As he kicked off the Ahead of the Curve Conference, the Napa Valley Grapegrowers' executive director Executive Director Caleb Mosley did something that many of us have nightmares about.
Instead of reading his prepared remarks, Caleb Mosley pulled out and began reading his grocery list. But, a panicked Mosley was quickly assisted by the AI tool ChatGPT, which immediately responded to Mosley’s request for a “warm, professional welcome speech” with a series of paragraphs.
“While the world is buzzing with AI headlines and automation breakthroughs, we know that agriculture — our agriculture — is just beginning to test these tools in meaningful ways,” Mosley said...

Before there was a group called the Napa Valley Grapegrowers, there was a group of grape growers who were trying to ensure their livelihoods in the Napa Valley.
Friday evening, before the wine industry nonprofit gathered for a banquet to celebrate its 50th anniversary, two of its founding members reflected on a very different Napa Valley that gave rise to the Grapegrowers — a community in which farmers struggled to have their voices heard.
Ren Harris and Andy Beckstoffer — two of the 10 men who formed the Grapegrowers group in 1975 — met with reporters at the Foley Johnson Winery to look back at the wine world in which they and their industry came of age.

​Despite the rising fame of such local winemaking pioneers as Robert Mondavi, Mike Grgich and Warren Winiarski, grapes in the 1970s were but one farm product among many in the Napa Valley, often overshadowed by fruit and nut orchards, dairies and even Christmas tree farms. The modern-day web of hotels, resorts and fine restaurants that lures throngs of tourists to the Napa Valley was nonexistent.

Did you know a nearby eucalyptus tree can lend its minty essence to a glass of Cabernet? Or that babydoll sheep — as cuddly as their name suggests — can serve as a fluffy, four-legged alternative to chemical weed control in Napa Valley vineyards? Or that a single decision — from pruning to harvesting — can shape the taste of the wine in your glass?
These are just a few of the surprising facts shared with more than 100 curious locals Saturday afternoon as they wandered rows of budding grapevines during Afternoon in the Vineyards — a free, behind-the-scenes celebration of Napa County’s world-renowned wine culture.

Now in its 21st year, the annual event invites residents to step off the highway and into the heart of Wine Country, with tours and tastings hosted by Napa Valley Grapegrowers and Napa Valley Vintners, two nonprofits dedicated to preserving and promoting the region’s agricultural heritage.
This year’s tours led guests through four distinct properties: Bettinelli Vineyards, Firetree Family Vineyards, Chimney Rock Winery and Nickel & Nickel. Under clear blue skies, visitors hiked sun-warmed hillsides, breathed in the scent of wildflowers and sampled wines as winemakers shared the secrets behind each pour...

Ren Harris’ roots are firmly planted in California. He is a sixth-generation Californio, a descendant of José Carrillo, who came to the not-yet state with the Portolá expedition in 1769. Another ancestor was the sister-in-law of Sonoma’s founder, General Vallejo. The family of Harris’s wife, Marilyn, adds Napa Valley heritage, as the Pelissa family has farmed there for four generations. 

​In 1967, the couple purchased 30 acres of prunes in Oakville, which they sold in 1975 and acquired the 55-acre estate across the highway that is now part of Harris’s Paradigm Winery’s vineyards. It is also the source of its classic Napa Valley Cabernet Sauvignon wines.

​“The Agricultural Preserve saved Napa Valley,” says Harris. “My father-in-law, Andy Pelissa, was the only farmer on the Planning Commission when a zoning proposal was put forth in 1968 to stop chopping up farms into home sites. It passed to become the first agricultural preserve in the United States.“

​Half a century ago, a group of forward-thinking, passionate Napa Valley farmers met around Ren Harris' dining room table in Oakville to create the Napa Valley Grapegrowers. These pioneers recognized the unique potential inherent in this valley to grow grapes that could create wine worthy of competition with the finest offerings from across the globe. Over the past 50 years, NVG has evolved to address some of the most pressing issues facing the Napa grape-growing community, further establishing and protecting this amazing land for generations to come.
