As a 100% estate grown, sustainably farmed winery, St. Supéry has over 1,600 acres of land with two thirds left in its natural state encouraging biodiversity. From the very beginning, we have farmed and operated as stewards of the land with preservation is our top priority.
The Dollarhide property thrives with a diverse collection of flora and fauna including ducks, geese, cranes, egrets, jackrabbits, owls, bees, foxes, osprey, otters, bobcats and thousands of largemouth bass. Dollarhide is home to the majority of the vineyards and also to more than 1,200 heirloom fruit trees comprised of over 160 varieties; 87 peach, 34 nectarine, 20 apple, 12 plum and 16 Pluot. Bluebird and owl boxes can be found throughout their properties further encouraging a balanced ecosystem.
St. Supéry’s culinary garden has been flourishing for 10 years supporting the farm-to-table initiative. The fresh produce from the gardens and fruit from Dollarhide Ranch are incorporated into the food and wine pairings, as well as, available to neighbors and local restaurants.
Rutherford and Dollarhide vineyards are planted to cover crops between the vine rows, to harbor beneficial insects, compete with weeds, add essential nutrients to the soil and limit erosion. The leaf canopies are managed to host beneficials balancing the threat of pests. Integrated Pest Management is utilized throughout as an effective and environmentally sensitive approach to managing unwanted pests.
All organic solids from the winemaking process are composted back to the vineyard. Reduced and no till systems have increased, reducing emissions and preventing erosion. Additionally, St. Supéry’s carbon studies indicate both vineyard properties sequester +1400 metric tons/year.
The winery water usage has reduced by 50% in the last 5 years and all process water is recycled.
St. Supéry irrigates with captured rainfall and recycled water. The vineyard uses soil moisture probes to monitor soil moisture, as well as, pressure chamber readings to ensure sufficient water, without over watering.
Most recently, St. Supéry’s solar arrays offset 94% of the winery’s energy bill.
All winemaking, bottling and winery materials adhere to a strict purchasing policy.
Glass purchases are sourced in North America and include recycled glass.
Paper products average a minimum of 50% recyclable materials.
Within the immediate community and beyond, St. Supéry works to make a lasting difference and have deepened their community commitment.

With each bottle sold of the 2020 St. Supéry Napa Valley Estate Sauvignon Blanc, $5 was donated directly to the Napa Valley Community Disaster Relief Fund, committing to a contribution of more than $100,000. We recognize the need to replenish the fund as it continues offering community support.
Each November St. Supéry focuses on ways to give back to the community and educate its audience, whether that be through education, social equity, mental health or conservation, the winery looks to shine a spotlight on those in need and ways to help. We encourage you to donate to those causes close to your heart, or one of our favorite causes that we support here at St. Supéry.
