To reduce its environmental impact, Tenuta di Castellaro has optimized the use of sun and wind implementing two ancient Persian techniques: solar chimneys and the wind tower. Solar chimneys, also known by the Romans, were used to naturally capture sunlight and diffuse it within an interior. Today this system enables Tenuta di Castellaro to almost completely eliminate the use of electricity to light its winery. The wind tower, on the other hand, was used in the Middle East since the 10th century B.C. to harness wind power and create a natural climate control system, repurposed today in the winery for wine storage.
