Terroir, Time, and Tradition: Inside Domaine Drouhin with Philippe Drouhin Part 1

Send us Fan Mail [https://www.buzzsprout.com/2307588/fan_mail/new] Episode Summary In this episode of Harvesting Wisdom, Mike McMahon travels to Burgundy's Clos des Mouches to speak with Philippe Drouhin of the historic Joseph Drouhin estate. Philippe traces his family's winemaking story back to 1880, including the accidental discovery that led to Clos des Mouches' celebrated white wine, and explains how four generations have shaped the domaine's vineyards. The conversation moves into the fine details of terroir — how soil composition can shift dramatically within just a hundred meters, how compost and cover crops are tailored plot by plot, and why root depth (sometimes reaching 20 meters) plays a critical role in surviving drought without irrigation, which is prohibited in Burgundy. Philippe and Mike also discuss the accelerating effects of climate change, water availability, and how the estate manages three separate vineyard sites across the region. Why Listen Listen if you want a grounded, detail-rich look at what it actually takes to farm a multi-generational vineyard through changing climate conditions. This episode is ideal for wine lovers, growers, soil science enthusiasts, and anyone curious how a family business preserves both land and legacy across a century of change.

Ultra Bioattivo: Inside a Regenerative Farm Above Florence

Send us Fan Mail [https://www.buzzsprout.com/2307588/fan_mail/new] Episode Summary In this episode of Harvesting Wisdom, Mike McMahon visits a hillside farm overlooking Florence, Italy, run by a farmer practicing what he calls "ultra bioattivo" — an intensely biological, small-scale approach to growing over 40 varieties of vegetables and olives without any fertilizers, pesticides, fungicides, or herbicides for more than 12 years. The conversation, translated live from Italian, covers his unique composting process (a thermophilic phase followed by months resting in a forest windrow), his use of biochar, zeolite, and Korean natural farming principles, and how cypress trees and mulched water basins help recharge the aquifer instead of letting runoff carry chemicals downhill. Remarkably, the farm has partnered with the University of Florence on clinical trials showing measurable improvements in customers' gut microbiomes, and Mike connects this to his own water-saving trials with the University of Arizona using the same radicchio variety in the Yuma desert. The episode closes with a look at community: 200 subscribing families, dozens of partner restaurants, and a shared vision between Mike and his host — brothers from different mothers — to prove this kind of farming can work anywhere on the planet, including through education and a possible documentary collaboration. Why Listen Listen if you want to see regenerative, chemical-free farming in action — not as theory, but as a working business feeding hundreds of families and dozens of restaurants without a dollar spent on advertising.

Basil Bottle: Growing Food Anywhere Without Soil

Send us Fan Mail [https://www.buzzsprout.com/2307588/fan_mail/new] What if you could grow fresh basil, tomatoes, and edible flowers right in a bottle — without soil, pumps, or electricity? In this episode of the Harvesting Wisdom Podcast, Mike McMahon sits down with Christopher Brooks, founder and creator of Basil Bottle, to explore the power of passive hydroponics, food accessibility, and the healing connection between people and plants. Christopher shares his powerful personal story of growing up in foster care and discovering gardening at 13 years old while in juvenile detention. A simple marigold seed became more than a plant — it became a moment of hope, confidence, and connection. Years later, that experience helped inspire his work in sustainability, food systems, and accessible growing solutions. Together, Mike and Christopher discuss how Basil Bottle works, why passive hydroponics makes growing easier, how plants can thrive without soil, and why this simple system could be used in homes, classrooms, assisted living spaces, and communities with limited access to gardens. In This Episode: ✅ Christopher’s personal story of discovering gardening as a foster youth ✅ How growing a plant helped build confidence and connection ✅ What passive hydroponics is and how it works ✅ Why plants can grow without soil, pumps, or electricity ✅ How Basil Bottle uses water, nutrients, roots, and air gaps ✅ Why overwatering and underwatering are common plant problems ✅ Growing basil, cherry tomatoes, and edible flowers indoors ✅ How hand-pollinating tomatoes works ✅ Why food accessibility matters in urban communities ✅ The educational and therapeutic potential of growing plants ✅ How Basil Bottle could support schools, seniors, and beginner growers Why Listen Listen if you are interested in simple ways to grow food at home, sustainability, hydroponics, school garden education, or the healing power of plants.
