Robert Fiore's path to winemaking took a remarkable trek through archeology and geophysics. Long before he was tasting grapes in the lead-up to harvest he was poring over data from ground-penetrating radar in the search for petroleum. But it turns out that knowing rocks and soil is a solid foundation for a deep understanding of great vineyards.Today Robert is winemaker at the long-celebrated Peter Michael Winery, producing wines of elegance and grace from diverse vineyards in both Napa and Sonoma.We had a great time hearing Robert's story from passionate wine-lover to world-class winemaker. He even brought rock samples to discuss wine country geology. For more visit: https://petermichaelwinery.com/
