Vineyard Underground
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.

074: Variation in Young Vine Training in Diverse Climates
In this solo episode, we take a deep dive into the many variables that influence young vine training in different climates. Listeners will gain a clear understanding of how climate, trellis selection, rootstock vigor, and regional weather risks shape vine training strategies. Fritz explains how cold-climate growers often rely on double trunks or “spare parts viticulture” to prepare for winter damage, while warmer-climate vineyards may benefit from fast-tracking techniques like green topping and one-shoot training for quicker vineyard establishment. We walk through scenarios where single-trunk systems are ideal, when to consider double trunks, and how the practice of renewing trunks every few years can extend vine longevity. We also break down when to use green topping, how to avoid bull canes, and why mature leaves on developing trunks should never be removed. Growers will leave this episode with specific, actionable tips to match their training approach to their unique vineyard conditions, helping them improve both short-term success and long-term vineyard health. In this episode, you will hear: Differences between trellis systems and vine training systems When and why to use single vs. double trunk strategies What “spare parts viticulture” is and where it makes sense Green topping and other fast-tracking methods explained How to manage training for high- and low-vigor vineyard sites Follow and Review: If you enjoyed this episode, be sure to follow the podcast and leave a 5-star review on Apple Podcasts!

073: Soil Nutrient Interactions and the Role of Potassium in Eastern Vineyards with Dr. Jaclyn Fiola
In this episode of Vineyard Underground, Fritz welcomes soil scientist Dr. Jaclyn Fiola for an in-depth discussion on one of viticulture’s most misunderstood nutrients — potassium. Drawing from her recent research and extensive fieldwork across the Mid-Atlantic region, Jaclyn breaks down how potassium behaves differently from other macronutrients, where it originates in the soil, and what makes its availability so complex for grape growers. Fritz and Jaclyn explore why vineyards in the Eastern U.S. often see discrepancies between soil and tissue potassium levels and how that can impact grape quality, vine health, and ultimately wine pH. They dive into the implications of both potassium deficiency and excess, emphasizing how water availability and soil mineralogy play pivotal roles in potassium uptake. Growers will also learn why standard soil tests may not give the full picture — and why plant tissue testing, particularly whole-leaf sampling at veraison, is often more reliable. Jaclyn shares the results of her groundbreaking study, highlighting best practices for sampling, how to interpret potassium levels accurately, and actionable steps for managing young versus mature vines. Whether you're planting a new vineyard or managing high potassium levels in an existing one, this episode equips you with the tools to make more informed nutrient management decisions. In this episode, you will hear: Potassium largely comes from soil parent material, not organic matter, making it harder to assess with traditional testing. Moisture-rich soils increase potassium availability, especially in non-irrigated Eastern vineyards. Whole-leaf tissue testing at veraison gives the most accurate indication of potassium status in grapevines. Too much potassium can raise wine pH, affecting mouthfeel, color, and shelf life. Before applying potassium fertilizers, understand your soil minerals and use targeted tissue testing to avoid overcorrection.

072: How Research Influences Our Spray Program Decisions with Dr. Katie Gold
In this episode of Vineyard Underground, host Fritz Westover welcomes Dr. Katie Gold, Assistant Professor of Grape Pathology at Cornell University, for a deep dive into how research drives informed spray program decisions in the vineyard. Dr. Gold brings her extensive expertise in grape disease management to the conversation, shedding light on how growers can use scientific data and field research to refine their fungicide strategies and protect their crops more effectively. Fritz and Katie explore the critical role of disease forecasting models, including how they are developed and validated, and why it’s important for growers to go beyond the “calendar-based” approach to spraying. Dr. Gold emphasizes the value of using weather-based decision support tools and highlights ongoing research aimed at improving the precision and sustainability of vineyard disease management. Listeners will gain a better understanding of how academic research translates into real-world applications, from identifying pathogen resistance patterns to making timely fungicide applications. Katie also discusses the impact of underutilized research, how misinformation can spread in farming communities, and why continuous learning and outreach are essential for successful vineyard operations. In this episode, you will hear: Research-based spray programs outperform calendar-based models Disease forecasting tools help optimize fungicide timing and efficiency Growers should verify the reliability of sources when seeking vineyard advice Understanding fungicide resistance is key to long-term vineyard health Practical research translation is essential for sustainable vineyard practices Follow and Review: If you enjoyed this episode, be sure to follow the podcast and leave a 5-star review on Apple Podcasts!
