What if you could hang out with experienced grape growers, ask them about the science of grape growing, vineyard operations, and more; then take an insight or two to improve your vineyard and ultimately the quality of the wines you produce? That’s what we do each week on the Vineyard Underground. Hosted by Fritz Westover –– viticulture expert more than 20 years of experience in the vineyard industry –– every episode is an in-depth look at grape growing methods, care, and even complicated matters of fertilization and pest and disease management? The goal is to provide you with an understanding of the complicated aspects of viticulture science so that experienced and even first-time grape growers will be able to understand and implement new practices in their vineyard.2022 Arte Comida y Vino

    077: Transitioning Vineyards to Regenerative Organic Certification with Hilary Graves
    Aug 5 2025
    In this episode, we welcome Hilary Graves, Vineyard and Grower Relations Manager at Booker Wines, to discuss how she successfully transitioned an Organic vineyard to regenerative organic certification. With over 20 years of field experience on California’s Central Coast, Hilary brings practical strategies and candid stories about what it really takes to move beyond standard organic practices. Hilary explains the core pillars of regenerative organic certification — soil health, social fairness, and animal welfare — and why she and the team at Booker Wines chose to pursue this path. She walks listeners through how integrating multi-species cover crops, implementing low-till and no-till practices, and bringing in grazing livestock have helped improve soil structure, increase water retention, and reduce reliance on inputs. Fritz and Hilary also dig into the challenges of vineyard mechanization on steep terrain, minimizing tractor passes, and creative pest control strategies, including releasing predatory lacewings by drone to combat leafhoppers. Whether you’re already farming organically or just exploring what’s next, this episode offers tangible examples of how even small changes can drive long-term benefits for your soil, your business, and the environment. In this episode, you will hear: The difference between organic and regenerative organic certification How to build a diverse cover crop blend (and why 15 species might be better than five) Using a Yeomans plow to increase water infiltration without disturbing soil structure Grazing sheep for cover crop termination in a mutually beneficial partnership Why releasing beneficial insects by drone can outpace traditional sprays for pest control Follow and Review: If you enjoyed this episode, be sure to follow the podcast and leave a 5-star review on Apple Podcasts!

  • 076: Growing Grapes Around the World – England with Dr. Belinda Kemp

    076: Growing Grapes Around the World – England with Dr. Belinda Kemp
    Jul 22 2025
    In this episode of Vineyard Underground, we welcome Dr. Belinda Kemp, viticulture and enology researcher at NIAB in East Malling, England, to explore the evolving wine industry in the UK. With a background in theatrical arts and a PhD in Pinot Noir, Dr. Kemp brings a dynamic perspective to the scientific and practical aspects of cool climate viticulture. The conversation covers England’s emerging reputation for sparkling wine, the impact of climate variability on grape production, and the country's increasing focus on sustainability and innovation. Dr. Kemp discusses the shift from traditional varieties like Chardonnay and Pinot Noir toward disease-resistant hybrid grapes, including the introduction of PiWi varieties. She shares the challenges of managing common diseases like downy and powdery mildew and emerging threats like black rot. Listeners also get a glimpse into the latest research projects at NIAB, including the effects of pruning methods on yield, the role of calcium in sparkling wine stability, and the use of companion plants to improve vineyard biodiversity. Dr. Kemp explains how NIAB integrates technology and sustainability — from acoustic soil monitoring to underground rhizolabs — to support growers and improve wine quality. Whether you grow grapes in England or a similar cool, wet climate like the eastern U.S. or Canada, this episode offers applicable knowledge for tackling vineyard challenges and embracing innovation. In this episode, you will hear: England's wine industry is expanding rapidly, with a strong focus on sparkling wines New disease-resistant grape varieties are being trialed to meet climate and production demands Variability in spring weather creates challenges for cover crops, planting, and pest pressure Calcium stability is becoming an issue in sparkling wine production — NIAB is studying causes and solutions Companion planting and acoustic soil monitoring are part of a systems approach to regenerative viticulture Follow and Review: If you enjoyed this episode, be sure to follow the podcast and leave a 5-star review on Apple Podcasts!

  • 075: The Importance of Mycorrhizal Fungi for Vineyard Health with Dr. R. Paul Schreiner

    075: The Importance of Mycorrhizal Fungi for Vineyard Health with Dr. R. Paul Schreiner
    Jul 8 2025

    In this episode of Vineyard Underground, Fritz welcomes Dr. R. Paul Schreiner, recently retired research plant physiologist from the USDA, for a deep dive into the fascinating world of mycorrhizal fungi and their impact on vineyard health. With over two decades of research experience in grapevine physiology and root biology, Dr. Schreiner shares the critical roles these fungi play in nutrient uptake, root efficiency, drought tolerance, and overall soil structure.

    Fritz and Dr. Schreiner explore what arbuscular mycorrhizal fungi (AMF) are, how they form symbiotic relationships with grapevine roots, and why grapes are considered “super hosts.” They discuss how AMF enhances phosphorus acquisition, especially in low-P soils, and how they support the uptake of other nutrients like potassium, zinc, and copper. They also talk about factors that suppress or encourage fungal colonization, such as excessive fertilization, cultivation, cover cropping, and herbicide use.

    Dr. Schreiner also previews ongoing research from the High-Resolution Vineyard Nutrition Project, which is helping redefine best practices for tissue sampling and nutrient timing. Whether you’re planting a new vineyard or managing an established one, this episode offers an essential look at how understanding underground biology can elevate your vineyard management decisions.

    In this episode, you will hear:

    • How grapevines form symbiotic relationships with mycorrhizal fungi

    • Why phosphorus is the most important nutrient supported by AMF

    • The effects of nitrogen and phosphorus fertilization on fungal colonization

    • Whether commercial AMF inoculants are worth the investment

    • Practices that promote healthy fungal populations in vineyard soil
