm's natural pest management program.
What is a riparian setback?
A riparian setback is a buffer zone that keeps agricultural development away from a waterway's banks. At Grace Benoist Ranch, setbacks along Champlin Creek allow natural wetlands to form during the rainy season, reducing erosion, supporting wildlife habitat, and allowing water to recharge the aquifer.
What certifications does Grace Benoist Ranch hold?
The ranch and winery collectively hold four certifications: Certified California Sustainable Winegrowing (CCSW), Napa Green Winery, Fish Friendly Farming, and Climate Adaptation Certification. Learn more at etudewines.com/pages/sustainability.
How does sheep grazing benefit the vineyard?
Sheep graze between vine rows in the spring, managing weeds and cover crops without machinery, reducing soil compaction, helping rainwater percolate into the soil, and fertilizing naturally as they move through the vineyard.
