Podcast Episode 14: 50 Years of Viticultural Excellence with Andy Beckstoffer & Glass with a Grower, Oscar Renteria

In this episode of Grown in Napa Valley, NVG celebrates its 50th Anniversary by honoring two influential figures who shaped—and continue to shape—Napa Valley’s viticultural legacy. The episode begins with a rich conversation with Andy Beckstoffer, one of NVG’s founders, who shares the story behind the organization's creation and the pivotal moments that helped elevate grape growers from second-class status to key decision-makers in the wine industry. From advocating for the 75% appellation rule to establishing vineyard-designate branding, Beckstoffer reflects on the early battles for grower respect, the transition from commodity farming to quality-driven practices, and how the region found confidence in its own identity following the 1976 Judgment of Paris.

Then, we share a glass with the 2025 Grower of the Year Oscar Renteria, who reflects on his upbringing in a multi-generational farmworker family and his journey toward leading Renteria Vineyard Management. Oscar speaks with heartfelt optimism about resilience, legacy, and mentorship, emphasizing the importance of education, cultural pride, and finding joy in hard work. His leadership style—rooted in gratitude, empathy, and teamwork—embodies NVG’s mission and offers a forward-looking perspective for the next generation of Napa growers navigating uncertain times with hope and purpose.
