In this episode of the Vint Wine Podcast, host Billy Galanko sits down with Brenna Quigley, geologist and terroir specialist, to explore how what lies beneath the vines shapes what’s in your glass.

Brenna shares her path from UC Santa Barbara to working with mentors like Raj Parr and Seth Kunin, and with producers such as Quintessa, Flowers, and Hirsch. She explains how geology helps wineries understand vineyard character, canopy choices, and grape health. Together they discuss what terroir really means, the ongoing debate around “minerality,” and how soil chemistry, pH, and rock type, from limestone to volcanic, affect the style and texture of wine.

Key Topics:
• How geology shapes terroir, vine health, and flavor across regions
• Minerality vs. salinity and why these terms are often misunderstood
• Limestone, clay, granite, and volcanic soils and their impact on wine structure and acidity
• Vineyard mapping, soil pits, and auger cores in guiding farming and blending decisions
