We made history in 1973 as the first winery in Edna Valley to plant grapevines. Just 10 minutes from downtown San Luis Obispo, our tasting room offers sustainably produced wines painted with gorgeous natural scenery.


The People Behind the Wine

While some winemakers find their domain is limited mostly to the cellar, Fin is committed to spending just as much time in the Chamisal vineyards. Estate Director Andrea de Palo is dedicated to making sure that guests have a memorable experience at Chamisal.

As farmers and stewards of the land, we’re constantly striving to find its highest and best use.

Our unique soil types and proximity to the ocean have convinced us that it’s Chardonnay.

At Chamisal, we’re commited to growing truly world-class Chardonnay and showcasing each vineyard’s unique characteristics. 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.

Sustainable practices at Chamisal Vineyards include the use of compost, cover crops, minimal organic fertilizers, a rooftop solar array and the introduction of drought-tolerant rootstock and moisture-sensors to mitigate irrigation needs, as well as a water-recapture system that reclaims 100 percent of winery process water for irrigation needs.

Ron and Trish realized this could be the fulfillment of a dream…the storied Willamette Valley. In their view, the best Pinot Noir in the US. The opportunity was there for the taking. And they did.

The offer meant leaving the lifetime security of Lawrence Livermore National Laboratory where she ran the Computation Directorate of 1000 mathematicians and computer scientists to contemplate a move to Hillsboro, Oregon.

Ron was frequently reminded by Trish who said throughout the process that “see…if you keep the dream in sight…keep it alive…eventually it will happen.”
