    Episode 20: 2025 Harvest Highlights: Quality Through Adaptation

    In this episode of Grown in Napa Valley, guest host Jonathan Cristaldi presents highlights from the 2025 Napa Valley Harvest Press Conference, presented by the Napa Valley Grapegrowers and Napa Valley Vintners,  joined by growers and winemakers Ashton Leutner, Mayan Koschitzky, Nate Weis, and Megan Gunderson. They unpack a cooler, steady 2025 growing season shaped by early rains, slow canopy development, minimal heat spikes, and strong fruit set. With phenolic ripeness outpacing sugar accumulation, the panel notes vibrant color, natural acidity, and balanced alcohol across the vintage. They discuss the year’s key challenges — elevated mildew pressure and a stop-and-start harvest caused by intermittent rain — and share how tight spray intervals, sport-trap monitoring, and thoughtful canopy work helped maintain fruit quality. Market shifts also left some fruit unharvested, creating an opening for growers to redevelop vineyards, adjust crop loads, and focus on long-term soil and plant health. The conversation turns to the Pickett Fire, which produced highly localized smoke impacts. Thanks to improved air-quality tools and advanced ETS smoke-taint testing, growers were able to assess risk with far more precision than in past fire years. Early takeaways from the panel point to a distinctive, expressive 2025 vintage — wines with strong color, refined tannins, and clear AVA character — underscoring a maturing Napa Valley rooted in adaptation, stewardship, and continuous learning.

    Trellis Talks: From Caldera to Cabernet: The Ancient Lake Beneath Coombsville

    In this episode of Trellis Talks, Caleb Mosley sits down with soil scientists Dr. Paul Anamosa and Dr. Nick Madden to explore their 2023 paper, “The Other White Rock in Coombsville Vineyards.” The conversation unpacks the geological mystery and viticultural significance of diatomaceous earth found in the Coombsville AVA—a lightweight, silica-rich sediment formed from freshwater algae in an ancient caldera lake. Anamosa and Madden discuss how these unique soils, often mistaken for volcanic ash or bentonite, impact vine growth, emphasizing their low pH, high aluminum toxicity, and unusual water retention characteristics. They explain how proper soil analysis and management—particularly the use of gypsum and lime—are crucial for successful vine development in these challenging conditions. The episode also delves into the broader story behind their collaboration, from international development work to building one of Napa’s most extensive soil pit databases. As Paul transitions into retirement, he reflects on the importance of mentorship and passing on deep technical knowledge to the next generation of consultants like Nick and their colleague Scott Nippelmeyer. Their combined efforts promise a new era of viticulture grounded in science, innovation, and deep respect for Napa Valley’s complex terroir. Support the show

    Episode 19: Fighting Fire with Foresight: Lessons from the Pickett Fire with CALFIRE Chiefs Matt Ryan and JC Greenberg & Glass with a Grower, Bill Hanna

    In this episode of Grown in Napa Valley, host Caleb Mosley speaks with CAL FIRE’s Matt Ryan and JC Greenberg about the recent Pickett Fire in Calistoga and the evolution of wildfire management in Napa County. They recount how lessons learned from past disasters like the Glass Fire informed a faster, more coordinated response, aided by years of fuel reduction, maintained containment lines, and collaboration with Napa Firewise. New technology—including AI-enabled smoke detection, night-flying helicopters, and mobile retardant bases—has revolutionized early fire response. The chiefs emphasize that resilience depends on community-wide preparedness: defensible space, pre-fire planning, and responsible vineyard burn practices to prevent smoke impacts during harvest. The conversation then turns to Bill Hanna, Napa Valley Grapegrowers’ first Lifetime Achievement Award recipient, who reflects on his family’s 50-year partnership with Château Montelena and their deep roots in Napa farming. Hanna shares how trust, quality, and collaboration have sustained this grower–winery relationship across generations. Beyond the vineyard, he highlights decades of advocacy for farmworker housing and community well-being, noting Napa’s leadership as the only county where growers self-assess to fund workforce housing. Looking ahead, Hanna discusses the need for balance—between groundwater use, vineyard density, pricing, and long-term environmental stewardship—underscoring education and cooperation as the keys to Napa Valley’s enduring agricultural legacy.

    Episode 18: Innovation Without Borders: Grapegrowing in a Changing World with Julien Dumercq & Glass with a Grower, Randy Heinzen & Donnell Brown

    In this episode of Grown in Napa Valley, host Caleb Mosley first speaks with Julien Dumercq of IVES (International Viticulture and Enology Society), who highlights the organization’s mission to provide open-access research in viticulture and enology. Julien explains how IVES grew from a small initiative in Bordeaux into a global network of 35 universities and research institutes, supported by members and partners including several Napa Valley wineries. Their peer-reviewed journals, multilingual technical reviews, and international conferences foster collaboration and innovation, ensuring that research is widely available and free from financial barriers. Julien emphasizes the importance of building community across continents, sharing best practices, and maintaining scientific integrity while adapting to new technologies like AI. The conversation then turns to the U.S. with Randy Heinzen of Vineyard Professional Services and Donnell Brown of the National Grape Research Alliance (NGRA). Randy shares his journey from Napa to Paso Robles and his experiences farming across diverse sites, underscoring the value of research and cost-based vineyard management. Donnell explains NGRA’s national role in setting research priorities for all grape sectors—wine, juice, table, and raisins—and in advocating for projects with USDA and funding agencies. Together, they stress the importance of collaboration, sustained investment in research, and engaging the next generation of leaders to address challenges such as climate change, pests, and shifting market dynamics. The episode highlights Napa Valley’s role in both global and national research efforts, bridging science and practice to support resilient grape growing. Support the show

    Episode 16: Economics of the Wine Industry: From Data to Dirt with Dr. Chris Bitter & Glass with a Grower, Mike Wolf

    In this episode of Grown in Napa Valley, NVG tackles the economic headwinds facing the wine industry through an in-depth conversation with wine economist Dr. Chris Bitter of Terrain. Bitter breaks down the latest insights from Winescape, Terrain’s quarterly market report, revealing a shift in U.S. alcohol consumption trends. He explains how demographic changes, evolving health attitudes, and a rise in cannabis and GLP-1 drug usage are contributing to a measurable decline in per capita alcohol use—particularly among younger consumers. While all beverage categories are impacted, Bitter notes that wine is facing steeper challenges, with premium pricing and oversupply adding to the pressure. Still, he emphasizes Napa Valley’s long-term strength, citing its reputation for quality as a key advantage in weathering this downturn. Later in the episode, Caleb shares a glass of 2016 Heimark Vineyard Napa Valley Cabernet Sauvignon with veteran vineyard manager Mike Wolf, in a conversation that spans mentorship, humility, and the philosophy of farming. From early lessons learned under the guidance of instinctive farmers in Mendocino to decades spent managing top-tier vineyards in Napa, Wolf reflects on the value of hands-on experience and the importance of staying true to the land. He speaks candidly about the tension between aesthetics and economics, and the quiet pride that comes from getting the work done right—often before anyone notices. Through stories of resilience, collaboration, and a commitment to the next generation of farmworkers, Wolf embodies the spirit of Napa Valley viticulture: rooted in history, shaped by community, and always looking ahead.
