In this episode of Grown in Napa Valley, host Caleb Mosley sits down with Dr. Monica Cooper and Dr. Malcolm Hobbs of the UC Cooperative Extension Napa County office for a wide-ranging conversation about how science gets translated into action in the vineyard. Monica, who has served as Napa's viticulture advisor since 2009, traces her research path from biocontrol and insect vectors of leafroll disease through to red blotch, which has become one of her primary focuses. Malcolm, who got his start counting ants in the vineyard part time, brings a social science lens to a field that doesn't always think in those terms. Together, they unpack a deceptively hard problem: how do you get neighboring growers to coordinate on a disease like red blotch, when that means having a sensitive conversation with someone you may have never met, or may have had a disagreement with in the past?

That question led Monica and Malcolm to study communication networks across the county and to explore the concept of neighborhood groups, voluntary, small-scale organizations where growers in close proximity can build the trust needed to actually work together on regional disease management. They talk through what makes those groups work, what gets in the way, and why spreading a new farming practice through a community looks a lot like any other kind of social change.

For Glass with a Grower, Scott Becker of Realm Cellars arrives with two bottles that tell fifty years of Napa history in a single sitting: the newly released 2024 Moon Racer from the Stags Leap District, and a 1974 Cakebread Cellars Cabernet, the winery's first-ever Cabernet bottling, sourced from the same district and pulled from a Silicon Valley cellar where it had been stored impeccably for decades. The conversation moves fluidly between the wines, touching on mentorship, the pioneering names of Napa's early era, and Realm's philosophy of stewarding vineyard legacies — keeping the names, the histories, and the intention of the people who came before.

In this episode of Grown in Napa Valley, host Caleb Mosley sits down with Tracy Cleveland, Napa County's Agricultural Commissioner and Sealer of Weights and Measures, for a candid conversation about one of the more alarming pest events in recent memory. What began as a routine call from a neighboring county inspector turned into an urgent, coordinated response after glassy-winged sharpshooter was discovered on grapevine shipments sold through Costco stores across Northern California. Tracy walks Caleb through the timeline, which stretched across four separate shipments arriving from late April through late May, and describes what it looks like on the ground when inspectors mobilize to track down where infested plants may have landed. She also offers a practical reminder for growers: with harvest approaching, now is the time to contact the Agricultural Commissioner's office and schedule scale inspections before the season gets underway.

The conversation goes deeper than the incident itself, touching on Tracy's 23 years with the county, her early days as a seasonal glassy-winged sharpshooter inspector, and the protocols her team uses when evaluating incoming plant material. She reflects on how the European grapevine moth eradication shaped the county's approach to pest response and emphasizes that keeping up this kind of vigilance requires community participation, from reporting suspicious plants to being thoughtful about moving material between regions.

For Glass with a Grower, Caleb welcomes Jason Haas, second generation proprietor of Tablas Creek Vineyard in Paso Robles, fresh off his appearance at NVG's Organic Wine Growing Conference. Jason traces the story of Tablas Creek from its 1989 founding, a partnership between his father Robert Haas and the Perrin family of Château de Beaucastel, through its evolution into the first winery in the world to earn Regenerative Organic Certification. He unpacks each of the certification's three pillars and shares why the social welfare component turned out to be the most transformative, leading to changes in how the vineyard team communicates, shares knowledge, and takes ownership of the work. Despite a challenging wine market, Jason closes on an optimistic note: the tools to build a resilient, forward-looking operation are there for growers and producers willing to look for them.

In this episode of Grown in Napa Valley, host Caleb Mosley welcomes Galen Becker Drace, Executive Director of the Napa Valley Hospitality Forum, to talk about what really happens on the tasting room floor. Drace discusses the difference between service and hospitality, the most common (and most memorable) questions guests ask, and how growers can help frontline staff speak confidently about soil, farming practices, and vineyard stewardship when it fits the moment. 

He notes that viticulture isn't always the right topic, given how much frontline staff are already reading and juggling with each guest in a short window of time, from wine club details to restaurant recommendations to simply sensing what a guest wants out of the visit. The conversation closes with an invitation for listeners to share the most memorable tasting room questions they've overheard or what they want to know.

In this episode of Grown in Napa Valley, Executive Director Caleb Mosley sits down with climate scientist Daniel Swain to discuss the unusual 2026 growing season and what Napa Valley growers should be paying attention to. Swain explains the record-breaking heat experienced in March and April, the complex relationship between climate change and extreme weather events, and why growers are increasingly dealing with both ends of the spectrum: severe drought conditions and periods of excessive rainfall. The conversation also explores topics such as offshore winds, fog, vapor pressure deficit, wildfire risk, and how a warming climate is changing the challenges facing agriculture across California. 

The discussion then turns to the developing El Niño, which Swain believes is highly likely to strengthen through the summer and could become one of the more significant El Niño events on record. He outlines the potential implications for California, including an increased likelihood of a wet winter, possible early-season rainfall events, and greater weather variability throughout the remainder of the year. Swain emphasizes that while climate change presents real risks, it also creates opportunities for California agriculture to rethink water management through groundwater recharge, floodplain restoration, and capturing excess winter runoff. The episode highlights the importance of adaptation, preparedness, and long-term planning as growers navigate an increasingly dynamic and unpredictable climate future.
