Inside Winemaking - the art and science of growing grapes and crafting wine

This episode features Livermore Valley winemaker and consultant Meredith Sarboraria for a wide-ranging conversation recorded on location in the heart of the appellation. A proud self-described "Livermoron," Meredith traces her path from tasting room work in the late 1990s to earning her Viticulture and Enology degree at Las Positas College and building her consulting business, Barrel Down Wine Services. Along the way, she paints a vivid portrait of Livermore's wine country — from the outsized influence of Wente and Measure D on land preservation, to the region's sandy loam soils, marine-influenced climate, and its newly adopted signature varietals: Cabernet Franc and Sauvignon Blanc. She also shares candid insights into the valley's growing community of female winemakers and the collective they've built to support one another.
The conversation then shifts to winemaking craft, with Meredith diving deep on the challenges of working with high-acid Barbera, her philosophy of balance over manipulation, techniques for punch-downs in macro bins and T-bins, and the smart use of enzymes during fermentation. Jim and Meredith also preview an upcoming Inside Winemaking group trip to Valle de Guadalupe, Baja California — Mexico's oldest New World wine region — where Meredith has traveled three times and serves as the group's guide. She covers everything from crossing the border by shuttle to the region's savory, marine-influenced wines, its world-class restaurants, and the exciting mix of traditional and modern winemaking happening in the valley. The episode closes with Meredith sharing the childhood smells of Livermore that still bring her home.

In this episode Jim Duane sits down with Elizabeth Vianna to explore her unconventional path from pre-med student to one of Napa Valley's most respected Cabernet Sauvignon producers. Elizabeth shares how a late discovery of wine in New York City led her to University of California, Davis, and ultimately to a long-term career rooted in estate winemaking in the Stags Leap District. The conversation dives into the evolution of Chimney Rock's vineyard and winemaking philosophy, including its commitment to 100% estate fruit, the use of exclusively free-run wine, and the influence of site diversity on wine style.
The episode also goes deep on practical winemaking decisions, from extended maceration strategies and tannin management to sulfur timing, racking protocols, and blending philosophy. Elizabeth discusses her increasing focus on regenerative farming, vine health, and long-term sustainability in the face of climate change, as well as her approach to working with alternative white varieties like Sauvignon Gris and Fiano. Along the way, she reflects on mentorship, leadership, and the importance of helping the next generation of winemakers develop their own instincts—making this episode both technically insightful and personally grounded.

In this episode, viticulturist Patrick Riggs dives deep into the realities of organic farming in Napa Valley. We unpack what it takes to convert vineyards from conventional to organic, from soil testing and rethinking fertilizer programs to choosing equipment for under‑vine weed control and managing more volatile, season‑driven budgets. Patrick explains how tools and machinery for cultivation have evolved, how he approaches weed control without herbicides, and why organic systems demand a more diagnostic, problem‑solving mindset.
Patrick also details integrated strategies for managing vine mealybug organically—combining year‑round mating disruption, biological controls like parasitic wasps and mealybug destroyers, and very selective use of organic sprays. From there, we explore floor management, soil moisture dynamics, and irrigation strategy in drought years: when to irrigate, how to prioritize limited water, why shaded interior leaves can be "water hogs," and how canopy design and trellis choices are shifting to protect fruit in a hotter, drier future. We close with newer tools like Surround (kaolin clay), spore trapping for mildew risk, updated organic nematode approaches, and even a duck‑powered experiment to clean a reservoir overrun with Azolla.

This Jim sits down with James Molesworth, Senior Editor for The Wine Spectator, to trace James's unconventional path into wine—from a Francophile, academic household in Queens to blind-tasting Burgundy in a tiny West Village cellar, and eventually orchestrating tastings and writing for one of the most influential wine publications in the world. James reflects on formative mentors, the discipline and humility required to learn both tasting and journalism at a professional level, and how his anthropology background shaped his "observe and report" style of wine writing. He also unpacks Wine Spectator's mission to educate and entertain, the magazine's role in the global wine ecosystem, and how landmark moments like the post‑9/11 New York Wine Experience revealed the deep, relationship-driven core of the wine community.
The conversation then widens to a rich exploration of regional evolution and the future of fine wine, focusing especially on Bordeaux and Napa Valley. James explains how Bordeaux's garagiste era parallels Napa's cult Cabernet phase, how shifts in farming (organic, biodynamic, agroforestry, soil health, old vines) are reshaping ripeness, structure, and balance, and why Cabernet Franc is becoming more important on both the right bank and in Napa. He talks candidly about climate pressures, changing consumer behavior, and why he remains bullish on Napa's future—as long as the valley stays rooted in agriculture, terroir, and authentic hospitality. Along the way, James shares insider perspectives on how Wine Spectator chooses which wines to review, the power of storytelling versus scores, and his "bookshelf" model for building regional expertise.213

In this episode of Inside Winemaking, Jim Duane sits down with Matteo Abreu, fifth-generation Napa Valley farmer and part of the Abreu vineyard management family, to explore what it means to grow and farm at the highest level in one of the world's most demanding wine regions. Matteo shares his path into the family business, the realities of multi-generational vineyard management, and how Abreu approaches vineyard site selection, soil preparation, drainage, and long-term vineyard design. The conversation highlights the importance of matching the right varieties to the right sites, with a particular focus on Cabernet Sauvignon and Cabernet Franc, and how disciplined vineyard preparation sets the foundation for premium wine quality.
The discussion also dives into modern challenges and hands-on solutions in Napa Valley viticulture, including heat management strategies such as shade cloth, pre-irrigation cooling, and selective use of misting, along with crop load management and canopy decisions for Cabernet Franc. Matteo also shares insights into Abreu's small-lot winemaking philosophy, co-fermentation practices, and the limits of automation in both vineyard and winery operations. Beyond grapes, listeners will hear about Abreu's olive oil production, olive fruit fly management, and commercial blueberry farming, offering a broader look at how diversified, detail-driven farming supports both wine quality and long-term sustainability.
