In recent years, there is not only consumer demand for knowing how your food is farmed, but the health of farmworkers and neighbors to farms is also something that demands transparency. For many SLO Coast vineyards, the decision to farm and produce wines using sustainable, organic, and biodynamic practices is part of their brand’s DNA and for others, it is a practice they adopted in recent years to ensure healthy vines and wines for years to come. 

Not all wine is created equal, nor are all grapes grown equally in the vineyard. Many wineries throughout the San Luis Obispo Coast farm their vineyards and make their wines “sustainably,” meaning they choose to save water, encourage biodiversity, take care of their workers and give tasters wines that do no harm to Mother Earth.

Sustainable Vineyards and Wineries on the SLO Coast

Sustainability addresses the 3 P’s – People, Planet, Prosperity – ensuring that both natural and human resources are protected. Holistic practices address habitat, water, energy, soil, recycling, air quality, packaging, pest management, social equity, and business management. Sustainability certification is determined by third party organizations (e.g. SIP Certified) and certified vineyards and wineries must adhere to a rigorous set of standards that are verified by a third-party inspector. 

1. Baileyana Winery (SIP Certified)

Baileyana, Tangent & True Myth Wines in SLO Coast Wine country

Back in 1909 local farm workers in Edna Valley constructed the Independence Schoolhouse in what was then empty farmland. Today that land is rich with wine grapes stretching as far as the eye can see. Baileyana wines can be sampled in that same schoolhouse; a bright, airy place with idyllic views of vineyards. This  winery grows over 10 different grape varieties in their SIP Certified Paragon Vineyard. The SIP Certified seal indicates the commitment on behalf of the team to preserving and protecting the natural environment, treating employees and community with care, and sound business practices with a long-term outlook. At the Schoolhouse you’ll find over 25 SIP Certified sustainable wines, including Chardonnay, Pinot Noir, Syrah and Sauvignon Blanc.

3. Chamisal Vineyards (SIP Certified, working towards Demeter Biodynamic certification)

Chamisal Winery on the SLO Coast

Chamisal Vineyards has been SIP (Sustainability in Practice) certified in the vineyards since 2010 and we were the the second-ever winery to be SIP-certified in 2016, though the winery has always gone above and beyond the requirements to maintain the health of our vineyards and improve biodiversity in the area.

To achieve SIP Certified for a winery, the company must undergo an in-depth assessment of their entire facility operations. This includes a rigorous evaluation of a variety of items including (but not limited to) facility establishment and management, energy uses, water efficiency, purchasing, recycling and waste reduction, marketing materials, event needs, and landscape decisions. All elements of social equity and financial sustainability are also taken into account, as with the current vineyard certification program.

In 2020, Chamisal began a shift towards biodynamic practices and have introduced numerous regenerative agricultural measures including the installation of a Miyawaki forest and community vegetable garden that is farmed on behalf of the San Luis Obispo Food Bank.

In the vineyard, they foster a healthy population of birds and owls for natural predation of unwanted pests, they have eliminated the use of herbicides, utilize cover crops to increase biodiversity, and irrigate with recaptured winery processed water. They generate 25% of our electrical power from solar panels and have an extensive system of moisture probes and sensors to reduce our water usage in the vineyard.

4. Claiborne & Churchill (SIP Certified)

Claiborne & Churchill Winery in Edna Valley, San Luis Obispo Coast

Claiborne & Churchill is a small, premium family-owned winery in the Edna Valley of San Luis Obispo, founded in 1983 by Claiborne (Clay) Thompson and Fredericka Churchill Thompson.

6. Talley Vineyards (SIP Certified)

Sustainable Wine from Talley Vineyards in SLO Coast Wine region

We Got Your Fruits and Vegetables – Brian Talley, Grapegrower
The Talley Family has been growing vegetables in the Arroyo Grande Valley since 1948. In 1982 they planted a test plot of grapes on the west hillside of what is now their Rincon Vineyard. A successful first vintage convinced them to plant additional acreage in both the Arroyo Grande Valley and Edna Valley. The Talleys now farm more than 150 acres of SIP Certified vineyards along the cool, hilly coastline of San Luis Obispo County. Today the winery is owned and operated by Brian Talley and his wife Johnine. Their hard work has helped establish the San Luis Obispo Coast region as one of the leading places in California for Chardonnay and Pinot Noir, including sustainable wine.

“More than 30 years ago we began a tradition of delivering produce from our farm to our best winery customers. I love the look on people’s faces when I show up with a box of peppers and avocados instead of a case of Chardonnay or Pinot Noir.”

7. Timbre Winery (SIP Certified)

Sustainable Wine Trail on the SLO Coast in San Luis Obispo Wine Country

For Joshua Klapper of Timbre Winery, the decision to source fruit from certified sustainable vineyards was one that was forward thinking, “As a business centered in agriculture, and parents to young children, we felt it was important to support efforts in sustainably so that we are leaving to our children the best world we can.” 

Timbre approaches their whole business from a sustainable perspective and Klapper adds, “We have tried to cut down on waste by doing many small things. We stopped using imported foil capsules on our wine bottles long ago as they served no real purpose except waste. Additionally, for local consumers, we have created a growler program so that people can buy some of our wines in reusable containers.”

It’s really about a collective community for Klapper and he points out that, “I have found that the most interesting and passionate people in the wine business today are proponents of sustainable farming and winemaking. I am proud to be part of a region that holds sustainability in such high regard. A good friend and vineyard manager told me that his focus on sustainability has helped him become a more efficient and better farmer, and I would agree with that assessment based on the countless sustainable vineyards we source at Timbre.”

9. Wolff Vineyards (SIP Certified)

Wolff Wines at Harvest on the Coast - Sunday Winery Open House

Wolff Vineyards was established 44 years ago by one of the first wine grape-growing pioneers in the Edna Valley. The winery’s focus is on Riesling, Chardonnay, Pinot Noir, Syrah, Petite Sirah and a rare Italian red variety called Teroldego. The wine tasting facilities include a tasting room, including sustainable wines, and outdoor flower garden suitable for picnics. The tasting room is situated on top of a hill providing unique panoramic views of the Edna Valley. Some of Wolff’s first viticultural experiments involved moving away from conventional farming to more ecologically sustainable practices. The vineyards were one of the test sites for the SIP Certified program.

Today, Wolff regularly engage in trials and research projects with Cal Poly and various agricultural and environmental groups. “In how many appellations can you go to the beach, get sand between your toes, then within 15 minutes go wine tasting in a vineyard? You’re going to have a hard time finding that anywhere else,” says owner Jean-Pierre Wolff.

Biodynamic Farming on the SLO Coast

Biodynamic wine takes a more spiritual and cosmic approach to winemaking adhering to the philosophy that everything in the world is interconnected and the vineyard should be farmed as a single being with a closed system independent of imported materials. Demeter is the certifying body in biodynamic farming. Biodynamic farming follows the lunar calendar which dictates when to perform certain farming practices. No manufactured additives can be added to these wines, soils, etc. 

10. Sinor-LaVallee (in process of Demeter Biodynamic certification)

Sinor-LaVallee Biodynamic Prep 501 & Bees in Vineyard

Mike Sinor of Sinor-LaVallee Wines, his decision to employ biodynamic farming practices was inspired by a trip to Burgundy in 1996 where it was being experimented with at top domaines. Mike was intrigued by the process and was excited to learn more about it. He farms his Bassi Vineyard organically with biodynamic inputs because as he says, “These practices are observed, first and foremost, because they help make better wine. No stone is unturned in that pursuit. What is great for the wine is also good for the land and the surrounding environment, so the rewards are ample for keeping everything in balance.”

Explaining the practices of Biodynamic farming isn’t always the easiest conversation with consumers and Sinor says, “When people first hear about Biodynamics they get distracted by some of the seemingly strange practices (filling cow horns with cow excrement, burying them according to the moon/planets then spraying that material in homeopathic levels) In the end anyone who appreciates the Farmers Almanac and has an open mind will learn its not that strange.”

The SLO Coast Wines commitment to the environment and the overall wellbeing of its people and lasting effect on the world is evident in the passion that many of these winemakers and vintners have for the land. Applying the practices of sustainable agriculture, organic farming, and biodynamic methods create structure and provide a roadmap for farming for a better future. As our world continues to change and evolve, we can find comfort in the folks of SLO Coast Wines doing their part to respect and honor the land they farm and the wines they work with.

12. Biddle Ranch (farms sustainably)

Handcrafted in the heart of the Edna Valley, Biddle Ranch is a celebration of belonging to land where doing what fills the soul and lifts the spirit comes naturally. Not that long ago, friends with deep roots in California’s Central Coast planted the seeds to start making wine. What you see now is the labor of love that took these families on a journey into winemaking. Biddle Ranch has been SIP-certified since 2015.

Known for one of the longest ripening seasons in California, winemaker Ryan Deovlet fell in love with the land that holds Biddle Ranch for possessing all the essential conditions for creating balanced, old world style wines. Tending Biddle Ranch’s estate 17 acres of Chardonnay, and sourcing from Santa Ynez, to the Edna and Arroyo Grande Valleys, and up to Paso Robles, he personally hand selects fruit from only the best soil and growing climate for each of their limited-production wines, including their sustainable wine.
