293: How Solar Panels Can Improve Vine Resilience and Wine Balance
Rising temperatures and erratic weather accelerate ripening, spread disease faster, and shift sugar, alcohol, and acidity levels. All of which threaten wine quality and style.
At Geisenheim University, Dr. Manfred Stoll is testing "vitivoltaics": semi-transparent, trackable solar panels installed above vines. The system moderates heat, radiation, and extreme weather, while improving young vine establishment and water infiltration. Beyond the vineyard, this renewable energy can power everything from irrigation pumps to EV charging stations for wine tasting guests.
