In this episode of Grown in Napa Valley, NVG celebrates its 50th Anniversary by honoring two influential figures who shaped—and continue to shape—Napa Valley’s viticultural legacy. The episode begins with a rich conversation with Andy Beckstoffer, one of NVG’s founders, who shares the story behind the organization's creation and the pivotal moments that helped elevate grape growers from second-class status to key decision-makers in the wine industry. From advocating for the 75% appellation rule to establishing vineyard-designate branding, Beckstoffer reflects on the early battles for grower respect, the transition from commodity farming to quality-driven practices, and how the region found confidence in its own identity following the 1976 Judgment of Paris.

Then, we share a glass with the 2025 Grower of the Year Oscar Renteria, who reflects on his upbringing in a multi-generational farmworker family and his journey toward leading Renteria Vineyard Management. Oscar speaks with heartfelt optimism about resilience, legacy, and mentorship, emphasizing the importance of education, cultural pride, and finding joy in hard work. His leadership style—rooted in gratitude, empathy, and teamwork—embodies NVG’s mission and offers a forward-looking perspective for the next generation of Napa growers navigating uncertain times with hope and purpose.

• “The background of the formation of the Grape Growers was respect. We wanted respect as growers—and that changed everything.” – Andy Beckstoffer
• “The vineyard brand can be more valuable than the winery brand—if you market your vineyard, not just sell your grapes.” – Andy Beckstoffer
• “I came back to Napa not because I had to—but because I saw the beauty, the legacy, and the chance to build something meaningful with my father.” – Oscar Renteria
• “I find the most fulfillment in mentoring others—helping people grow is how I measure success today.” – Oscar Renteria
• “The mantra is ‘wine is grown in the vineyard’—but for too long, the value wasn’t passed through to the grower. That changed here in Napa.” – Caleb Mosley
• “We're celebrating 50 years of grit, collaboration, and excellence—and the people who made Napa Valley what it is today.” – Caleb Mosley

In this episode of Grown in Napa Valley, Executive Director and host Caleb Mosley celebrates the Napa Valley Grapegrowers' 50th anniversary with two in-depth conversations highlighting the region's rich history, agricultural legacy, and future challenges.
​
The episode begins with Richard Mendelson, a renowned wine lawyer, author, and historian. Richard discusses the pivotal moments that shaped Napa Valley, from the 19th-century wine pioneers to the post-Prohibition revival and the creation of the Agricultural Preserve in 1968. He emphasizes the critical role of human influence in terroir, the importance of resilience in the face of climate change, and the need to preserve Napa’s agricultural heritage. 

The conversation continues with Ren Harris, one of the founding members of the Napa Valley Grapegrowers and a celebrated vintner. Ren reflects on his early days in Napa, the region’s shift from prunes to vineyards, and his instrumental role in creating the Napa Valley Grapegrowers organization.

Ren also discusses the evolution of vineyard practices, his family’s Paradigm Winery, and the significance of preserving Napa’s community spirit and agricultural lands amid climate and economic changes.

This episode is brought to you by Pulido Walker Estate Vineyards. 

"The secret to Napa Valley's success is people, not just terroir. Terroir includes the natural elements, but it also includes the human element — the people who plant the vineyards, work the fields, make the wine. Without that, it's not a complete picture." – Richard Mendelson

"The Agricultural Preserve was a bet on Napa’s future before anyone knew what was coming. It was about preserving the land for agriculture at a time when many didn’t believe in the potential of wine here. It remains the most important decision in Napa's history." – Richard Mendelson

"Social justice is now a part of terroir. When I traveled the world to protect the Napa Valley name, people asked me how we treat our farmworkers. It’s become clear that how we care for our community is just as important as the land itself in defining our identity." – Richard Mendelson
​
"You make your wine in the vineyard. I always tell Heidi Barrett, 'We're bringing you really good grapes — just don’t screw it up!' It’s all about even ripening and meticulous farming, and you can’t achieve that by cutting corners." – Ren Harris

"Two dirt farmers from Napa got the federal government to change appellation laws for the entire country. We used the tools we had — connections, common sense, and persistence — to ensure that if it says Napa Valley on a bottle, it means something." – Ren Harris

In this episode of Grown in Napa Valley, Executive Director and host Caleb Mosley engages in two thought-provoking conversations that explore the present and future of Napa Valley's wine industry.

Kicking off with Jon Moramarco, managing partner of BW166 and a renowned expert in beverage alcohol trends. Jon shares his journey in the wine industry, insights into seismic shifts in global wine markets, and the challenges facing Napa Valley. Jon highlights the importance of innovation, smarter business practices, and the potential for Napa to explore new opportunities to remain a leader in the global wine industry.
​
The episode continues with Paul Goldberg, 2024 Grower of the Year and vineyard manager at Bettinelli Vineyards. In this candid conversation, Paul reflects on his Napa upbringing, his journey into viticulture, and the evolution of vineyard practices over the past 50 years. Paul discusses the meticulous farming techniques Bettinelli employs to enhance phenolic development, the importance of adapting to changing market demands, and the opportunities to champion diverse grape varietals. He also shares the story of Sleeping Lady Vineyard and the 2019 Ad Vivum Cabernet Sauvignon he brought.

"Napa is an anomaly. The rest of the country doesn’t live like we do here, and understanding that reality is key to shaping the future of the wine industry." - ​Jon Moramarco

"What was three or four passes through a vineyard in the 1970s has now grown into 10, 11, sometimes 12 passes—each one critical to achieving balance and quality." - Paul Goldberg

"The global wine market has been oversupplied for 20 years. For Napa to thrive, it’s about being smarter, innovating, and working harder to stand out." - Jon Moramarco

"When you actually walk a row with someone and explain how a vineyard is planted, trellised, and managed, it creates a level of appreciation that’s mind-blowing." - Paul Goldberg

"If I can enjoy life with my wine every day, and it shortens my life by two months, I’d say that’s worth it." - Jon Moramarco

In this episode of Grown in Napa Valley, host Caleb Mosley takes listeners on a journey through two critical aspects of Napa Valley’s wine industry: climate change and grower relations. First, Caleb sits down with Andrew Isaacs, a professor at UC Berkeley’s Haas School of Business and climate expert, to discuss the evolving challenges that climate change presents for grape growers. They explore how climate impacts viticulture, and the importance of both mitigation and adaptation strategies in the vineyard. Andrew partnered with NVG on a six-part Climate Science video series to provide on-demand education for the industry.
​
Then, for our Glass with a Grower segment, Caleb sat down with Jan Kappmeyer, a seasoned grower relations expert with 15 years of experience at Constellation Brands. Jan shares her career journey and the unique challenges she faced while navigating the dynamic relationships between growers and wineries. She offers valuable advice on how growers can approach contracts, manage market downturns, and maintain strong relationships with winemakers. Jan also introduces a special Viognier that she and her husband produce, sharing the story behind the vineyard and the wine itself. 

"Climate is just long-term weather. So day to day, we call it weather, but decade to decade, we call that same thing climate. And that’s what’s changing. For farmers, it’s right in front of our faces." - Andrew Isaacs

"Reducing emissions on a vineyard isn’t just about what happens within the four corners of your property—it’s a holistic lifestyle shift. It’s not just fewer tractor passes; it’s rethinking everything we do." - Andrew Isaacs

“Every single time there’s a downturn in a particular industry, the climate footprint of that industry goes down too. The reason is people cut costs—anything discretionary ends up on the cutting room floor.” - Andrew Isaacs

"In grower relations, you have to be honest and share your opinions—whether it's for one side or the other. That transparency and curiosity are what makes it work." - Jan Kappmeyer

"It’s like having a foot in two different canoes—you’re balancing the needs of growers and winemakers. Sometimes it goes one way, sometimes the other, but it’s all about keeping those relationships strong." - Jan Kappmeyer

​Harvest season is winding down in Napa Valley, and it's time to look ahead! In this episode of Grown in Napa Valley, our host, Caleb Mosley, Executive Director of the Napa Valley Grapegrowers, sits down with Tom Johnson from Kamprath Seed to explore how growers are preparing for next season with cover crops and soil health.
​
Next, in our "Glass with a Grower" segment, we share a bottle of 2022 Matthiasson Refosco with the legendary Steve Matthiasson. Listen in as Steve reveals his unique approach to viticulture and how this vintage embodies the diverse terroir of Napa. It's an episode full of insights, tips, and of course, a little wine talk—cheers!

"Cover crops can do so much more than just prevent erosion; they bring life back into the soil, retain moisture, and even attract beneficial insects. It’s about creating a system that supports the vineyard in ways that go beyond what we see on the surface." - Tom Johnson

"Our job as viticulturalists is to support them and give them the tools and set them up for success...these vines are on our team...it’s a team effort." - Steve Matthiasson

"There isn’t a single example of a sustainability practice that doesn’t also enhance wine quality...cover cropping is a tool that builds wine quality." - Steve Matthiasson

"We used to grow a lot more different varieties of grapes in Napa...and I think for the long-term health of us as a wine region, where a wine lover can spend their life exploring deeper and deeper, we need to have more diversity." ​- Steve Matthiasson

In this special episode we take you out into the field to explore two impactful programs: the Patrick Foley Fields of Opportunity Summer Mentorship Program and NVG’s Paso Adelante committee.

First, we attend the Fields of Opportunity graduation, where 30 students completed an intensive 8-week summer mentorship. We heard firsthand from  students, their mentors, and special guests. Then, Cris Romero, a founding member of Paso Adelante, shares how this new initiative is paving the way for young professionals in viticulture and winemaking.

Tune in to discover how these programs are shaping the future of our wine industry and creating opportunities for the next generation of leaders right here in Napa Valley.

"Our hope was that we could connect local high school students with a career opportunity in their backyard, in the wine industry. It began as a two-week program and has evolved into a full summer mentorship that really has fostered or helped us foster the next generation of industry leaders." - Sonya DeLuca

"I absolutely see the Paso Adelante committee or people impacting the industry. It’s really a space for the next generation of decision makers to come together and meet and kind of form that network... a passing of the baton, a bridging of the gap between this young generation and the older one that's already established." - Cris Romero

"Because as we know in the Valley, we're all connected. Whether it is from picking the grapes, to processing them, to bottling it, to selling it, we're all one. You're part of something bigger here." - ​Myra Ayala
