Our Story

OLD WORLD WINES IN SAN DIEGO

The first vineyards in California were planted right here in San Diego at the Mission San Diego de Alcalá. Our hope is to establish San Diego County as a well known wine region, bringing wine lovers from all over the world to experience the taste and beauty of our area.

Twin Oaks Valley Winery is a family owned and operated business. Established in 2001, the winery was purchased by Malcolm and Kathryn Gray in 2013 to introduce new and updated winemaking techniques to making old world wines and refresh the brand. We specialize in crafting small batches of wine from the finest grapes grown in San Diego County. We are proud to support our local farmers and growers.

“MY GOAL IS TO BRING THE GRAPE CHARACTER IN ITS PUREST FORM, AN EXPRESSION OF TERROIR."

The Winemaker

MALCOLM GRAY

As a member of the San Diego County Vintners Association, we collaborate with other wineries in the region to support the growth of winemaking and viticulture in Southern California, specifically the San Diego region. Malcolm’s passion for winemaking started with his passion for drinking wine. As an accomplished Electrical Engineer working in Silicon Valley for over 25 years, he would spend weekends at wineries in the Santa Cruz Mountains and the Sierra Foothills that led to extensive, in-depth conversations with the winemakers about grape varieties, climate and soil.  Malcolm began reading everything he could get his hands on about grapes, grape growing regions and the art of making wine.  He then attended enology courses at UC Davis when he realized, “this is what I really want to do”

Malcolm absorbed himself in “everything about wine making”, expanding his knowledge and developing his skills. His efforts paid off, winning a silver medal for the inaugural red blend, 2013 Sunset Red, at the 2016 San Diego Wine and Spirits Challenge.

Our Future

WATCH US GROW

As the winery has grown over the years so has the desire to create new wine experiences for our visitors. Twin Oaks Valley Winery strives to educate guests about wine, wine making and their tasting experience.

 

The next chapter in the Twin Oaks Valley Winery story will be the construction of a new winery next to our current location. It will include a production facility, tasting room with underground expansion, and a dedicated outdoor space for live music and special events.

 

Our new facility will be situated overlooking the Twin Oaks Valley and will give guests the opportunity to stroll through our Estate Syrah vineyard, sipping on a glass of their favorite Twin Oaks Valley Winery vintage.

 

Stay tuned for the progress. We hope you will join us on this journey.
